->'''Liu Kang:''' My heart belongs to another.\\
'''The Nostalgia Critic:''' Your heart belongs to another? Who? Kitana? That chick you've known for less than an hour? How does she own your heart? True, you just met this other woman, but give her a few minutes and you'll have known her just as long.
-->-- ''WebVideo/TheNostalgiaCritic'' reviewing ''Film/MortalKombatAnnihilation''[[note]]Liu and Kitana had actually known each other for a week or two (the entirety of the previous movie) by then, but the point still stands[[/note]]

DeusExMachina as the flop of a RomanceArc. "Smooch Ex Machina," if you will.

Not every RomanceArc gets the luxury of being played out fully to the [[TheLawOfConservationOfDetail last detail]]. Sometimes the writers decide that the important part is getting those two characters in a relationship, and [[HandWave the rest will somehow sort itself out]]. The result is that the two characters go through a leap of characterization all the way to a RelationshipUpgrade without any of the usual in-betweens; apparently Cupid forgot to tie the RedStringOfFate on the lovers' pinkies at birth, and in a desperate attempt to save face he ended up garroting them with it in a back alley while he thought the audience wasn't paying attention.

Possibly the two characters have had little to no interaction prior to their sudden onset of romantic involvement; or they had, and even plenty, but it was never romantic in nature, and seems to have spontaneously transformed into such without any apparent reason. In more borderline cases, this can happen even when the two characters ''have'' shown interest in each other, in some form or another; it's the placement, pacing and timing that are off. An audience tends to know the kind of emotional process a person goes through when entering a romantic relationship, and will not be happy past a certain line of too little of this process and too much conveniently dramatic payoff.

Remember, TropesAreTools: By itself a relationship that doesn't get painstakingly detailed development is not automatically bad, and like any other plot development, there are cases where it just needs to be done with and make place for more important things. [[TheyWastedAPerfectlyGoodPlot Sadly, the case is often the opposite]] - the romance ''is'' the important thing, and, in spite of that, the author just didn't figure the "how it comes to happen" part was very important. The subsequent lack of "volume" in the RomanceArc, in turn, begs for compensation: having characters fall for each other out of nowhere can make any romance come across as a TokenRomance, and hence what often happens is that the writers start firing every possible drama cannon so as to impress upon the viewers that ''this is important'' and ''they should care''. The characters don't merely start dating nor just fall in LoveAtFirstSight; they are thrown into a state of immense amorous passion, starry eyed, IntertwinedFingers, [[TrueLovesKiss kissing passionately]], and [[ThePromise promising]] each other an eternity of happiness simply BecauseDestinySaysSo.

[[CharacterDerailment Characters may be derailed]], and [[DerailingLoveInterests competing love interests particularly so]]; {{Narm}}y moments and RelationshipSue transformations may become a frequent sighting; chemistry and interaction is prone to be reduced to the SickeninglySweethearts sort, if there was any to begin with. In more degenerate cases, the relationship may undergo a malignant mutation into a RomanticPlotTumor, taking the focus off the more important aspects of the story. Cue [[{{Shipping}} one part]] of the audience [[SugarWiki/AndTheFandomRejoiced sighing happily]], since [[FanPreferredCouple those two were obviously made for each other]], and it's about time, while [[BrokenBase the other part]] of the audience scratches their heads in bewilderment and disdain, since this "development" just asked for too much WillingSuspensionOfDisbelief and feels suspiciously like the writers just [[AssPull pulled it straight out of their hindquarters]]. [[ShipToShipCombat Arguments]] may break out regarding how well-[[{{foreshadowing}} foreshadowed]] and well-handled the whole thing was.

A LastMinuteHookup can result in this trope, or serve as damage control. The potential problems are all still there, but at least they're not going to grow out of control throughout the rest of the plot since there's no rest of the plot left. Still, this can make [[PostscriptSeason unexpected sequels]] [[DowntimeDowngrade rather awkward]], even assuming that [[FanonDiscontinuity the audience can stomach the original strangulation]]. If the work is an adaption, it may be an AdaptationInducedPlotHole. The couple may have evolved over time at the original work, and the adaption may rush things into the romance, because it's one of the key aspects of the original work and ''has'' to be included, no matter what.

May be caused by TheDulcineaEffect. For when the build-up takes place before the series, see NewOldFlame. When this happens to minor characters and is less noticeable, it's a case of PairTheSpares. Can crop up when the writers want to quickly counteract HoYay, IncestSubtext, or a RelationshipWritingFumble. Often results in an {{Audience Reaction|s}} version of ICantBelieveAGuyLikeYouWouldNoticeMe or WhatDoesSheSeeInHim. Compare ShipsThatPassInTheNight for {{fanon}} couples like this. Compare and contrast DesignatedLoveInterest.

'''Note''': While some of the examples are universally agreed upon, this trope can get very subjective due to ShipToShipCombat, ShippingGoggles, or plain disagreements. [[RuleOfCautiousEditingJudgement Keep a few points in mind when editing]];
# Refrain from using this trope to whine about a pairing that [[DieForOurShip you personally don't like]].
# If you add an example, be sure to explain ''why'' you feel the couple fits this trope. Make sure it fulfills ''both'' requirements; it fits the description of ways development can be "off" ''and'' leads to at least one of the consequences listed above.
# If you feel a certain pairing is badly handled, that doesn't mean it's this trope. If the pairing took a long time to build up and execute, it does not belong here, no matter how badly written the actual romance is. That's more likely a RomanticPlotTumor.
# Most importantly, a couple falling into this trope does not automatically mean they are a bad couple, so there is no need to go ballistic and start an Administrivia/EditWar if you see your favorite couple on here. A couple can fall under this trope and still be a very great couple, just like a DeusExMachina does not automatically make [[ShockingSwerve a plot twist a bad one]].

Has absolutely nothing to do with TheRedStapler. If someone literally uses a red string on someone else to make them fall in love with them, it's a LovePotion.

!!Warning: potential spoilers abound.


[[folder:Anime and Manga]]
* In all adaptations of ''Manga/{{Area 88}}'', flashbacks show Ryoko falling in love with Shin after only having known him a few minutes. The two characters have nothing in common, and neither one understands what makes the other tick. The sole purpose of the relationship seems to be that Shin will have someone to pine for during his involuntary servitude at Area 88.
* ''Anime/AquarionEvol'' has Kagura and Zessica. Both spent all the story chasing after their respective love interest, and never had any single interaction in the entire show. Come the final episode, both of them get rejected and suddenly they are interested in each other. It all looked very forced, starting with Kagura suddenly saying he thinks Mikono and Amata make a lovely couple, when one episode ago he was fighting Amata over her and screaming about never giving her up to anyone. It was obvious they did this to get them out of the OfficialCouple's way, but for it to make sense you'd have to forget everything about Kagura and Zessica's whole character and everything that happened before.
* ''Manga/AyashiNoCeres'':
** From the first moment Aya and Toya meet it's obvious that they would be the OfficialCouple, but the whole thing happens too fast and very awkwardly. Basically, they've had at least ''five minutes'' of interaction in different scenarios until Toya takes Aya to his apartment where she suddenly declares that she loves him. ''Slightly'' justified by [[spoiler:him being an evolved life form made out of a divine energy ball and was basically wired to serve and protect his family, hence the instant love for application of this instinct]].
** [[FanPreferredCouple Aya and Yuuhi]] come across as this in the final chapter. Yuuhi has been in love with Aya the entire series, [[PairTheSpares with hints of him and Chidori as a potential couple at times]], and he seems to have [[IWantMyBelovedToBeHappy accepted Aya and Toya being together]]. Then the final chapter has [[spoiler:Toya telling Yuuhi that he was likely going to [[DeathOfTheHypotenuse die soon]] and that Yuuhi should take care of Aya and their child when that happens]].
* At the very end of ''Manga/BokuNoFutatsuNoTsubasa'' the long series of romantic arcs end with [[spoiler:Mako and Hiromi ending up together]] which had never been hinted at all and [[spoiler:Hiromi is the very reason Mako comes back to Earth -- instead of going down the cousin[=/=]sister relationship route that had been developing since the start]].
* Daikichi and [[spoiler:Rin]] in the ''Manga/BunnyDrop'' manga. They have a very strong bond throughout the manga, yes, however it's not presented as anything but [[spoiler:familial]] until after the {{timeskip}}.
* Ohgi and Villetta of ''Anime/CodeGeass'', hoo boy. The former falls in love with the latter [[AmnesiacDissonance even though she is a Britannian spy under amnesia]]. Even after she tries to kill him after regaining her memories, all it takes for their relationship to continue is Ohgi [[TakingTheBullet shielding Villetta from kunais thrown by Sayoko]]. Not to mention that Villetta was spying on Lelouch, keeping him from going back into the rebellion full-stop for the sake of her being a Baroness, and Ohgi later takes her spotty evidence on him regarding Geass to heart in betraying him. It's not so much about it being an unbelievable romance plot as it is a serious case of CharacterDerailment for Ohgi, who has let [[LoveMakesYouDumb his love for Villetta]] go to his head, and trust the latter, who isn't the most reliable source of information, over Lelouch, who while questionable himself, has still done more good than bad for the Black Knights, and [[KangarooCourt never even gets the chance to explain himself]].
* The relationship between [[BadassBookworm Johnny Burnett]] and [[IdolSinger Eida Rosso]] in ''Anime/DancougarNova'' comes out of nowhere, feels rushed and never serves much of a purpose.
* In ''Anime/DarlingInTheFranxx'', Hiro and 02 have known each other for about a week before the power of their love cures [[spoiler:Hiro]]'s cancer. Admittedly, SuperpowerfulGenetics helped, but the guy was coughing up blood before his LoveEpiphany somehow made the tumor recede within ''seconds''. Then he got up and defeated a klaxosaur ten times his size. In a series otherwise completely devoid of magic, this development came off as [[{{Asspull}} implausible]] and saccharine.
* ''Anime/DigimonAdventure02'':
** Yamato and Sora are the primary OfficialCouple of both ''Digimon Adventure'' and ''Adventure 02'' and are an exceptionally complicated example that [[http://knowyourmeme.com/memes/matt-x-sorasorato-threads generates rage to this day]]. Head director Hiroyuki Kakudou [[https://twitter.com/kakudou/status/339004461424971776 always intended to pair Yamato and Sora off]] because he considered it a [[http://digitalscratch.pmsinfirm.org/?p=822#08 cliché]] to pair the male and female leads. However, because the series was never actually about relationships, their intended romance was never openly developed and was given only [[https://twitter.com/kakudou/status/340404941917151233 a smattering of subtle foreshadowing]]. Unfortunately, Kakudou's intentions were stymied repeatedly due to trying to balance Sora and Yamato's future romance with Sora and Taichi's current friendship; CreativeDifferences he had with other series contributors; and the fact that he had a bad habit of [[LockedoutOfTheLoop not sharing his plans with the other creators]]; many of the voice actors themselves related surprise and disbelief about Sora and Yamato pairing, including Creator/YukoMizutani.
*** In fact, where Kakudou wasn't ''directly'' involved, the creative trend inevitably slid towards developing Tai and Sora. Creator/MamoruHosoda, another major series director, introduced a romantic sub-plot between them in ''[[TheMovie Our War Game]]'', rife with ShipTease. The staff behind the Fox Kids dub, including head writer Jeff Nimoy, openly preferred them as a pair, which [[FanPreferredCouple they considered to be the more plausible couple]] and [[WriterOnBoard emphasized it in their writing]]. Back on Kakudou's end, efforts were taken to ensure his vision, which led to the infamous ChristmasEpisode in which Sora and Yamato, who were now OutOfFocus along with the rest of the original cast, became the series' Official Couple; in the States, this became a spontaneous LoveTriangle with [[DidNotGetTheGirl a tragic outcome for Tai]]. At this point the RelationshipWritingFumble was growing out of control, leading to the franchise producing [[AllThereInTheManual supplementary materials and the drama CDs]] trying to develop it; the ''Digimon Adventure'' PSP game recast the whole affair as a love triangle, which was [[https://twitter.com/kakudou/status/340757798776348672 completely against Kakudou's vision.]]
** The second official pairing [[spoiler:Ken and Miyako]] doesn't fare much better. Yes, she [[{{Fangirl}} expressed interest in him earlier]], but only barely interacted with him for the rest of the show. Their marriage appears to have been an example of a RealLifeWritesThePlot CastingGag; they were paired off in the DistantFinale [[http://digitalscratch.pmsinfirm.org/?p=822#08 because their voice seiyuu got along so well with each other.]]
* ''Manga/{{DNA2}}''
** Played with between Junta and Karin. Karin always planned that, once she found a guy she wanted to settle down with, she'd simply shoot him with a DMC bullet that altered him in a way to love her. And when Junta shows interest in Karin, she thinks she accidentally shot him with said bullet. It turns out to not be the case and their mutual feelings come from themselves.
** Played straight with Junta and Ami. The two have been friends since they were children, with Ami obviously carrying a torch for him, but not [[CannotSpitItOut saying anything]] and Junta simply seeing her as a childhood friend. At the end of the story, Karin decides to [[FishOutOfTemporalWater return to the future]] and shoots Junta with one last DMC bullet to remove the playboy DNA [[LaserGuidedAmnesia and any memory of her and the events that transpired]], with Junta last seen meeting Ami.
* ''Manga/DoctorSlump'': A lampshaded and PlayedForLaughs example. In early chapters Senbei and Midori have an embarrassing stalker/LustObject type of relationship and Midori seems mostly oblivious to Senbei's love for her. Then at some point, there was an AccidentalProposal while Midori was in the bathroom: she overhears, immediately accepts, and the next thing you know, the two are hitched. They are HappilyMarried for the rest of the series. This was intentional since the author explicitly stated he doesn't like writing romances. Downplayed in later chapters since Arale/Obotchaman, Taro/Tsururin, and Akane/Tsukutsun have slightly more developed relationships (WordOfGod stated that all these relationships were his editor's ideas).
* Most pairings in ''Manga/DragonBall'' and its continuities (though Gohan/Videl actually averts it, since the two take a while to develop their feelings). A few characters marry and have kids during the series's frequent time skips with little on-screen development. To the author's credit, the reason for the lack of development is because he's stated in interviews that he doesn't care for romance, and most of the couples hook up during a TimeSkip of several years, [[FanficFuel allowing the readers' imaginations to run wild]].
** Vegeta and Bulma actually became a fan favorite relationship partly due to this trope. The romantic competition (poor Yamcha) was dumped so suddenly, and the sudden hook up was so unlikely (they had barely spoken, and he had killed her boyfriend and many of her friends) that it ended up being hilarious. It helps that they didn't actually get legally married - they just hooked up and had a kid together, and it took a while for their relationship to become an actual loving one.
%%* Depending on who you ask, this is what happened to Suzume and Mamura in ''Manga/HirunakaNoRyuusei''.
* The original ''Anime/MobileSuitGundam'' has Amuro Ray and Lalah Sune, who despite being on opposite sides of a war, instantly fall in love the first time they meet. It's justified in-universe by their PsychicPowers causing them to mindlink and thus know each other better than they know anybody else, but that doesn't make the relationship anymore real to the audience or give us a reason to care about them.
* ''Anime/MobileSuitZetaGundam'':
** [[TelepathicSpacemen Newtype]] romance ended up becoming a staple of the franchise, with one of the most blatant examples being Kamille Bidan and Four Murasame. They spend about twenty minutes in each other's company and suddenly can't live without each other, despite being opposite sides, and Four at least was initially characterised as a borderline psychopath and only got HiddenDepths later (whereas Lalah at least was a [[NiceGuy Nice Girl]]). Many fans like the relationship despite this, not least for the CharacterDevelopment it forces onto [[{{Jerkass}} the previously unlikable]] [[JerkWithAHeartOfGold Kamille]].
** Amuro and Beltorchika Irma are making out for the third time an episode after meeting, though this is somewhat justified in that Amuro was trying to unconsciously use Beltorchika as an "excuse" to not go into space and relive the utter trauma he was into. In Amuro's [[Anime/MobileSuitGundamCharsCounterattack next appearance]], he is already with Chan Agi, another girl he barely talks to -- apparently, because of ExecutiveMeddling that didn't let the creators use Beltorchika's character as Amuro's ''CCA'' girlfriend. Notably, Creator/YoshiyukiTomino penned a novelization of ''Char's Counterattack'' called ''Beltorchika's Children'', which was specifically written to be adapted as a film (Creator/{{Sunrise}} instead chose to adapt ''High Streamer'', an earlier work of Tomino's); in it, Beltorchika appears in Chan's place and assumes her role, only she is explicitly noted to be pregnant with Amuro's child and [[spoiler:survives the events of the novel as opposed to Chan in ''CCA'' proper]].
* In ''Anime/MobileSuitGundamSEEDDestiny'', Shinn and Lunamaria who up to then had been JustFriends get together right after he has apparently ''[[YouKillItYouBoughtIt killed]]'' her previous love interest and her little sister. It can be argued that Lunamaria was suffering of Post Traumatic Stress Disorder and neither she nor Shinn were thinking straight, but... even their ''fans'' dislike how they hooked up. Making this somewhat more prickly is the WordOfGod statement from director Mitsuo Fukuda that their relationship was the only pure one in the whole series, which fans of the other couples took as a giant middle finger. Since Creator/KenichiSuzumura and Creator/MaayaSakamoto (Shinn and Lunamaria's [=VA=]s, respectively) got married in real life in 2011, this became ''both'' {{Hilarious|InHindsight}} and HeartwarmingInHindsight.
* This is ''especially'' prevalent with Asemu Asuno and Romary Stone in ''Anime/MobileSuitGundamAGE'': After joining the military, they very rarely interact on-screen and neither of them seem to get past the point of "I like you but [[CannotSpitItOut what are words]]" for the whole series, plus Romary has feelings for both him and Zeheart. To resolve this, there is a flashback to one conversation between them in Episode 28 and then the generation ends with the wedding. It does ''not'' help either, though, that Asemu and Romary's relationship was already more of a default given than anything else right from the beginning: Their son in the Third Generation, Kio, had been leaked to have Romary's hair color ''[[ShipSinking even before the entire series has started airing in the first place]]''.
* ''Manga/{{Naruto}}'': What seems to be a straight example in the epilogue turns out to actually be a {{zigzag|gingTrope}} in the PostScriptSeason. The second-to-last chapter of the original series seems to imply that AxCrazy RivalTurnedEvil Sasuke has finally seen the error of his ways, and will try to make amends for the horrible way he has treated his former teammate Sakura, who has [[LoveMartyr gone through hell on account of her irrationally persistent love for him]]. The DistantFinale reveals that Sasuke and Sakura ended up married and had a daughter together. Theoretically, this might have made logical sense given the time scale, but from the viewers' perspective, one moment Sasuke was trying to kill Sakura, showing utter indifference for her well-being and openly rejecting her (even invoking WhatDoesSheSeeInHim on himself), and the next moment he was married to her. Back in the beginning of the series they ''did'' have some romantic interaction, but by the later parts Sasuke had become so hostile to Sakura that this sudden turn to marriage and offspring was completely unpredictable and impossible to understand unless you were wearing ShippingGoggles. This is later rounded out in ''Manga/NarutoGaiden'': The faults of the relationship are brought under the spotlight and explored. They are not resolved, but the story makes clear that [[AwLookTheyReallyDoLoveEachOther Sasuke and Sakura are still very much in love with each other]], in spite of it all.
* Adette and Gouly from ''Anime/OvermanKingGainer'' are both leaders of their respective squads but do not talk much and never have a romantic moment until the final two episodes. Adette kisses Gouly to awaken him from being BrainwashedAndCrazy and the next episode sees her holding him and flirting with him. The only setup is the fact that Adette loves strong men, and Gouly is a badass ninja. Apparently, the Banpresto developers did not like the handling of the Adette/Gouly pairing; in ''VideoGame/SuperRobotWarsK'', this ship is [[ShipSinking unceremoniously sunk]] when Adette gets back with her previous love interest after the Overdevil's defeat.
* ''Manga/RanmaOneHalf'':
** Apparently the demand for Ryoga to get a happy ending led to the creation of Akari Unryu, who is so perfect for Ryoga, and shows up few times in her subsequent appearances.
** Mousse got some major attempts at redeeming his character, which can actually come off as rather jarring due to spending the early series trying to kill Ranma, and once boasted along the lines that he would gladly break any rules and forsake any honor to get Shampoo, though Shampoo never changed her opinion of him - while she did occasionally show him some "soft" moments, she spent most of the series outright abusing him and on one occasion was perfectly willing to go and play video games while abandoning him to what she believed would be certain death at the hands of a life-sapping demon.
** Ukyo got an (attempted) and very literal LastMinuteHookup in the form of an effeminate transvestite ninja master, Konatsu, who appeared less than Akari did (this relation is still ambiguous).
** For some fans, even Ranma and Akane, for their tense relation and constant fights.
* Creator/JunjiIto wrote a short story called ''Red String'' in which this trope is played out literally and, and since it's Junji Ito, with a nice dose of body horror.
* Tails and [[SpotlightStealingSquad Cosmo's]] relationship in season three of ''Anime/SonicX''. There's really no reason why Tails fell for Cosmo so suddenly, or why Cosmo was paired up with Tails instead of any of the other (and older) males on the Blue Typhoon. And this pairing was strangled together even in-universe. In one particular episode, the Chaotix try several methods to pair the two together. They do this because... um... well, uh... BECAUSE!
* The manga version of ''Manga/SorcererHunters'' does this with the Carrot/Tira pairing. While it's made clear how Tira feels about Carrot, Carrot's own feelings are rarely brought into question, and even the few moments where he ''does'' seem to notice her as more than a sister figure seem to fall short of convincing anyone this hook-up happened for any other reason other than that they were [[BecauseDestinySaysSo destined all along]].
* Thanks to the TimeSkip, pretty much any canon couple in ''Anime/TengenToppaGurrenLagann'' save for Simon/Nia and Kamina/Yoko.
* ''Manga/UruseiYatsura'':
** A case where this might actually be the ''happy ending''; initially Shinobu, the {{Tsundere}} with SuperStrength, seems to be the [[ChildhoodFriendRomance Unlucky Childhood Friend]], though she legitimately falls out of love with Ataru Moroboshi due to recognizing that he is an apparently irredeemable LovableSexManiac. Her next choice of crushes? HandsomeLech and RoyalBrat Shuutaro Mendo, who's not only just as bad as Ataru in terms of lustfulness, but is also chasing after CuteMonsterGirl Lum. Meanwhile, she's being pursued by the {{gonk}}iest character in the series, a hulking, repulsive moron who repeatedly tries to ambush her. Finally, she earns the attention of Inaba, a shy and clumsy, but sweet, innocent and genuinely romantic character, whom she grows quite fond of. [[StarCrossedLovers And then he only shows up in about one story.]]
** Ryuunosuke has a similar case happen to her at the end of the manga. Towards the end she gets betrothed by her father to Nagisa, the cross-dressing son of her father's friend. Nagisa however, only appears in two two-part storylines in the manga, and an OVA, and the big manga finale.
* Takanashi and Inami of ''Manga/{{Working}}''. On a series that works on StatusQuoIsGod, Takanashi goes from not liking being with Inami but having his nice moments with her, to blindly loving her more than anyone else in the world with zero explanation, despite Inami being the exact opposite of his tastes and, well, [[DoesNotLikeMen punching him on the face when he gets close]]. And no, him liking her doesn't make her stop punching him.
** This becomes somewhat {{averted|Trope}} by the 3rd season of the anime, where Inami's androphobia gets better to the point that she no longer punches Takanashi on sight, and he is even able to make physical contact with her and hold her hand. Takanashi himself also begins to notice how nice and cute an Inami that doesn't hit men is.
* Yusei and Aki in ''Anime/YuGiOh5Ds''. There are maybe seven or eight episodes in a 154-episode series where they have any significant interaction, and Aki spends the first four of those episodes trying to murder Yusei. Immediately after the last of those four episodes, at which point they've spent less than an hour of real time together, she immediately falls in love with him and the majority of her dialogue becomes SayMyName. Even after that, Yusei has more interaction with Kiryu over the course of Crashtown's six episodes than with Aki over the entire series. This one could be justified by Yusei not being comfortable with Aki's interest in and devotion to him, when she'd previously been fairly unstable, but it's never brought up, thanks to Aki being severely DemotedToExtra.
* ''Anime/YuGiOhArcV'' has Yuri and Serena, who are one of four pairs of dimensional counterparts. In the final episode, there's a scene of the two of them looking at each other fondly, in parallel with the other pairs, implying that they're destined for one another. The problem? The other three pairs had at least some prior offscreen interaction or relationships, while the above scene is one of the only times that Yuri and Serena have even been onscreen together - and Yuri is an unrepentant villain while Serena is an AntiHero at worst, which makes this even more absurd.
* More or less parodied in ''Manga/YuYuHakusho'', where Kuwabara sees Yukina on a video tape once and decides that she is his soul mate and even provides a visual of the RedStringOfFate. When he finally meets her and treats her almost like this, she seems more confused than anything and just goes along with it. Toward the end of the series, though, the relationship does seem to be on a more serious note.
* Sorta alluded to in ''Manga/ZettaiShoujoSeiikiAmnesian'', where Himeko feels that Chikane's utterly intense devotion and love for her is too rushed. Granted, this happened twice before (in ''Anime/KannazukiNoMiko'' and ''Anime/ShatteredAngels''), it shouldn't be surprising.

[[folder:Comic Books]]
* ''ComicStrip/NineChickweedLane'': Gran/Edna's flashback arc ends with a subversion: She chooses to stay with Bill (whom she hadn't seen in over a decade and only days earlier thought was dead), rather than Peter Kiesl, whom she was days away from marrying at that point. This is portrayed as a massive mistake by all parties, Edna for [[HonorBeforeReason choosing to honor a promise]] made a decade ago rather than stay with her true love, Peter for letting said love go without a fight (then spending half a century pining for her), and Bill for accepting her choice - [[spoiler:even after they find out she's pregnant with Peter's child]] - rather than send her back to the man she truly loved.
* ''Comicbook/FantasticFour'': Torch and Crystal barely even speak ''three sentences'' to each other before declaring themselves lovers-for-life, and the Torch spends the next ''several'' arcs pining over Crystal. Still, Johnny was awfully young in those days, but it's not as if he and Crystal stayed together for very long after they ''were'' reunited. Subverted in ''ComicBook/UltimateFantasticFour'', where he quotes the 'Lovers-for-life' verbatim... then shrugs and admits "[[TheCasanova I just thought we might get a good thing going]]." Sue proceeds to voice what pretty much everyone is thinking with "[[LampshadeHanging For God's sake Johnny, you've known her for an hour!]]"
* Elizabeth and Anthony in ''ComicStrip/ForBetterOrForWorse''. It was bad enough that Elizabeth dumped two other boyfriends that she had better chemistry with for Anthony. It was worse that Anthony was still married when they got together for good. It was even worse when Anthony's ex-wife was villainized as a horrible woman for ''daring'' to avert StayInTheKitchen and suspecting that Anthony was cheating on her (Even though he ''was'', and even though he promised he'd be a HouseHusband when he convinced Therese to get pregnant, then went back on his word.) What probably puts it in this trope the most is how ''everyone'' talked up this pairing, from Elizabeth's parents to their mutual friends to ''the author'', with the only person with reservations being TheUnfavorite of Elizabeth's family. And don't even mention the "[[AttemptedRape going]] [[RapePortrayedAsRedemption after]]" if you want to avoid a FlameWar.
* Subverted in the ''ComicBook/InfiniteCrisis'' storyline "One Year Later". It had [[ComicBook/WonderWoman Diana]] suddenly involved in a relationship with Nemesis (Tom Tresser), a new co-worker and long-time minor DC character. Many fans felt this new hookup was rushed at best, especially since Tom was [[NotAsYouKnowThem considerably more boorish than in previous appearances]]. Eventually, in ''ComicBook/WonderWoman'' #32, it's revealed that Diana never had romantic feelings towards Tom at all; she was just exploiting his feelings towards her to get him to father her daughters and replenish the Amazon population. So, instead of her loving a jerk, she's a borderline sexual predator taking advantage of ''his'' feelings! What an impro-wait, what?
* In an oddly well done example, ComicBook/{{Mockingbird}} and Comicbook/{{Hawkeye}}, who got married literally a fortnight after meeting. The two realized they had chemistry after knowing each other for about a day (during which they spent most of bickering, though in an old married couple kind of way), and decided to get married as soon as possible. However, since they ''do'' have great chemistry, have similar personalities, and fighting styles which compliment the other, they work well together despite the questionable introduction and, while they're currently broken up and have had several falling outs and breakups, they remain one of Marvel's most popular pairs. Still, ComicBook/CaptainAmerica telling Clint that getting married to a girl he just met is ''the most responsible thing he ever did'' makes for a {{narm}}y moment.
* ''ComicBook/{{Runaways}}'':
** For most of the original series, Chase showed an obvious attraction to Karolina, completely oblivious to the signs that she was a lesbian, but suddenly fell in love with Gert after the latter saved his life.
** Karolina Dean and Xavin. The entire basis for their relationship was that she was a lonely, depressed teenage lesbian, and Xavin was able to become female, and also, they had an ArrangedMarriage that had to be consummated or else three different worlds would be destroyed, the result of Karolina's evil parents' machinations. That Karolina had a history of suicidal tendencies gave their relationship some UnfortunateImplications that Creator/BrianKVaughan apparently had no interest in averting (the little that is shown of Karolina's time among the Skrulls suggests that Xavin kept her completely isolated throughout their courtship). Even Creator/JossWhedon seemed to struggle to make their relationship look good before finally just making Xavin female. Later on, Creator/TerryMoore [[PutOnABus put Xavin on a bus]].
** Victor Mancha completely falling for a girl named Lillie the very same day he met her, even going so far to start having wet dreams about her, and cheating on his current girlfriend Nico the very next day. The fact that Nico herself pushed Victor to cheat on her and later justified it as they having discovered "true love" was way too much to swallow. Especially considering that original creator, Brian K. Vaughan, took a long time to develop Victor and Nico's relationship, from a mistake to a real bond of love, before leaving. What's worse, the girl doesn't even stay with him in the end, so the thing just ended up looking like a messy plan to break up Victor and Nico. Makes you wonder if Joss Whedon hated poor Victor or something.
* Marko and Alana of ''ComicBook/{{Saga}}'' are a great couple of characters in a stable relationship. It's downright bizarre that special agent Gale claims Marko was transferred to Alana's prison facility but within 12 hours she had helped him escape and they were on the run. Flashbacks nail down that there was zero chemistry when he called her to his cell (she hit him with her rifle butt to get him to stop yammering about conscientious objection). Shortly afterward she stole his translation rings out of lockup so she could read Heist's interracial romance novel to him. Sometime in the afternoon he revealed that he was being transferred to another prison and she broke him out.
* ''[[ComicBook/ArchieComicsSonicTheHedgehog Sonic the Hedgehog]]'':
** Antoine and Bunnie Rabbot were thrown together in one story with almost no build-up beyond the same issue they got together revealing that Antoine had once saved Bunnie's life. Thankfully, the relationship was well handled after that point, and it was easier to accept than most examples because neither of them had any romantic chemistry with other characters. The reboot kept them a couple, but handled it differently by giving them a relationship built on mutual support and inspiration.
** Worse off is the Echidna race - according to WordOfGod, echidnas have what is called "the Soultouch" - a sixth sense that also acts as a literal Red String for them and that once they've found their soul mate, they pretty much stay together, although there are some exceptions. This is why Knuckles and Julie-Su hooked up only after 24 issues and why he hasn't been broken up with her.
* ''ComicBook/SpiderMan''
** Following the much-loathed comic ''ComicBook/OneMoreDay'', (an event which nullified Peter Parker's 20-year marriage to Mary Jane) [[ExecutiveMeddling editor in chief]] of Marvel Creator/JoeQuesada's first order of business was to establish a new {{Love Interest|s}} for Peter, who just happened to be named after [[CreatorsPet Quesada's own daughter]]. Despite how much the readers hated [[RelationshipSue Carlie]], Quesada was so hellbent on setting her up to be Spidey's [[OneTruePairing true love]] that even Mary Jane herself was [[CharacterShilling supporting her on Quesada's behalf]].
** It happens again in the prelude to the ''ComicBook/SpiderVerse'' event, when Spider-Man starts a relationship with newcomer ComicBook/{{Silk}}. Thing is, their relationship only happens because of a pheromone that makes them crazy for one another. That means Spider-Man is being strangled, and Silk is the one pulling on the red string.
* Tim Drake ([[Comicbook/RobinSeries Robin]] III) and Cassie Sandsmark (ComicBook/WonderGirl II) from ''Comicbook/TeenTitans''. Given the fact that they had a very platonic interaction before the hookup, that Wonder Girl was the girlfriend of Robin's dead best friend ComicBook/{{Superboy}}, and the reason they kissed in the first place was due to mutual mourning of said person... yeah, it was definitely a trainwreck. Fans of both Wonder Girl and Robin sighed a collective breath of relief when the pairing ended.
* ''Comicbook/XMen'':
** Colossus' instant infatuation with Zsaji in ''ComicBook/SecretWars'' counts -- despite his long-established relationship with ComicBook/KittyPryde, he falls head over heels for the alien after she heals his injuries. Possibly justified by BeCarefulWhatYouWishFor, as some theorize that Zsaji was the Battleworld granting Colossus' wish for "the perfect girlfriend". It was also implied that Zsaji's healing powers also created some degree of emotional bond between her and the recipient. In RealLife, the reason for the instant romance was ExecutiveMeddling -- Creator/JimShooter, who wrote the story, was becoming increasingly concerned and alarmed at Creator/ChrisClaremont's romantic pairing of Colossus, who was 19-20 at the time, and Kitty Pryde, who was 14, especially after scenes where Kitty had offered herself out of despair sexually to Colossus (he refused) and where the two shared a kiss. He took the opportunity of ''ComicBook/SecretWars'' to completely and (he thought) irrevocably sink the Kitty/Colossus ship. It would not be raised until decades later, and both characters were of legal age.
** [[ComicBook/{{Cyclops}} Scott]] dating ComicBook/EmmaFrost. What's really bad is the excuse given for why they're dating so soon after ComicBook/{{Jean|Grey}}'s death is "not" a rebound relationship (Creator/GrantMorrison had them have an adulterous psychic affair before Jean's death, but realistically that was Emma - his supposed therapist - unethically taking advantage of him when he was vulnerable). As proof it was contrived, there is this BadFuture that Jean needed to avert. Going back in time, like ''every other'' such future, somehow wasn't an option. Instead the only options were: 1. Scott and Emma didn't get together, the X-Men would fall apart and things go all to holy hell. 2. Jean brainwashes her husband into forgetting his feelings for Jean and giving in to his attraction to Emma.
** ComicBook/BlackPanther and ComicBook/{{Storm}}'s marriage resulted from Reginald Hudlin's [[ProtectionFromEditors hamfisted railroading]] of the relationship from casual acquaintance to Wedding Of Perfect Couple as soon as possible, and were made out as some kind of First Couple of Black Superheroes. Subsequent writers were not subtle about their distaste for the pairing, and found any possible reason to have Storm go on missions with the X-Men or for T'Challa to have solo adventures. After the events of the ''X-Men vs Avengers'', where the two fought, their marriage has been annulled.[[note]]Their marriage in the older ''ComicBook/EarthX'' miniseries wasn't nearly as hated, since it took place in the future where Ororo and T'Challa presumably had a healthy romance before tying the knot. Storm even says at one point that he made her feel like a queen long before he made her one.[[/note]]
** Bobby Drake/Iceman and Kitty Pryde/Shadowcat. As of the seventh issue of the ''ComicBook/WolverineAndTheXMen'' comic, Bobby and Kitty have shared two kisses, despite how they've spent years as distant acquaintances at best. They had a decent relationship arc in the ComicBook/UltimateMarvel universe, and writers have been known to mix the two up before. It comes completely out of nowhere in the main Franchise/MarvelUniverse. However, this, too, was crashed into the ground, this time by the events of ''ComicBook/BattleOfTheAtom'' after Kitty gets fed up with Wolverine's HolierThanThou attitude and, after chewing out Iceman for not trying to stand up for himself and leaning towards Wolverine's way of thinking, breaks it off and goes to join Cyclops' team.
** Comicbook/{{X 23}} and Angel of the O5 getting together in ''Comicbook/AllNewXMen''. Despite having not interacted on-panel at all through the first two story arcs after Laura joins the team — and in fact, Laura having been {{Ship Tease}}d ''with an entirely different character altogether'' up to that point — Warren suddenly decides he's interested in her in the third. It comes so far out of left field that many fans are convinced that the romantic plot was meant for Laura and ''Scott'' (the character with whom she was being teased in the first two arcs), but some combination of ExecutiveMeddling and his leaving the book for the Cyclops series forced Bendis to revise the plan and he just picked a random member of the O5 who wasn't doing anything else important. Such views are only reinforced by accusations that Warren has become a SatelliteLoveInterest in the second volume, with everything about his character in the first few issues revolving around his relationship with Laura.
* During his run on ''ComicBook/TheAvengers'' writer Creator/JonathanHickman paired up his new character, Izzy "Smasher II" Kane and former [[Franchise/XMen X-Man]] and current Avenger, Cannonball. Up to that point, Avengers readers would be hard pressed to name a time the two had even talked to each other, let alone established a relationship. In the space of a couple of years, Smasher and Cannonball went from "Didn't know they knew each other's real names" during [[ComicBook/{{Infinity}} "The Builder Wars"]] to "they have a son together" by the time of [[ComicBook/SecretWars2015 "Time Runs Out."]]
* The ComicBook/UncannyAvengers run brought us Havok paired with ComicBook/TheWasp. After approximately three issues of flirting, readers were suddenly flung into a timeskip where they were married with a five-year-old daughter. And ''then'', after timey-wimey stuff caused said kid to get erased, everyone to get sent back to the present, and Alex to get turned evil, he ''kidnaps Jan to "make sure they get their daughter back"'', and nothing has been touched on either character in the current time since.
* ComicBook/TheAvengers #200 did this to such an amazingly offensive level that in a later comic, Chris Claremont had ComicBook/MsMarvel (the woman involved) deliver a WhatTheHellHero / TheReasonYouSuckSpeech to her fellow Avengers.
* During the ComicBook/{{New 52}} era, editors were that adamant on pairing Franchise/WonderWoman with Franchise/{{Superman}}, that they did not dig much deeper than the “same type of powers and colors pattern” gimmick. They had exactly ''one'' short and mundane exchange before dating without seduction period, while Wonder Woman dumped her ordinary, yet irreproachable usual boyfriend Steve Trevor with no explanation. Then the path to Superman and Diana’s rupture was full of petty arguments, proving they had not much in common, in fact. To make things even worse for Diana, Superman was as usual actually attracted to ComicBook/LoisLane but put it on hold as she was dating someone else when they met that time. In the subsequent continuity overhaul, ''Rebirth'', the situation came back to normal, as the pre-Flashpoint Superman took over and was married to Lois Lane. ''ComicBook/SupermanReborn'' went as far as to ''remove the entire Clark/Diana relationship from continuity''.
* From ''ComicBook/{{Hawkman}}'':
** Kendra Saunders with Carter Hall. It was seemingly meant to be a deconstruction of Hawkman and Hawkgirl's "eternal love", as Kendra was a reincarnation of Hawkgirl who not only didn't remember her previous lives, but also didn't have feelings for Carter, preferring a ScrewDestiny view of her fate. Meanwhile, ''he'' just... ''assumed'' they'd be together, because that's how it had always been! Kendra actually was in relationships with other characters, including a well-received one with Roy Harper. People generally preferred Hawkgirl this way, as a strong independent character. Meanwhile, Carter was very publicly projecting his expecations and feelings for Shiera onto Kendra, which she made clear she hated. Then she started showing some attraction to Carter because... reasons? Then taken to ridiculous lengths in ''ComicBook/BlackestNight'', where Carter casually insults and rebuffs his best friend in a JerkAss moment even for Carter, leading to Kendra [[MoodWhiplash immediately deciding how hard it is not to love him,]] just to satisfy the prophecy that they declare their love just before they die in each incarnation, as they die in that very same issue, Kendra's ''last words'' being a proclamation of love for Carter.
** Katar and Shayera ComicBook/PostCrisis. In ''Hawkworld'', he's a DefectorFromDecadence who is frustrated with his society's class system and his people's treatment of other races. So obviously he falls for... Shayera, who publicly torments a servant right in front of him and callously murders what she considers lesser life. There is actually ''zero'' reason given for his attraction to her, as it's made clear that her behaviour disgusts him. Unless he just thinks she's hot, but after her death, he plays it up as some significant relationship.
* ''ComicBook/TitansRebirth'' has quite a few in ''one issue'' no less. One issue focuses almost entirely on the romantic troubles of the team, like a love triangle between Wally West, Donna Troy and Roy Harper. Wally has shown ''zero'' feelings for Donna, but they end up making out because Linda Park "breaks up" with him (they weren't a proper couple anymore) and both understand what it's like to have messed up memories. Rushed, to say the least, but at least logical. The worse offender is Lilith and Garth, who get together because... no reason stated. And they've barely interacted before this issue. [[ShowDontTell But because Lilith is a psychic, she says she's known that Garth has been hiding his feelings for here]].
* From the ComicBook/DCRebirth relaunch:
** In general, it has quite a few because of its very nature. Because it's a return to DC's roots and a spiritual return to the pre-Flashpoint universe, it has a lot of characters that were FanPreferredCouple but weren't couples anymore (as a result of ''Flashpoint'') getting back together. The problem is that it rushes them quite a bit, because it assumes a level of familiarity from the reader.
** An example would be Green Arrow and Black Canary suddenly pining for each other after one meeting (where they didn't even speak) in ''DC Universe: Rebirth'' #1. Their relationship was expanded upon in the ''ComicBook/GreenArrowRebirth'' series where it made more sense, as the two actually got to know each other, at least.
** From that same issue, Wally West and Linda Park. It works a little better, since Wally explicitly remembers the timeline pre-Flashpoint (though Linda doesn't), but it's still weird for new readers who don't know about the two. He ''does'' explain why they fell in love, but it's a case of him telling not showing, as you just can't condense over a hundred issues into a single scene. This version of their relationship was also prevalent in ''ComicBook/TitansRebirth'', where it ended with the two never becoming a couple like Wally wanted. To say fans are not amused when it comes to the handling of ''the'' Flash couple is an understatement.
** Tim Drake and Stephanie Brown in ''ComicBook/DetectiveComicsRebirth'' suffered from the same problem as the above. Many don't like that Tim and Steph were depicted in a relationship together with no prior buildup. James Tynion assumes a lot of familiarity and fondness for the characters and their relationships from the pre-Flashpoint era, and as such ''lots'' of the relationships, romantic or not, come across as sudden. Tim and Steph are no exception. Tim's DyingDeclarationOfLove feels hollow for this reason, as does Steph's TheMourningAfter status.
* The page picture is from ''ComicBook/MsMarvel2014'' - it's a cover from an arc that promises romance between Kamala and another superhero, Red Dagger, who until this point had all of one, brief aperrance in the book. Apparently somebody knew how it's gonna feel to fans and decided to throw a bit of LampshadeHanging....

* The ''Literature/GossipGirl'' story "An Affair to Remember". It follows follows Nate and Jenny's storyline from season, but rather than develop it for a season like the show did, Nate is suddenly in love with Jenny to the point where Jenny is confused by it.
* In ''FanFic/AngelOfTheBat'', protagonist Cassandra Cain is only shown to be with her girlfriend Sadie (who had only had a few scenes beforehand) in the epilogue. WordOfGod is it's still early in their relationship and it's just puppy love, which works... Until the story's second epilogue that shows them getting engaged two years [[OffscreenRomance offscreen]] later. The writer admitted its canon status was sketchy and he mostly just wanted to celebrate the ban on same-sex marriage being unconstitutional. Despite all that, a later fic in the same universe do depict them happily married without much said about how they got there.
* Happens in the Literature/InheritanceCycle fanfic ''[[https://www.fanfiction.net/s/8631890/2/From-the-darkest-of-Shadow-a-Light-is-born From the darkest of Shadow, a Light is born]]'' between the main protagonist and [[spoiler:[[TykeBomb Elva]]]]. They go from just meeting each other for the first time in 11 years in one chapter, to attending a party together in the next, before then diving full into a relationship in the same chapter as the party. [[spoiler:The relationship equally quickly took a turn for the {{wo|manScorned}}rse with a RoaringRampageOfRevenge, quickly followed by the male protagonist.]] The use of a TimeSkip means there's 9 years of InnocentCohabitation between the first reunion and the time when the relationship became romantic, [[spoiler:and 12 years between the start of the relationship and the ''lovers' spat''.]]
* In ''Fanfic/KnowledgeIsPower'' Harry and Hermione have a soul bond that comes with dire consequences for anyone who messes with it, but aside from that we're [[ShowDontTell not shown why]] they're so good for each other.
* Link and Jenna's relationship in ''Fanfic/MyInnerLife''. Indeed the first words out of Link in the entire story are him calling Jenna beautiful and he asks her out on a date immediately after. Aside from some sex and a few mentions of being sad about Jenna having to leave there is absolutely nothing else between the two between their first date and Link proposing to her. Though the story frequently harps on how perfect the pair are for each other, there's pretty much no actual examples of why they are.
* Lightning Dawn and Starla Shine from ''Fanfic/MyLittleUnicorn'', who fall in love immediately for no reason besides that the main character needs a love interest. Ditto for Rhymey and Fluttershy, and The Grand Ruler and Princess Celestia.
* Pretty much all the couples in ''Fanfic/ThePrayerWarriors''. Perhaps the most notable is Jerry and Mary, who are introduced as a couple like this. ("We are not dating, in case you Satanic scum think there is something Satanic going on. We are dating, but...") Worse, the author apparently forgets who's paired with whom from time to time. For example, late in ''[[Literature/HarryPotter Battle with the Witches]]'', Draco and Ebony[[note]]Not the Ebony from ''My Immortal'', but you can be forgiven for thinking they're the same[[/note]] get married and consummate their relationship, but by the end, three chapters later, Draco is abruptly married to Hermione.
* In [[http://archiveofourown.org/works/224907/chapters/340216 this]] ''Literature/SherlockHolmes'' and ''Series/TheSentinel'' crossover, Holmes is a Sentinel, a type of human with superior strength and enhanced senses that needs to "bond" with an empathic Guide, such as Watson, to survive for any extended length of time, or else the sensory overload will drive him mad. While most of the time, a bonded pair knows each other for a while before they actually bond, there are instances where [[LoveatFirstSight spontaneous bonds]] occur, [[spoiler:such as theirs]].
* In ''Fanfic/TheElementsOfFriendship'', one common complaint is that Fluttershy and Rainbow Dash's romance came out of nowhere. This got an Author's Saving Throw where it's stated they got together quickly when [=NightMare=] Moon's reign started, and they decide to cancel their wedding.

[[folder:Film - Animated]]
* Franchise/DisneyAnimatedCanon:
** This is the case with earlier movies, particularly ones like ''Disney/{{Snow White|AndTheSevenDwarfs}}'', ''Disney/SleepingBeauty'' and ''Disney/{{Cinderella}}''. It can be chalked up to Creator/{{Disney}} trying to keep to the source material, which in those cases were mostly fairy tales meant to teach morality and not build a believable love story. Later movies fix this, by giving the couples more interaction and personalities beyond "She's the girl of my dreams!". Even in ''Disney/TheLittleMermaid'' the relationship of Ariel and Eric, occurred between two people who did not know each other for more than three days, and she couldn't even speak at first, yet after those three days they're already getting married.
** Simba and Nala from ''Disney/TheLionKing'', to some. As cubs they don't express any romantic interest in each other and are disgusted by their ArrangedMarriage. When they find each other again as adults they goof around for a little bit and fall in love within a night. Unless if you could argue that they [[SheIsNotMyGirlfriend simply denied their feelings as cubs]] and [[SheIsAllGrownUp only realized them when they were reunited as adults.]]
** A number of fans perceive Anna and Kristoff's relationship in ''Disney/{{Frozen}}'' as such. They do have a fair bit of interaction, but none of them, aside from the "Fixer Upper" song, can be perceived as ShipTease without some serious ShippingGoggles, especially since Anna was still engaged with Hans throughout those scenes, and didn't even realize that Kristoff has feelings for her until Olaf pointed it out in the finale. On the other hand, it's arguable that's the ''point''. Her attraction to Hans was also classically contrived, and we saw how ''that'' ended up. As of the end of the film, Anna and Kristoff are merely ''dating'', and they're actually taking their time to see where it goes. Of course, that doesn't stop ''Disney/FrozenFever'' and other works from treating their relationship as ''fait accompli''.
* In the rather forgettable ''WesternAnimation/TheInvincibleIronMan'' the romance between Tony and Li Mei suffers from this. Tony and Li Mei are supposed to be madly in love in spite of the fact they never have an actual conversation or ever really have any time together.
* ''WesternAnimation/StrangeMagic'': While the romance [[TheHero Marianne]] and [[EvilOverlord the Bog King]] happens in a course of a few hours, there's at least an attempt [[BelligerentSexualTension to explain how that happens]]. The really bad case of this is Dawn, who is broken out of the effects of a LovePotion when she has a LoveEpiphany that she loves [[DoggedNiceGuy Sunny]], even though she's showed no interest in him at all the entire film except as a friend.
* ''WesternAnimation/TheSwanPrincess'' clearly tried to avoid this, but didn't quite know how. Odette and Derek are [[ArrangedMarriage being pushed to marry]] from childhood, but grow up being {{Friendly Enem|y}}ies at best. Then they suddenly fall in love as adults upon [[ShesAllGrownUp seeing how good-looking the other is]]. The movie tries to {{deconstruct|edTrope}} this part--Odette actually [[ChildMarriageVeto calls off the engagement]] when Derek can't think of anything to compliment but her beauty--but once she gets captured by Rothbart the two act like they're engaged again, their conflict forgotten except for a throwaway line at the very end of the movie.
** Some viewers have theorised that [[AlternativeCharacterInterpretation the pair actually did grow to like each other]] and were in denial over their feelings until they both grew up. Despite alledgedly hating each other, they actually make an effort to spend time together (in particular Odette), some of their passive-aggressive behaviour could be interpreted as BelligerentSexualTension, Derek gets annoyed that she's flirting with castle guards (jealousy, perhaps?) and Brom outright tells teenage Derek that he thinks he likes her really. Of course, the film doesn't really explain this clearly so the aforementioned scene of them falling deeply in love upon sight comes across as a bit jarring.
* Done painfully in both ''WesternAnimation/TitanicTheLegendGoesOn'' and ''WesternAnimation/TheLegendOfTheTitanic''. The former involves the hero and heroine deciding they were made for each other... after sharing about three sentences. It becomes hilarious when we're shown flashbacks to their meetings... one of which was ''accidentally bumping into each other''. The latter plays this even worse, as the heroine's love interest realizes they are meant to be after ''sniffing her glove''.
* In ''WesternAnimation/JusticeLeagueCrisisOnTwoEarths'', new character Rose Wilson has a crush on ComicBook/MartianManhunter. The Martian inadvertently discovers they're "attuned" when he accidentally reads her thoughts (something he'd never do by accident with a non attuned person). He then Mind Melds with her so that they can get to know each other instantly and fall completely in love. Martians apparently have no need to date.
* ''WesternAnimation/{{Thumbelina}}'' has a definite example of this trope with respect to the main character and her love interest Prince Cornelius. They only spent one night together flying around in the starlit sky and singing about how much they loved each other. This is made even more poignant when you take into account that the night they did all that was the night they met for the very first time.
* Hiccup and Astrid's relationship in ''WesternAnimation/HowToTrainYourDragon'' can be seen as this. At the beginning, it is established that Hiccup has a crush on her, but Astrid spends the first half of the movie either completely ignoring Hiccup or being extremely rude to him, and right before meeting Toothless, she is about to beat him up. Then they go on a ride on Toothless' back and apparently that was all it took for Astrid to realize she likes him back.

[[folder:Film - Live Action]]
* Peter and Gwen in ''Film/TheAmazingSpiderMan'' start off not knowing each other personally and yet hook up in their second scene of extended interaction together, and stay a couple for the rest of the movie. This is fixed in [[Film/TheAmazingSpiderMan2 the sequel]], though, and thank goodness, as otherwise [[ILetGwenStacyDie the inevitable result of their relationship wouldn't have been as effective]].
* Pre-release, this was feared with the teasing of the Black Widow/Bruce Banner romance in ''Film/AvengersAgeOfUltron''. After release, given it's Widow's major story arc in the movie, both critics and fans were divided on how it was handled. A big factor in this is that at least an hour of footage was cut from the movie (which is ''still'' 2 1/2 hours long), which makes much of their romance (and the rest of the plot) seem to just lurch from event to event without any proper build-up.
* Creator/AdamSandler movies are ''very'' fond of this trope. For example, ''Film/BillyMadison'', where Veronica quite clearly finds Billy to be both obnoxious and a burden on her as a teacher. But then, during a field trip, she has a random MoodDissonance and is madly in love with him for the rest of the movie. All it took was [[spoiler:Billy faking his own pants incident to rescue another student from being shamed by his classmates. Nevermind that, just a few scenes back, Billy himself shamed another classmate by mocking him for struggling with a reading assignment]].
** PlayedForLaughs during ''Billy Madison'''s PairTheSpares sequence, as only one of the pairings had ''any'' form of buildup in the movie itself, while the final one [[spoiler: is between Creator/ChrisFarley's bus driver and the hallucinatory penguin]].
* ''Film/BramStokersDracula'' (1992) has this between {{Dracula}} and Mina. Despite how they don't know each other at all and Mina was engaged with the main character Jonathan, Mina continued to pine over Dracula, continued to calling Dracula "My Prince" even after she got married and seemed to try to foil the heroes' plan to destroy him at times. HypnotizeThePrincess is pretty much implied to be involved, since Dracula had already started biting her, and thus could easily have her under his spell. On Dracula's end, this is because Mina happened to look like Dracula's old love who committed suicide. Or is it that Mina was a reincarnation of said love? [[FridgeLogic This wouldn't make sense since the reason that Dracula became the Dracula is because he renounced God at the thought that his beloved will go to hell for committing suicide.]] [[YourHeadAsplode But then the ending showed that Dracula and his old love went to heaven]]. [[DrivenToMadness ARRRGHHH!!!!]]
* One recurring criticism of ''Film/CaptainAmericaCivilWar'' was the kiss between [[spoiler:Steve and Sharon]]. It's generally agreed by fans that their relationship has been badly handled by the writers, and their sudden RelationshipUpgrade mid-movie did nothing to win over even those viewers who were hoping to see them together. Between [[spoiler:Sharon]] being DemotedToExtra in her one previous appearance in the [[Franchise/MarvelCinematicUniverse MCU]], hence the build-up to their relationship being basically nonexistent aside from one vaguely flirtatious comment; and the fact that [[spoiler:Steve]] had learned only a few days before of the death of the previous love of his life - [[spoiler:Peggy]], who let's not forget was [[spoiler:Sharon's [[{{Squick}} close relative]]]] - it was a pretty unpopular move. Many comments were to the effect that it seemed tacked on just to get their relationship in the movies up to speed with the source comics, regardless of whether the timing was appropriate or whether [[spoiler:Sharon's]] character had been developed well enough up to that point.
* ''Film/{{Closer}}'' does this with its pairings, thanks to multiple [[TimeSkip times skips]] that don't fill in the blanks. Dan decides he's in love with Anna after one kiss. Anna gives Dan the brush-off. . .but the next scene has them confessing to their respective partners that they've been having an affair for over a year. Anna reassures Dan of her love for him despite having slept with Larry. . .the next scene reveals that she went back to Larry. Alice rebuffs Larry. . .but Larry is later seen taunting Dan about having slept with her. Dan is depressed over Anna leaving him. . .the next scene is of him and Alice in bed, having reconciled and all we get to explain this is a brief flashback of him tracking her down at the strip club. It gets jarring.
* ''{{Film/Enchanted}}'': The PairTheSpares is worse than other examples because it's a BrokenAesop. After mocking Love At First Sight for the whole movie, Nancy runs off with Edward to the animated world the same night that she meets him. It seems that true love ''does'' come as fast as fairy tales suggest it does, after all -- if you live in a Disney movie. It's more understandable if you see a deleted scene that paints Nancy as a jaded romanticist who's given up on meeting PrinceCharming but it's still jarring. Notice that the live action Giselle and Robert appear to spend weeks or even months together building their relationship and her career, while animated Nancy and Edward are getting married before her cell phone has completely run out of charge.
* ''Film/FourWeddingsAndAFuneral''. Charles and Carrie sleep together after the first wedding. The next time they see each other is at the second wedding, three months later, when they have sex again, despite her now being engaged. Several more months go by before their next encounter, probably the first thing close to a proper date that they've had, even though he's helping her choose a wedding dress--and this is when he declares his love for her. There's zero interaction between them at the third wedding (hers), a brief one at the funeral, and when she shows up at the fourth wedding (his), despite there having been sufficient time for him to get over her (ten months), he ditches his fianceé at the altar. That's a total of FIVE times he's ever laid eyes on this woman, but it's enough for to decide that he wants to spend the rest of his life with her.
* The ''Film/HarryPotter'' films, mainly due to their being {{Compressed Adaptation}}s, definitely lean towards the asphyxiatory side of things in regards to Harry and Ginny. The two barely interact, sharing the screen for about seven minutes combined in the last ''three movies''. In the [[Literature/HarryPotterAndTheOrderOfThePhoenix fifth book]], Ginny [[ShrinkingViolet being able to speak to Harry]] was a big deal; in the [[Film/HarryPotterAndTheOrderOfThePhoenix fifth movie]], Creator/BonnieWright barely has any lines. Whenever they are on screen together, they barely talk, instead just sharing a kiss and an awkward look before Harry rushes off to do something and Ginny sits down to be irrelevant to the plot.
* In the [[TheFilmOfTheBook film adaptation]] of ''Film/IAmNumberFour'', it's explained that the alien race ''works like this'', with your first love being for life. Number Four falls in love with Sarah within two days and apparently ''permanently.'' There's a long scene of overly-flowery declarations of love delivered in a manner that would make ''[[Franchise/StarWars Padme and Anakin]]'' cringe. It's telling about this trope in general: apparently, the creators considered the way romance works in movies to be so nonsensical that it needed to be [[HandWave handwaved]] with BizarreAlienBiology... yet so obligatory that saying "no, they can have the first date at the end of this movie and be the love of each other's lives by movie three" wasn't an option.
* On top of ''{{Film/Immortals}}''', [[SadlyMythtaken ahem, inaccuracies]], we have the "relationship" between Theseus and the oracle. Summary? Oracle predicts Theseus's actions. She fawns over him pointlessly. They do it. End.
* ''Indochine'': Camille falls in love with a French Navy officer right after he shoots a runaway prisoner right in front of her. No tension or buildup whatsoever.
* Nearly ''every'' Film/JamesBond film has Bond and the Bond Girl barely interact before they become a couple, and even in the cases where they do get some interaction (for example [[Film/{{Goldfinger}} Pussy Galore]] and [[Film/TomorrowNeverDies Wai Lin]]) none of it is romantic, with the only real exception being ''Film/OnHerMajestysSecretService'' and ''Film/CasinoRoyale2006'' . It's especially bad in ''Film/TheWorldIsNotEnough'', where Bond and Dr. Christmas Jones have absolutely zero romantic interaction or flirtation before he beds her at the end of the film. [[Literature/JamesBond In the novels]] this makes much more sense, as Bond is a philanderer and pretty misogynistic on top of it, rarely feeling much for the women he has sex with; the problem is that the films keep trying to present meaningless flings as genuine romances.
* In the 2003 Australian film ''Japanese Story'' Sandy goes from hating Hiromitsu to sleeping with him in the next scene with absolutely ''no explanation whatsoever''. [[spoiler:Soon after, he dies because of a diving accident and the rest of the movie is about Sandy being in deep mourning over a one-night stand.]]
* ''Film/TheLordOfTheRings: The Return Of The King'' (the theater release, anyway) has this between Faramir and Éowyn. It's elaborated on in [[Literature/TheLordOfTheRings the book]], but in the unextended movie version it's all rather sudden... Thankfully the filmmakers chose to play it subtle, so it's not ''as'' bad as other examples here.
* ''Franchise/TheMatrix'' films do this with Neo and Trinity. They know each other for a few days and barely interact. When they do interact, they talk about kung-fu and machines. Then at the very end of [[Film/TheMatrix the first movie]], she spontaneously declares her love for Neo despite no build-up, other than a DeusExMachina, earlier in the movie about the Oracle's prediction.
* Brian and Judith in ''Film/MontyPythonsLifeOfBrian''. Brian finds her attractive, and Judith is upset when he is captured by the Romans, but not in a way that implies that she sees him as something more than a fellow rebel. Then they meet in the desert, and [[SexyDiscretionShot the next shot]] is them waking up in bed together.
* Oscar and Theodora in ''Film/OzTheGreatAndPowerful''. A major part of the movie's plot revolves around her falling in love with him, and then [[spoiler: turning evil after she thinks he's betrayed her]]. But this falls short when you realize that Oscar and Theodora have only known each other for a day or two before he leaves the Emerald City and they don't see each other again [[spoiler: until after her FaceHeelTurn]]. Despite this, she's already talking about how she'll be his queen and they'll rule Oz together, and completely breaks down when she thinks he's cheating on her. It's also not entirely clear how far their relationship went to begin with and whether they actually slept together or not, which can make Theodora come off as a ClingyJealousGirl or a StalkerWithACrush.
* Parodied in the ending of ''Film/ThePirateMovie'', when Mabel arbitrarily grabs Pirates and Daughters and throws them together, with even the last two male pirates getting [[PairTheSpares stuck together]] with suitably shocked expressions.
* In ''Film/{{Pixels}}'', Violet falls in love with the main character Sam Brenner, despite him acting like a creep (checking her out when he's supposed to do his job, making comments about her masturbating) and being a loser. It's also fairly abrupt how fast she goes from hating him to being willing to talk about personal issues like her recent divorce.
* In ''Film/PrinceCaspian'', Caspian and Susan [[PromotedToLoveInterest become a couple]] for five minutes at the end of the movie because [[RescueRomance he rescued her once from some soldiers]]. Suddenly at the end the two are snogging in front of a crowd, only for their relationship to end five seconds later when Susan and her siblings return through the portal to England, meaning she and Caspian will never see each other again. Thus, there was no reason to include their romance in the first place because it was doomed to end anyway.
* In ''Film/PrinceOfPersiaTheSandsOfTime'', Dastan and Tamina have the whole movie to slowly bond with each other, get into playful arguments and display plenty of BelligerentSexualTension. This seems to be one of the good things as their chemistry and the buildup feels natural... But their FirstKiss comes at the ''worst'' possible time: right after violently dispatching the BigBad's [[TheDragon dragon]].
* Being a loving sendup of swashbuckler stories, ''Film/ThePrincessBride'' has this going on with Buttercup and Westley. Almost all of their relationship development happens in the prologue, when Buttercup realizes that the local farmboy is in love with her, and then they kiss. In the rest of the movie, they're separated for all but two scenes (and they spend most of those scenes bickering), and the entire plot is driven by their true love and their need to be back together. This is pretty much in-line with how the genre tends to have the audience TakeOurWordForIt that the DistressedDamsel is the hero's true love and primary motivation, further suggested in that Westley and Buttercup exclusively [[BeautyEqualsGoodness describe each other's physical appearance]] when speaking of each other. Weirdly, the actors are so passionate and sincere that they mostly manage to sell the romance anyway.
* ''Film/{{Replicant}}'': The innocent clone eventually fakes his own death and starts a new life with a HookerWithAHeartOfGold he had met for only a few minutes.
* Deconstructed in ''{{Film/Rush|2013}}'': [[TheCasanova James Hunt's]] resolve to "marry a good woman and form a stable relationship" results in him marrying a British model Suzy Miller ''one scene'' after their initial interaction. Hunt's unsuccessful UsefulNotes/FormulaOne career in 1975 and his team's bankruptcy cause him to throw a tantrum, yelling at his wife and ultimately leading her to desert him through sheer frustration. This marks them as an unideal couple compared to [[HappilyMarried the stable and understanding Niki and Marlene Lauda]], whose developments and dramas are shown throughout the last third of the film.
* ''Film/SlumdogMillionaire'': Jamal is in love with Latika and literally risks his life to find her because... they were friends as kids? Granted, they went through some very rough stuff together, but it's entirely possible for two kids to go through a bad time and not fall in love. The presence of the trope is only confirmed by the movie's explanation for their ending up together: "It is written". They're together because they HAVE TO BE, OK?
* ''Film/{{Speed}}'': Jack (Creator/KeanuReeves) and Annie (Creator/SandraBullock). After knowing each other for all of a few hours, they're making out and about to have sex in a wrecked subway car in the middle of a street with a [[ConcertKiss crowd of people watching]]. [[JustifiedTrope Justified]] and TruthInTelevision; people bond over traumatic experiences quickly. Amusingly enough, thanks to Keanu Reeves refusing to do the sequel it turns out they really didn't last long. They both {{lampshade|Hanging}} this.
-->'''Jack:''' I have to warn you, [[MeaningfulEcho I've heard relationships based on intense experiences never work]].\\
'''Annie:''' OK. We'll have to base it on sex then.
* ''Franchise/StarWars'': In the prequel trilogy [[ForegoneConclusion the audience already knows]] from [[Film/ANewHope the]] [[Film/TheEmpireStrikesBack original]] [[Film/ReturnOfTheJedi trilogy]] that Anakin and Padme are supposed to end up together to have Luke and Leia. Apparently Creator/GeorgeLucas thought this was enough and that their relationship didn't actually need to be convincing. Without the original trilogy, they fall headfirst into this trope.
** In ''Film/ThePhantomMenace'', the two do interact on Tatooine, and it's made clear that Anakin is attracted to her when he asks if she's an angel, but given that he's nine years old it comes off as a PrecociousCrush. After leaving Tattoine, the ''only'' interaction the two are shown having is a brief scene on Coruscant where they exchange a few lines of dialogue, and he ''doesn't even know it's her''.
** Immediately upon his introduction in ''Film/AttackOfTheClones'', despite having not seen or talked to Padme for the past ''ten years'', he's showing near stalker-esque levels of attraction to her, saying how he's dreamed about her every night for the past ten years and how "just being around her again is intoxicating". Their romance [[RomanticPlotTumor dominates the movie]] and distracts from the more important war and political aspects due to the completely unnecessary decision for it to be a [[ForbiddenFruit Forbidden Love]] story (despite the original trilogy and Episode I making no mention of it being forbidden for Jedi to be in relationships). And Padme does a complete 180 from "We can't be together" to "Let's be together", with the only important conversation they had in the interim being Anakin confessing that he ''murdered children''.
** In ''Film/RevengeOfTheSith'' their relationship is confined to the two declaring how much they love each other in the most cringe-worthy ways, and Anakin deciding that Padme is worth turning to TheDarkSide, killing Jedi Padawans (the guy just likes killing children), and bringing about the collapse of the Republic and replacing it with an oppressive dictatorship. The {{novelization}} handles this a lot better, presenting Anakin as obsessive and possessive, his actions less about his feelings towards Padme and more about his own desires. As The Distressed Watcher put it:
-->His single-minded objective is to prevent his dream from occurring, no matter what the cost. For this weak motivation, he betrays the Jedi, slaughters children, tries to kill his friend and mentor, Obi-Wan Kenobi, ends democracy so that Palpatine can begin a galactic empire... all of this because of a couple of nightmares. All of this to save someone for whom his love is not even very convincing.
* In ''Film/TheTerminator'', Reese claims to have been in love with Sarah ever since seeing her picture. Sarah is suspicious of him at first, but comes to trust him. Then, thanks to the fast pacing of the movie, [[CoitusEnsues they suddenly have sex]], followed by them being too busy fighting the Terminator to develop their relationship for the rest of the movie. At the end, Sarah says in a recording she's making for her son that she and Reese "loved a lifetime's worth".
* In ''Film/{{Thor}}'', this seems to be a widely held opinion on the romance between Thor (Creator/ChrisHemsworth) and Jane Foster (Creator/NataliePortman), which really only serves to give Thor a reason to want to get back to Earth. Some have even labeled it a RomanticPlotTumor, which is kind of funny considering that the same thing was said about Portman's character in the ''Franchise/StarWars'' prequels. Creator/KennethBranagh must have realized this and says in the DVDCommentary that their relationship wasn't meant to be true love, but more a mutual crush and respect. It gets worse in ''Film/ThorTheDarkWorld''. They've been pining for each other for the ''two whole years'' since. Once reunited, this movie proceeds to pretend they were madly in love throughout the last and their SickeninglySweethearts interaction is ''incredibly'' jarring when they've never been ''anything'' like that before. Part of one of {{The Stinger}}s at the end even starts with Jane looking all miserable ''again'' as if two days without him is hell on earth.
* InUniverse example. This is pretty much the point of the movie ''Film/{{Timer}}''. Once you meet your soulmate via Timer, you know you're going to end up with them eventually. Even if you love someone else right now, or are fourteen years old.
* ''Film/{{Underworld}}'' (2003): There is never any indication that Selene feels any real emotion toward Michael; they don't have any sort of conversation with each other about anything apart from vampires and werewolves, and they have known each other for a total of about two days. WordOfGod says this was the way it was supposed to be; special features on the DVD reveal that the two characters were not supposed to actually be "in love," but rather attracted to each other based on lust, confused feelings, and being forced together.
* In ''Film/TheWholeNineYards'', protagonist Oz meets Cynthia for about five minutes, she later comes to his hotel room, and after spending the evening together sharing stories, CoitusEnsues. The next day Oz flies home, several days later Cynthia arrives, and later that night he's proclaiming he loves her, to her ex-husband no less. The relationship between the ex-husband and [[spoiler:Jill]] is a bit better--those several days between Oz flying home and Cynthia arriving, the two of them also swap stories and he trains her, and she's a fan of his who idolizes him and has followed his work for years. By the end of the film it's just attraction they share, though years later in the sequel they're married.
* In the ''VideoGame/WingCommander'' series of games, the relationship between Blair and Angel is built up slowly and believably. In [[Film/WingCommander the film]]... it wasn't.
* In ''Film/TheWolverine'', Logan constantly dreams about Jean Grey and wishes to be with her again yet he shares a few intimate moments with Mariko, who's already engaged to another man at the time and has only known Logan for a few days. The film noir setting could justify this relationship as a form of comfort for Logan. It's worth noting that Wolverine also only knew Jean Grey ''for a few days at most'' [[note]](the first X-Men film takes place over maybe two days, then Wolverine goes to Canada to look around the Alkali Lake facility; in X2 he sees Jean at the mansion for a couple of minutes, and then meets up with her again the evening before the big battle; then they see each other on a couple occasions in X3 when she's the Phoenix)[[/note]] and, more importantly, ''they weren't actually in a relationship''. And that one's played as a romance for the ages.
* ''Film/{{Zardoz}}'' has [[Creator/SeanConnery Zed]] hooking up with [[StrawFeminist Consuella]], instead of May, in the end, even [[spoiler:having a son with her]], despite the fact that she literally spends the entire movie demanding that Zed gets eliminated. Then again, the whole film is such a MindScrew, and the [[GainaxEnding ending so bizarre]] that it hardly matters by that point.

* In ''Literature/ABrothersPrice'', Jerin's romance with [[spoiler:Lylia]] ensues quite suddenly. Justified in that they're both {{Hormone Addled Teenager}}a, and [[spoiler:as he falls in love with [[ExoticExtendedMarriage all the five eldest brides]]]] there would be no time to develop all those relationships in detail. And the narration doesn't claim it's true love, it is just portrayed as a mutual attraction.
* At the end of ''Literature/TheAccursed'', [[spoiler:Annabel]] is rather abruptly said to have fallen in love with the minor character Yaeger Ruggles, and they celebrate a double wedding with [[spoiler: Josiah and Wilhelmina]]. Especially awkward given that [[spoiler:Annabel]] never shows any inclination towards romantic love throughout the novel (except when she is [[spoiler:mind-controlled by [[OurDemonsAreDifferent the Count]]]]), and in fact seems pretty opposed to the idea of being in a romantic relationship. Of course, given that the entire novel is a bit of a MindScrew, the forced nature of this ending may well be intentional.
* One of the major point of contention among Creator/AgathaChristie's readers is that the romantic development between the two characters she pairs up are rarely believable.
** In ''The Man in Brown Suit'', Anne Bedingsfield saved a strange young man from a murderer, then got into a heated fight with him he proved most ungrateful. When Anne retells this story to a friend a day later, she expressed how passionately in love she is with him, and how she's willing to do anything for him.
** ''Literature/TowardsZero'' has [[spoiler:Audrey Strange and Andrew [=MacWhrter=]]] planning to get married after knowing each other for less than a week, with only one on-screen interaction.
* Dagny and John from ''Literature/AtlasShrugged''. [[Creator/AynRand Ms. Rand]] spends literally hundreds of pages carefully and painstakingly building up the relationship between Dagny and Hank, only to have her casually toss him aside when she meets John, who is [[RelationshipSue her One True Love]].
* At the end of ''Literature/{{Discworld}}: Discworld/ThiefOfTime'', Susan Sto Helit and [[spoiler:Lobsang Ludd]] begin to talk as though they have mutual feelings for each other, and (it's implied) begin a romantic relationship. However, there has been nothing vaguely romantic in their interactions up to that point -- which is odd, because there was a blossoming awkward romance between Jeremy and Myria[[spoiler:/Unity]], and Susan was quite taken with the idea of "someone like her" throughout the book.
* ''Literature/TheDresdenFiles'':
** In the short story "Love Hurts", Harry Dresden and Karrin Murphy (who are good friends) investigate a double murder where the victim and perpetrators had this trope happen due to mind control magic. Later in the story, they also find this happening to themselves.
** More subtly, the main novels have a brief story arc where [[spoiler:Anastasia Luccio]] falls in love with and starts dating Harry. At the end of "Turn Coat", we find this trope applies to poor Harry's love with that woman, because of [[spoiler:a conspiracy to weaken the White Council through mind control]] so it makes perfect sense. So the Red String had a good an in-universe reason. They break off the relationship simply because fate/magic was part of it, and trying to figure out how much was giving them both headaches and kind of freaking them out.
* The general pattern of romance in the ''Literature/EndersGame'' series is: "one character suddenly thinks it's fate to marry another character they barely know, the other character thinks they're rude, and suddenly they're married."
** Ender and Novinia in ''Literature/SpeakerForTheDead''. Ender feels a kinship with a teenage Novinia he has never met, but when they meet in person, she is a bitter woman in her late 30s and everything Ender does enrages her. In the concluding chapter, they get married. Made worse in ''Literature/{{Xenocide}}'', where the couple is seen 30 years later after they have drifted apart. She then [[spoiler:leaves him to move into a monastery]]. We never see them interact in any way that suggests that they actually like each other.
** Bean and Petra's relationship in the ''Literature/EndersShadow'' side series [[ShowDontTell relies more on exposition than on action]]. In the previous book, their interactions are akin to brother and sister, with Petra being rather bossy toward him and Bean trying to prove he can take care of himself. In the second book, Petra comes to realize (via internal monologue) that she likes Bean, but at that point in the book she hasn't seen him for about a year and merely has a vague hope he might be coming to rescue her. In the third book, she suddenly gets really desperate to have his kids [[spoiler:because he's got a condition that will spell his death by his late teens]] and we don't see much reason why Bean is any interested in her. Then when the two are separated forever, she suddenly finds out Peter is in love with her and the story flashes-forward to them married for no reason other than keeping her married at the end. Worse is that both marriages came at the expense of [[ShipSinking sinking the fairly popular ship]] of Petra and Dink Meeker from the first book, which ends up just getting a paragraph of exposition about how the two drifted apart.
** In ''Xenocide'', Wang-Mu idolizes the long-dead-by-''millennia'' Hegemon Peter and at the end of the book gets the unexpected offer to embark on an adventure with a clone of him. Over the course of three days she grows jealous of the AI he communicates with, even though said AI's life is on the line. She also doesn't pay much attention to the Peter clone admitting at the start that he's not actually like the long-deceased Peter and more akin to a {{Flanderiz|ation}}ed version with exaggerated ambition and sociopathy.
* In ''Literature/FiftyShadesOfGrey'', Anastasia and Christian barely like each other and can hardly have a civil conversation, yet we're supposed to buy that they can't live without each other.
* Nearly every romance in ''Literature/GauntsGhosts'' has no buildup or development whatsoever; the only exception is Caffran/Criid, and their buildup largely consisted of the two almost killing each other. Probably intentional, as it's implied that the characters don't have particularly strong feelings for each other and are just finding comfort where they can [[LikeYouWereDying because they know they could die soon]].
* The romantic storyline between Karigan and Zachary in ''Literature/GreenRider'' can come off a bit like this. Most of the first book is made up of Karigan just trying to reach the capital city. They interact a fair bit in the rest of the book and sporadically over the course of the series, but with the exception of maybe one conversation, all their talk is business rather than conversational or personal. Though an attraction between them is understandable (they're both rather impressive), it's easy not to see a 'chemistry' (let alone a relationship) when they only ever talk to each other like business colleagues, and spend far more time thinking about how much they love each other than they do in each others' actual company.
* ''Literature/HarryPotter'':
** Whether or not the books did this with the Harry/Ginny pairing is a [[BrokenBase major point of debate]] for fans of the series. Ginny starts off as a ShrinkingViolet fangirl but evolves into a hotheaded ActionGirl while OutOfFocus, with a lot of CharacterShilling done to make her look better. Harry becomes closer to and gains a romantic interest in her over the course of two summers which are never properly fleshed out so the development can look rather forced or random to readers.
** Lupin and Tonks. In ''[[Literature/HarryPotterAndTheHalfBloodPrince The Half-Blood Prince]]'', Harry sees Tonks upset several times and thinks it's [[spoiler:over Sirius dying]], and that maybe she was even [[KissingCousins in love with him]]. Then the climax reveals that Tonks is deeply in love with and wants to marry Lupin. They proceed to do so despite having no interaction on camera before this. As the books are primarily written from Harry's perspective, it's somewhat understandable that plenty of major events can happen off-camera simply because Harry can't be present for every single storyline. At the same time, the reader can still feel left out as the key parts of the RomanceArc never actually happen in front of ''them'' either.
** Happens InUniverse in ''Literature/HarryPotterAndTheHalfBloodPrince'' when Ron consumes a love potion from Romilda Vane, who he has never met, that was intended for Harry.
* In the second ''Literature/HellsGate'' book, two secondary characters are thrown together by their psionic powers the first time they meet. Literally the first words either says to the other are "Oh dear. This is an unexpected complication."
* In the ''Literature/HeraldsOfValdemar'' series, there's an InUniverse mechanism for this in the form of lifebonds, magical or divinely-caused compulsions that cause the lifebonded individuals to fall in love and also to share [[MindlinkMates an emotional link]]. As the series goes on, the concept is increasingly deconstructed: ''Winds of Fury'' contains an entire scene in which the spirit of Bard Stefen[[note]]Vanyel's lifebonded partner from The Literature/LastHeraldMageTrilogy[[/note]] explains to the trilogy's BetaCouple his well-supported theory that lifebonding primarily occurs between someone very powerful but emotionally unstable and someone more steady who can provide their lifebonded partner with the emotional grounding and stability they desperately need to keep them sane. As Stef advises from personal experience, the fact that one half of a lifebond is likely to be incredibly broken, this generally leads to an intense and angsty relationship ''far'' from the ultimate ideal of romantic love that many people in the setting mistakenly make lifebonds out to be. In the next trilogy, another character's obsession with forming a lifebond is rightfully presented as unhealthy and makes other characters uncomfortable; the general impression created by the narrative is that lifebonds are less about the depth of a couple's feelings for each other and more a case of BecauseDestinySaysSo which the vast majority of people are quite fine without, thank you.
* ''Literature/HonorHarrington'': The romance between [[AllAmazonsWantHercules Lara and Saburo]] in ''Crown of the Slaves'' started more or less like this:
-->'''Lara:''': Hi, I'm Lara, do you have a girlfriend?
-->'''Saburo''': No, why?
-->'''Lara''': Because now you have.
* ''Literature/HushHush'':
** Patch and Nora. Nora is warned by people who care about her to stay away from him, because he's clearly not a good person in any way, shape, or form. Patch stalks Nora, intentionally scares her, sexually harasses her, [[spoiler:{{mind rape}}s her, and possesses her body]]. On top of that, his ''original'' plan was [[spoiler:to murder her in cold blood]], which he flat out ''tells her'' -- and, when she asks if he's going to do it, he admits that it's "tempting". Nora says, more than once, that she sees absolutely nothing good about Patch. Wait, why does she fall in love with him again?
** Vee gets this when she hooks up with Rixon in ''Crescendo''. The two are hardly shown together and for all Vee fawns over him as the "perfect" boyfriend, there's precious little on them actually having anything in common. Vee repeatedly states that she thinks that Patch is a jerk and a potential murderer but isn't the least bit concerned about the fact that ''he'' introduced her to Rixon (and that Rixon is Patch's best and possibly only friend). Vee seems quite certain that he's a "boyscout", despite that he more or less lives in a very nasty bar and is not exactly shy about dropping crude innuendos towards Nora. That could be chalked up to Vee being a HorribleJudgeOfCharacter, except that Nora also thinks that Rixon is "cool" and sees no problem with them dating, even though she knows that Rixon is a fallen angel who possesses a Nephilim for two weeks out of every year for sex (with said Nephilim [[AndIMustScream being conscious for it all]]). [[spoiler:The fact that Patch hooked Rixon up with Vee as a response to suspecting that Rixon was murderous just raises even more eyebrows.]]
* Deconstructed in Creator/BarbaraHambly's novel ''Literature/TheLadiesOfMandrigyn''. [[spoiler:Fawn, after taking off with Starhawk to try to find Sun Wolf, cuts out to marry Orris Farstep. She makes it clear that it's still Sun Wolf, not Orris, she loves; it's just that she knows that it wouldn't work out with Sun Wolf, while it ''could'' with Orris.]]
* ''The Magicians and Mrs Quent'' -- Ivy's marriage to Mr. Quent is a textbook example. The first half of the book is taken up by a RomanticPlotTumor between Ivy and Mr. Rafferdy, which took time to develop their characters; then, Ivy meets Mr. Quent, hates him, argues with him, and all of a sudden they decide they love each other and get married. Apparently he's "right for her" in a way that Rafferdy never was, for reasons completely lost on the reader.
* The ''Literature/MalazanBookOfTheFallen'' is ''quite'' bad at this. Characters will be madly in love after having only known each other for a few days, or after only a few brief meetings. Unfortunately, this more often than not leaves the reader somewhat confused. A few examples among the main cast include:
** In ''Literature/GardensOfTheMoon'', Ganoes Paran and Tattersail go from having known each other for a few days, the majority of which Paran was unconscious, to having passionate sex. Then Tattersail [[spoiler:goes off and dies]], and Paran spends the next two books pining after her.
** The same book has Crokus Younghand and Apsalar, [[spoiler:aka Sorry]]. They meet, have a few awkward conversations, and then Crokus is ready to leave his whole life behind to help Apsalar go back home. It develops into a case of RomanticPlotTumor, where until the end of the series it is not clear why or how they are in love -- they just are.
** The third volume, ''Literature/MemoriesOfIce'', has Sergeant Whiskeyjack (a human man) and Korlat (a millenia old Tiste Andii), who fall in love and hook up without any explanation after meeting for the first time.
** ''Literature/MidnightTides'', the fifth volume, gives us Trull Sengar and Seren Pedac. They meet about twice, for a few minutes each time, and then Trull does the Tiste Edur equivalent of proposing to her. She accepts, despite the fact that they know almost nothing about each other and have barely had a conversation between them. [[spoiler: An explanation ''can'' be found if one accepts that Seren is a latent mage and manipulates people's minds without being aware of it -- and she admits to herself upon seeing Trull for the first time that she is attracted to him.]] However, even that is barely implied.
** ''Literature/ReapersGale'' has Tehol Beddict and Janath Anar, who used to be Tehol's university professor. The fact that they know each other is not even mentioned until Bugg brings Janath home, and even then, all they do is bicker. By the next time they appear, in ''Dust of Dreams'', they are married.
** Speaking of ''Dust of Dreams'', the ninth volume, there's Brys Beddict and Aranict, who at least admits to only have joined the army because she lusted after Brys. However, they share maybe two conversations during the entire book, in one of which Aranict flat-out faints. By the next book, they are a couple and deeply in love.
** The same book has Henar Vygulf and Lostara Yil, the latter barely recovering from her previous strangled by the red string encounter with the assassin Pearl, who are instantly in love after their first meeting. So in love, in fact, that Lostara does a Shadow Dance to protect Vygulf when he's in danger, something she's never done before in the series. A damn god even comments about how much in love they are. It's especially jarring since, by their own admissions, they know almost nothing about each other.
* ''Literature/MaximumRide'' started out with just the gentlest of implied romance between Max and Fang, focusing mainly on an intricate plot revolving around the {{mad scientist}}s who created them. Then ''The Final Warning'' hit, the plot disappeared, and suddenly they were all over each other, [[RomanticPlotTumor all the time]]. The fandom was thrilled for the most part... except for those who [[FridgeLogic realized]] that these two characters were, for all intents and purposes, brother and sister...
* Done quite intentionally in the ''Literature/NightWorld'' series. Everyone has a soulmate, and you are meant for each other, [[BecauseDestinySaysSo no debate]]. The first book actually gives us two characters who have been friends for a while and been mutually building a relationship, but later books give us characters who {{deconstruct|edTrope}} and {{reconstruct|ion}} the idea of soulmates: [[BelligerentSexualTension Ash and Mary-Lynette,]] for example, act completely out of character around each other... because the feelings are entirely new and spontaneous towards a ''stranger''. [[spoiler:They get over it, mostly. And Ash becomes TheAtoner so he can deserve her.]]
* Beka and [[spoiler:Farmer]] from ''Literature/ProvostsDog''. About 400 pages of no romantic hints... and then suddenly she notices what broad shoulders he has. And then [[spoiler:they're declaring their love for each other and promising marriage while they're in a jail cell, after being tortured, and at a time when Beka ''still'' doesn't know for sure who the group traitor is]].
* Played with in-universe for ''Literature/TheRavenCycle'' heroine Blue. Growing up in a family full of psychics, she's been told the same prophecy about her true love for years. She gets pretty sick of it to the point that when she does meet the person who's supposedly her true love, she basically says ScrewDestiny and decides to pursue the boy she actually likes instead. [[spoiler:Not that this works out entirely, but she gets points for trying.]]
* Zayn second relationship in Katharine Kerr's ''Snare''. The other, presumably main, relationship Zayn had got pages and pages of mutual attraction and affection before they hooked up, spread over several weeks. This one had a bare paragraph explaining (not showing, explaining) that they were now friends. Next thing you know someone suggests that they're in love. Zayn is initially horrified, and is rather surprised at the whole concept of homosexuality. A few days later, yep, confirmed, they're in love.
* Moon and BZ Guindhalinu in ''Literature/TheSnowQueenSeries''. In ''The Snow Queen'', Moon goes through a lot of travails to find and rescue her childhood sweetheart Sparks. During her journey, she is captured and imprisoned with another man, BZ, who comes to fall in love with her. After they escape, Moon and BZ sleep with each other once, which cements BZ's love for her, but her heart still belongs to Sparks. At book's end, Sparks is rescued and BZ leaves the planet, believing he can never return to his true love ever again. Then, come the sequel ''The Summer Queen'', Moon is shown pining after BZ based on their ''single moment of sleeping together''. The vast majority of the ''950-page book'' is spent showing BZ and Moon pining, reuniting, and forming a romantic relationship that, as far as readers can tell, exists solely because they are good in bed. Other characters over the course of the series fall in love at the drop of a hat because of good looks and/or good sex, but to watch the main characters fall in love without any good rationalization outside of "We once had hot passionate sex 18+ years ago" is infuriating.
* The ''Literature/{{Stardoc}}'' series has [[spoiler:Cherijo and Duncan, Dhreen and Ilona, and Squilyp and Garphawayn]]; ''Blade Dancer'' has [[spoiler:Jory and Kol]].
* ''Literature/SweetValleyHigh'':
** In spin-off ''Sweet Valley Confidential'', Elizabeth is estranged from her family after discovering that Jessica and Todd were having an affair behind her back. In the original books, what was considered canon [[CanonDiscontinuity varied]] due to changes between different ghost writers, but generally Jessica found Todd boring and he thought of her as irresponsible and childish. ''Confidential'' retconned past events so that Jessica and Todd had been seeing each other secretly ever since college, where they became madly attracted to each other after Jessica agreed to pose as Elizabeth and go as Todd's date to a party. They spend the book trying to reconcile with Elizabeth and regretful at what they've done to her, yet agreeing that their love is so strong it can't be denied. There's no real explanation as to what they see in each other (beyond Jessica thinking while drunk that Todd is better than her many failed past relationships), nor why their bond is supposed to be so strong. By the follow-up series ''The Sweet Life'' they are having problems in their marriage and their two-year-old son is torn between them, yet we're again told their love is strong enough to make it through the odds.
** Also in ''Sweet Valley Confidential'', Steven Wakefield comes out as gay and leaves his wife for Aaron Dallas. Like Jessica and Todd, they fight against the odds for their love and we're told they are soul mates, yet there's no explanation of the relationship, with the book suggesting that they're attracted to each other just because they are the two designated queer characters (going so far as to claim Aaron "became" gay by moving to San Francisco).
* Creator/TedDekker does this in all of his later books, and some of his earlier ones. ''Immanuel's Veins'' was a vampire romance novel, which was depressing when you compare it to some of his original works like the Circle series and ''Literature/{{Thr3e}}''. ''Obsessed'' was from the very start a man ferociously in love with some girl he had never met or seen. Even in some of his books that give relationships more time to build up, it's less talking about why his main character loves a woman, and more about how intense his love is.
* ''Literature/{{Twilight}}'' has this both InUniverse with the concept of "imprinting", which means this can be done to werewolves as soon as the plot demands (arguably, all the examples in book 3 were only to prepare the reader for the last one), and out-of-universe with Bella and Edward's relationship. Edward acts surly and moody toward Bella for the first half of the book, and yet Bella decides that she's "unconditionally and irrevocably in love with [Edward]" ''right after she realizes that he's a vampire who thirsts after her blood'', and is completely devoted to him from that point on, even in the face of Edward's own warnings about how he could ''kill'' her. Just how devoted is she? She's willing to give up her human life without any second thoughts to be with him forever after what can't be any more than a month of knowing him, and instantly leaps back into his arms after he renders her ''practically comatose'' by leaving her without explanation. ''And'' her interactions with Edward after the vampire "reveal" consist almost entirely of them repeatedly professing their love to one another and her even more repeatedly being "dazzled" by Edward's glorious beauty. To put it a little more into focus Bella's other love interest was made to be more of a boorish jerk in the third book when fans read the second book and a lot of them hoped Bella ended up with him instead, because the two of them had much better chemistry than Bella and Edward, the guy the author wanted her to be in a pairing with.
* Likewise, in the ''The Short Second Life Of Bree Tanner'', with Bree and Diego and, later, Freddie. Bree and Diego interact for one night, she spends most of it afraid that he's going to kill her, and by morning they seemingly are madly in love with each other. The same goes for Freddie. Since it's from Bree's point of view and the "relationships" between her and the guys are so muted, it's possible that we're supposed to see it as her mistaking simple friendship for love (which would fit with her background of being abused and neglected), except that nothing ever indicates this and she acts almost exactly the same way Bella does, including [[spoiler:being perfectly alright to die when she finds out he's gone, because life without him isn't worth living]].
* The ''Literature/ThursdayNext'' series does this intentionally: Thursday and Landen get a small subplot of how they get together in the first book but were already basically in love before the series starts without much ado. Jasper Fforde admitted to doing this to get all the romantic stuff out of the way and be able to concentrate on the real story.
* ''Literature/WarriorCats''
** Half Moon [[spoiler:or Stoneteller]] and Jayfeather[[spoiler:/Jay's Wing]]. They've only met twice, once in ''Long Shadows'' and again in ''Sign of the Moon'', and bam, Jayfeather has feelings for her. It's a bit of a jarring change, especially since it implies a bit of hypocrisy because he was angry at his mother [[spoiler:Leafpool, for falling in love as a medicine cat]]. Watch the BrokenBase fandom get up in arms over whether they're a super cute pairing that brought tears to their eyes or whether their love is too cheesy and Half Moon is a SatelliteLoveInterest, and cue the Jayfeather/Cinderheart, Jayfeather/Willowshine, Jayfeather/Briarlight, [[CargoShip Jayfeather/Stick]], Jayfeather/Anyone but Half Moon shippers [[DieForOurShip bashing Half-Moon six ways to Sunday]].
** Bluestar and [[spoiler:Oakheart]] have similar problems. They hardly meet at all up until he is suddenly begging Bluestar (then Bluefur) to meet at Fourtrees. Up until this point, Bluestar ''hated'' [[spoiler:Oakheart]] for months (though this was clearly intended to be BelligerentSexualTension) and had only recently developed a crush on him. They then spend ''one night'' together, which ends with [[spoiler:Bluestar getting pregnant.]] And all this is later painted as a great tragic love story.
** It's a running problem with cross-Clan relationships in ''Warriors''. In addition to the above example, Crowfeather and [[spoiler:Leafpool]] really get this as well. They jump from acquaintances to in love before you could say 'mouse'. Next thing you know, they're running away together, and just like Bluestar and [[spoiler:Oakheart]] they [[spoiler:get pregnant from a one-night stand.]]
* ''Literature/TheWheelOfTime'' took this trope and beat it to death, with a ''canonical'' expression of "weird stuff happens because the plot says so". Probably the most notable example of this trope is Rand's relationship with Elayne. The characters themselves feel pretty manipulated, but hey, prophecy can do that to you! Lan and Nynaeve is also pretty bad. The period during which they fall in love in book one is completely off-page, yet we're supposed to buy that it's strong enough that in the very next book, Nynaeve is [[{{Wangst}} shoving thorns through her palms at the thought of not being with him.]]
* The vast majority of characters in ''Literature/{{Xanth}}'', particularly in the latter books, are paired up within days--if not hours--of meeting each other. This manifests in-universe as the land itself being a GeniusLoci ShipperOnDeck: There's natural ''love springs'' that can send any zoological CrackPairing off to start making some rather interesting hybrids.
* ''Literature/The39Clues''--most of the canon pairings introduced from the second series onward involve LoveAtFirstSight (which wouldn't be so problematic if it didn't occur with every single pairing), and readers are supposed to immediately accept that these two characters who just met are madly in love. For example: [[spoiler: Ian Kabra and Cara Pierce]]. Even the AnguishedDeclarationOfLove between Amy and [[spoiler: Jake]] in ''Day of Doom'', after the two have had several books' worth of UnresolvedSexualTension, seems awkward and forced because the scene is executed poorly, with both characters coming across as overly sappy and out of character, especially since Amy [[spoiler: was still in a relationship with Evan Tolliver at the time and is not the type of person who would cheat]].
* The early ''Literature/NightWatch'' novels have this with Anton and Svetlana. It seems the only reason they're together is because Gesar says so. In fact, Svetlana is frustrated that Anton seems to be taking the fact that they're going to end up together for granted, culminating in her having a threesome with two of his colleagues during a weekend getaway with Anton in the next room. When he finds out that truth, his calm acceptance and brushing off of this infuriates her, further pointing out how he doesn't care about it because their future together is set. It's pointed out, however, that Anton's big problem is Svetlana's power level, which is far above his. Historically, such relationships haven't lasted among Others. Their relationship is temporarily salvaged, when Svetlana is drained by the Mirror, making them more or less even. In later novels, they're HappilyMarried and raising a daughter, especially after [[spoiler:Anton is boosted to Svetlana's power level]]. It's not clear what will happen after ''Sixth Watch'', when [[spoiler:Anton is BroughtDownToNormal permanently, meaning Svetlana will outlive him by centuries]].
* The relationship between Eowyn and Faramir in ''Literature/TheLordOfTheRings'' can seem like this, or at the very least, wedged-in. The truth is that Tolkien initially intended Eowyn and ''Aragorn'' to be together -- then believed they wouldn't be a good match as Aragorn was "too old and lordly and grim", so he backtracked and created Arwen, later joining Eowyn to Faramir. Tolkien's notes show this was plainly an afterthought.
* Something of an in-universe example in the ''Literature/FirebirdTrilogy''. Near the start of the story, Brenden Caldwell needs to perform a deep-access mental interrogation on Firebird Angelo. Since Firebird and Brenden are heavily connatural, such a deep mental connection causes them to both fall in love almost instantly, and they get married after only a handful more meetings. This looks ''very'' bizarre to outsiders, and even the telepathic Sentinels find it a bit odd (Sentinels marry quickly, but usually there's ''some'' build-up before they attempt a connaturality probe to see if they're suited for each other).
* Jon-Tom and Talea's relationship is handled this way in the ''Literature/{{Spellsinger}}'' novels. They meet in the first novel and go on an adventure together. Then they spend two novels without seeing each other while Jon-Tom moons over her. They finally meet up again in the fifth novel, approximately two or three years later. Talea admits that she's got feelings for Jon-Tom. In the time-skip between the fifth and sixth novels, they get married.

[[folder:Live Action TV]]
* ''Series/AllMyChildren'''s: Edmund and Maria. They begin dating in the wake of Edmund and Brooke's breakup and her subsequent marriage to Tad. While not unhappy with Maria, he still spends the entirety of their relationship pining away for Brooke, proposing to Maria only after Brooke has rejected him once and for all, trying to reunite with Brooke twice during his engagement to Maria, even telling Brooke at one point, "What I feel for her doesn't come within a country mile of what I feel for you", and even ditching his rehearsal dinner to be at Brooke's side during an operation. Literally out of nowhere, Edmund one day declares ''Maria'' to be the love of his life. While it might actually be one of the better examples of this trope—-they go on to have a genuinely blissful marriage until she's "killed" in a plane crash—it's still a glaring {{Retcon}}.
* ''Series/{{Battlestar Galactica|2003}}'':
** Apollo was in a forced and loveless marriage with Dualla. Website/{{T|elevisionWithoutPity}}WoP even coined a term for it: "The Love That All of a Sudden". There were scenes in several previous episodes that showed them growing closer to each other, all of which ended up being cut. Eventually the writers just said "screw it" and threw them together without any buildup. It also didn't help that they hooked up in the very next episode after Dualla's boyfriend Billy was tragically killed, with the writing not being as clear as it could have been that at least a couple of months had passed, making it look like they practically started making out over Billy's corpse.
** Chief and Cally. After a TimeSkip of one year they go from being friends and co-workers to married. The last time they were seen interacting was when Chief smashed Cally's face in after she woke him from a suicidal dream. This one at least had some hints prior to the time skip, as Cally was clearly seen crushing on the Chief on several occassions prior to the beatdown.
* ''Series/{{Bramwell}}'' does this twice.
** At the end of the second-to-last season, the title character accepts a proposal from her colleague Dr. Marsham, even though ''he himself'' states that he knows she doesn't love him the way he loves her and is only agreeing to marriage to save herself from spinsterhood. Problem is, he made this declaration of love once, several years ago, but immediately took it back and apologized, given that he was married, and never brought it up again, indicating that he'd gotten over his feelings.
** Then in the final season, she meets an army major and within a few weeks is cheating on Dr. Marsham with him, engaging in WallBangHer sex while at a party. She conceives from this, and the series concludes with them getting married. We're led to believe that this man is the love of Eleanor's life, despite the fact that she barely knows him and probably wouldn't have considered marriage if she weren't pregnant.
* ''Series/BrooklynNineNine'':
** Rosa's relationship with Holt's nephew Marcus in the second season often comes off like this. The relationship is supposedly one of the most significant that Rosa's ever had and she is apparently deeply attached to him. However, the fact that Marcus was hardly ever around, when he was he didn't really seem that interesting or appear to have many distinguishing characteristics, and the fact that Rosa, by nature TheStoic, didn't really show a lot of emotion in general, made it easy for viewers to wonder exactly what the big deal was supposed to be.
** This gets even weirder in Season 3, when Rosa very suddenly falls in love with Adrian Pimento a mere few episodes after the character is introduced. He's a weird and creepy enough character to make it believable that Rosa would have a thing for him, but their sudden leap from "just met" to "we're getting married in a week" is jarring, to say the least. It's possibly lampshaded by the writers in the scene where they get engaged, right in the middle of making an arrest, with no buildup, fanfare, or anything the audience would consider even remotely romantic. Their whirlwind romance ends up being the catalyst for the season-ending cliffhanger, as the Nine-Nine ends up banding together to protect Adrian from a mob hit. One can easily get the impression that the relationship was introduced to keep the audience from wondering why the rest of the precinct would come together so easily in support of an officer they barely know, who is a bit of a loose cannon that most of the rest of them feel incredibly uncomfortable around.
* ''Series/BuffyTheVampireSlayer'':
** Buffy and Riley had no hope right from the start. Granted, the writers ''tried'', but they tried so badly to make Riley [[ReplacementScrappy "not Angel"]] that they forgot to give him any interesting character traits of his own - or any that would make him even the slightest bit compatible with Buffy.
** For Willow/Kennedy in season 7, the writers didn't even try at all. Literally the only reason they start a relationship is because Kennedy is also a lesbian, and Kennedy seems determined to not have any likable traits whatsoever. It's a huge letdown after Willow and Tara's relationship, which out of the whole show had the most build-up and most development.
* Kevin and Molly's affair from ''Series/CoronationStreet'' really seemed like just an excuse to have an affair storyline because they hadn't had one in a while. The attraction suddenly developed when the two of them started going running and after about three weeks they were ready to hop in the sack. Bear in mind Kevin was HappilyMarried with two kids and Molly was also HappilyMarried, and a key part of her character was how much she valued trust in a relationship. Also there was about a 15-year age gap between them and it apparently developed into true love so much that when Kevin called off the affair because his wife had cancer, Molly couldn't understand why...
* ''Series/{{Degrassi}}'' abuses this to an infuriating degree. Probably the worst example is in the movie ''Degrassi Takes Manhattan''. Fan-favorite couple, Jane and Spinner, end up splitting up. And who does Spinner turn to? Not any of his many exes (all of whom he's turned to comfort before) or even some random one-shot hook up character. The [[WhatDidIDoLastNight morning after drunken festivities]] with his pals, he awakes to [[spoiler:find himself ''[[AccidentalMarriage married]]'' to Emma. Yes, ''that'' [[CreatorsPet Emma]];]] the one who spoke to him a grand total of ''one time'' before the movie, and that one time was her telling him off at the very, very beginning of the show when [[spoiler: Spinner bullied Innocent!Manny]]. Instead of getting the marriage annulled, they say 'what the hell?' and see if the romance roulette will actually work.
* ''Series/{{Dexter}}'':
** The fourth season's opening episode features a brand-new relationship between Lt. [=LaGuerta=] and Sgt. Batista, which apparently developed entirely in the gap between seasons, despite no previous chemistry other than a standard-for-the-precinct friendship. Batista was even involved in an entirely different (and more developed) relationship as of the last episode of the previous season which vanished without a trace sometime in the meanwhile. [[RuleOfDrama Overstated drama]] immediately ensues over everything from policies against office romances necessitating secrecy to overblown arguments over shared bank accounts and Batista fighting in bars to defend [=LaGuerta=]'s honor. Meanwhile, neither the show's primary nor secondary storyline is even remotely affected by any of this, and the rest of the cast largely ignores it. It just takes a lot of screen time in Seasons 4 and 5. Then in Season 6 they are suddenly ''divorced''.
** Season 7 had Dexter and Hannah [=McKay=]. They have little chemistry and hook up ''very'' suddenly, and pretty much the only thing they have in common is they're both serial killers. It's obviously meant to set up an emotional moment when Deb is forced to arrest Hannah; after all, she was "the only person who'd ever accepted Dexter"...except that the writers apparently forgot about Lila West and Lumen Pierce, both of whom had been perfectly willing to accept Dexter's killing, the latter even helping him out in the exact same way that Hannah did. The whole thing just felt rather forced. It happened again in Season 8, with Hannah showing up again out of nowhere, and she and Dexter bacl together within two episodes. Even Dr. Vogel, an expert on psychology and human behavior, couldn't stop gushing about how utterly perfect they were for each other.
* ''Series/DoctorWho'':
** "The Invasion of Time": Companion Leela decides to stay on Gallifrey and marry the guard Andred, even though there's been nothing romantic between them. While the actors tried to suggest some attraction within the story, the script didn't give them much to work with. It's basically, Doctor: "Come on, Leela, let's go." Leela: "No, I'm going to stay here and marry Andred." Doctor: "Okay, bye." This happened because the actress told the producer she was leaving at the end of the season, and he kept trying to change her mind. The Big Finish audio drama series ''Gallifrey'' ends up subverting this relationship in a fairly satisfying way.
** The posthumous pairing of Peri with King Yrcanos at the end of "The Trial of a Time Lord". Apparently, Colin Baker was distressed by Peri's death at the end of the "Mindwarp" portion of the StoryArc and mentioned this to producer John Nathan-Turner. JNT, in his usual subtle way, fixed the problem by giving the Inquisitor a quick line stating that Peri is living happily with Yrcanos as a warrior queen, despite how nothing in the story, apart from the brief clip of his putting his hand on her shoulder that is shown ''after'' that line, supports that romance, and doing a {{Retcon}} of it makes a hash of the entire end of the story.
** Susan, Vicki, and Jo are three other female companions who were written out of the show by perfunctorily marrying them off, though while the relationships had [[FourthDateMarriage very rapid development]] (one serial apiece) they weren't as completely out-of-nowhere as the two above. Still, with regards to Vicki as soon as she's gratuitously renamed "[[Theatre/TroilusAndCressida Cressida]]" by Agamemnon simply because he doesn't like her real name, it should be quite clear to the viewers where this is going.
** Martha Jones and Mickey Smith, two characters who before "Journey's End" had never even met, and had only been onscreen together in the scene where ''everybody from the new series ever'' flies the TARDIS, are shown in their "happy ending" vignette in "The End of Time" as a married couple, freelancers, and fighting a Sontaran. This is despite the fact that Martha had been shown to be engaged in a previous appearance (though her fiancé never showed up). It ends up looking like a bad case of PairTheSpares, and an even worse case of the TokenMinorityCouple.
** In their early days, River and Eleven fell into this trope for some fans due to the main gimmick of their relationship being that [[HaveWeMetYet they meet in the wrong order and therefore one tends to gain affection as the other loses it]]. Post-"The Wedding of River Song" they were on the same wavelength, alleviating this aspect of their relationship.
** Clara Oswald and Danny Pink's romance in Series 8 was criticized for being poorly written and too rapidly developed -- in his second appearance, "Listen", they go on a disastrous first date, yet they're firmly a couple by the end anyway. ''Then'' a LoveTriangle situation with Twelve is brought into the picture two episodes after that, with only half a season to go! Then again, it all ends when [[spoiler: Danny is killed]] in the SeasonFinale, with a coda in the ChristmasEpisode afterward. A fan theory is that this storyline was written to maintain an overt romantic plot in the show out of fear that just carrying Clara's relationship with the Eleventh Doctor over to the Twelfth with little change would have alienated viewers due to Twelve being played by a much older actor. This backfired, partially because Clara and Twelve's initially rocky relationship smoothed out and became a much more convincing, if subtler, romance.
** The Twelfth Doctor and River Song are sometimes criticized as undergoing this due to the "wrong time in the narrative" issue. In the 2015 ChristmasEpisode "The Husbands of River Song", it's revealed that River Song still had doubts that the Doctor truly loved her, not thinking it was in his nature; the story also did a {{Retcon}} of the Eleven-era short "Last Night" ([[spoiler: Eleven didn't take her to the Singing Towers after all]]). Twelve doesn't hide his attraction to her, and the ending of this story reveals [[spoiler: Twelve was with River at the Singing Towers, and the "night" they spent there lasted twenty-four years, effectively making him her "true" husband]]. The problem with this is that "Husbands" aired just ''three weeks'' after the tragic three-part Series 9 finale that saw his long and well-established relationship with Clara Oswald come to a sad end, and many fans felt it was too soon for him to be so attracted to another even with his previous selves' established history with River. In Twelve's defense, however, 1) his relationship with Clara was codependently toxic by the end and they were forced to realize it was doing everyone more harm than good (after all, he [[spoiler: risked the space-time continuum to undo her death]]), and 2) he [[spoiler: was effectively mind-wiped of his love for her]], so he wasn't brooding (much) over its dissolution by the time he met River again. Also, the ExpandedUniverse went on to establish he traveled on his own or with CanonForeigner companions for quite a while between "Hell Bent" and "Husbands", again giving him time to move beyond Clara.
* In ''Series/{{Ellen}}'', Paige and Spence, who at first hated each other, become passionate lovers after the course of season three.
* ''Series/FamilyMatters'' had Steve being in love with Laura from the beginning, despite how she had never given him any hopes that he would win her heart and was even mean to him during the first couple of seasons. And it was clear that she preferred the JerkJock type, which was the polar opposite of Steve's nerdy personality. And for a couple of seasons, when Steve had a serious relationship with Myra and he had become friends with Laura, Steve's crush on Laura was almost forgotten about. But then came the 9th and last season, when it seems like the writers suddenly decided that Steve and Laura just ''had to'' end up together, despite how they both were in serious relationships with other people...
* ''Series/{{Friends}}'':
** Chandler and Monica are a perfect example of this and TropesAreNotBad. No matters what the shippers think, in the first four seasons they were not attracted to each other: they were close friends but just as close as ''anyone else in the group.'' They have a few sweet moments ("The One With The Birth", "The One With The Flashback", "The One With The Jellyfish") just like pretty much every girl/guy pairing on the show, but it was always platonic. Also, for most of season 4 they rarely have a one-to-one interaction... until the last episode when they spend a night together in London: this was the start of the Chandler/Monica era. Luckily, it was very well written and it becomes immediately popular with fans. We see their relationship gradually evolving from sexual to romantic and Chandler gradually overcoming his fear of commitment and become HappilyMarried. It helps they have great chemistry.
** The infamous [[NoSparks Joey and Rachel]] romance. Season 8 has Joey developing feelings for Rachel, which was kind of unbelievable but, thanks to Matt's acting skill, pretty emotive. Rachel gently turned him down and the incident was barely mentioned again until Season 9 when Joey got a new girlfriend and all of a sudden, Rachel gets a crush on Joey! They hooked up in the finale, stayed together for maybe 3 episodes...and then broke up because, they uh, couldn't do it 'sexually'. What? Made worse as Rachel had ''exactly'' the same problem with Ross in S2 but made it through. However, the writers always planned to get Ross and Rachel together in the end, making the whole thing a ShaggyDogStory. About the only thing it achieved was making Rachel look unnecessarily shallow and fickle.
* ''Series/GameOfThrones'':
** Robb Stark and Talisa Maegyr in the second and third season. The show's FourLinesAllWaiting structure meant there wasn't nearly enough time to develop a proper romance between them, yet we're still supposed to accept that, after just a few conversations, Robb is so in love with Talisa that he's willing to risk his entire war campaign falling apart to marry her. It doesn't help that, in [[Literature/ASongOfIceAndFire the source material]], Robb marrying Jeyne Westerling ([[ReplacementLoveInterest whom Talisa replaced in the show]]) had less to do with love and more to do with preserving her honor after he'd taken her virginity, and the whole relationship was portrayed as not nearly worth the problems it caused.
** Daenerys and Jon Snow are even worse. The showrunners, writers, the actors, and other characters insist from the moment these two meet that Dany and Jon are obviously already crushing on one another. The actual on-screen chemistry however is extremely lacking and even antagonistic. Not only that but both have already been involved in serious relationships (Dany for love and politics and more than once) and being royalty in a time of crisis, for the two of them to suddenly develop spontaneous crushes on one another comes across as painfully immature. This is a particularly irritating example because it's now been confirmed that, as many book readers surmised, Daenerys and Jon and their eventual relationship are one of the things that the ''Song of Ice and Fire'' title refers to and their coming together to defeat the white walkers is the ultimate point of the series. So their relationship is one thing which absolutely should ''not'' have been handled ham-fistedly.
* ''Series/{{Glee}}'':
** Tina and Mike Chang, who never interacted in S1 (Mike only spoke one line), and were basically put together for Asian jokes. Since then they have at least gotten some relationship development, although much of it was offscreen.
** Mercedes and Sam. Enforced as [[RealLifeWritesThePlot Sam's actor temporarily left the series due to contract disputes]] right after Mercedes and Sam got together. When he returned, the writers treated their relationship like some tragic love story. Because it had next to no development, it was hard for most viewers to buy into that and get invested in the relationship.
** Brittany and Artie started off this way, and earned the show lots of InternetBackdraft from angry [=Brittany/Santana=] fans. It became clearer over time that Artie was intended as a RomanticFalseLead, and the whole relationship was designed to [[GreenEyedEpiphany force Santana to realize her feelings for Brittany]].
** One that carries some UnfortunateImplications: Sam was originally created to be a love interest for Kurt, but was changed to be straight when Ryan Murphy apparently noticed chemistry between him and Quinn so strong that it just couldn't be denied (and which many fans have been quick to point out doesn't seem to come across onscreen). To his credit, he did also create another character as a love interest for Kurt afterwards.
** While the show had teased Kurt and Blaine for a while after Blaine's introduction "Never Been Kissed," after the mid-season break the show seemed to be heading in the exact opposite direction, trying to convince the viewers that the two were BetterAsFriends by having Blaine fall for other people and turn down Kurt's advances while excelling in a mentor-like role. However, in "Original Song," Kurt's rendition of "Blackbird" causes Blaine to suddenly reverse his feelings and he and Kurt are sucking face just a few minutes later.
** More broadly, the show has been criticized for turning to these repeatedly to create tension between its A couples of Finn/Rachel, Kurt/Blaine and, to a lesser extent, Brittany/Santana. They'd split up, often by cheating on or to hook up with a RomanticFalseLead out of the blue, and spend half a season needing to re-realize their true feelings for each other.
* ''Series/HannahMontana'': Lilly and Oliver have been [[VictoriousChildhoodFriend friends]] since [[ChildhoodFriendRomance kindergarten]]. They've seen the best and worst of each other, the best and worst of times, and have been there for each other through all of it. Let's not forget that they have [[BirdsOfAFeather numerous common interests.]] Do the writers use any of these perfectly legitimate story elements as a basis for their RelationshipUpgrade? Please, this is the Disney Channel! Instead, we get some contrived story about how her head fit into his neck and how she smelled like apples. And they go from being good friends to [[SickeninglySweethearts all PDA all the time.]] Even Miley gets sick of the RomanticPlotTumor, and its especially odd since the writers seemed to be slowly setting Oliver up with Miley in prior episodes, including one in the same season.
* ''Series/{{Heroes}}'' had Matt Parkman and Daphne in Volume 3, because Matt saw a future vision of himself married to her, and started going after her BecauseDestinySaysSo. She even asked what they had in common. Despite this, people prefer Daphne to Janice, Matt's wife/exwife/wife. Them getting back together is kind of an example because she reveals her baby is his and despite her cheating on him with his best friend, he immediately forgives her.
* Popular ''Series/HomeAndAway'' pairing Aden and Belle was considered random by a number of fans. Having never interacted prior to the 2008 season, they started working together and established a relationship based purely on insults, which half the audience interpreted as "secretly wanting to rip each other's clothes off" and the other half interpreted as "genuinely not liking each other" until one episode when she insults him, he looks like he's going to cry and her [[AuthorAvatar best friend]] declares that he likes her. A few weeks later, when the closest they've come to a meaningful conversation is her sitting silent while he chats to his surrogate father, he drunkenly climbs through her bedroom window and gets into bed with her, which apparently means they're now a couple.
* Foreman and Thirteen on ''Series/{{House}}'', who went from "awkward conversations in the locker room" to "awkward kiss in a conference room" to "willing to commit career suicide for this person" in the span of about two weeks. Which is lampshaded by Thirteen herself at one point.
* ''Series/HouseOfAnubis'':
** Fabian and Mara. For most of the show, they had only about four lines of dialogue together, and then suddenly started showing signs of romance in the last minute of the season 3 finale. In ''[[TheMovie The Touchstone Of Ra]]'', they suddenly ended up kissing. While it's very true that they are very much alike, it's still very jarring, and has only helped fuel Mara's [[TheScrappy Scrappy status]].
** Alfie and Willow fit this to a lesser extent. On one episode, out of nowhere, Alfie decided he had feelings for Willow. However, this does not make the pairing bad, as many fans have become attached to this pairing for their relatively drama-free attitude (which is rare for this show), their similarities, and their funny scenes together.
** Alfie has this with Piper, which makes sense because Piper was only on the show for three episodes. It's downplayed, in that he had originally believed she was Patricia, her twin, who he knew for years, and they had a few scenes together that showed them growing closer, which makes their short lived relationship more believable.
* ''Series/HowIMetYourMother'' had this with [[spoiler: Ted and Robin getting together in the final episode. While they were the OfficialCouple for most of the show, the previous season had made a whole plotline out of Ted letting go of Robin and accepting that they just weren't meant to be together, opening up room for him to meet The Mother. Who was then killed off, and Robin and Barney got divorced, then Ted and Robin got together, despite it being established that Robin at that point had not spoken to the group for years due to just not fitting in anymore, presumably including Ted]].
* ''Series/ICarly'' does this with Sam and Freddie for their brief hook up in season 4. [[ShipToShipCombat Regardless of whether]] you are a [[PortmanteauCoupleName Seddie or Creddie]] shipper, and while Sam and Freddie's fighting could be ([[ShippingGoggles and definitely was by their shippers]]) interpreted as BelligerentSexualTension, the actual hook up comes off like this. Rather than a convincing SlapSlapKiss, as most BST couples get, all the audience gets is Freddie using his very strange mood app ([[DeusExMachina which receives no explanation]]) to read Sam's mood, which reveals it as "in love", which Freddie thinks applies to Brad, and when he confronts Sam about it, she suddenly kisses him.
* ''Series/{{Lost}}'':
** Sayid with Shannon, who made him forget the love of his life (which almost borders this trope, since they were childhood friends, but reconnected during the month she was a prisoner of the army he was serving). [[CartwrightCurse Doesn't last long]], but in the series finale, he [[spoiler:hooks up with Shannon again in the afterlife]], establishing her instead of Nadia as the love of his life and his soulmate. What.
** Sawyer and [[ActionGirl Juliet]] hooked up in season five although they barely even spoke to each other for the previous two seasons. However, it worked: the show [[spoiler:skips ahead in time]] and uses their relationship as a surprisingly effective [[TheReveal reveal]].
* ''Series/{{Merlin|2008}}'':
** Arthur/Guinevere, one that has led to something of a BrokenBase among the fandom. Neither Arthur nor Guinevere interacted very much in season one, although the scenes that they ''did'' share had a strong emotional punch to them (Arthur comforts Gwen after her father's death, Gwen tends Arthur on his sick-bed, etc), but come the second episode of season two, Arthur stays at Gwen's house for a short period of time and impulsively kisses her when the time comes to leave. From this point, there are several rather overwrought declarations ("I care about her more than anyone!" and "Anyone who spends five minutes with you can see how you feel about each other!") that don't feel particularly earned, as well as violins, slow-motion, and dramatic back-lighting whenever they're together (and at least one TrueLovesKiss). Things improved a bit in the third season when Arthur/Gwen were given more of a chance to flirt and ''have actual conversations''.
** Merlin/Freya, a RescueRomance that begins with Merlin saving Freya from a BountyHunter, suddenly having the young warlock willing to give up his entire life in Camelot to run away with a girl he’s had exactly three short conversations with. The only reason he doesn’t go through with it is because [[TemporaryLoveInterest Freya didn’t survive the episode]].
* ''Series/TheNanny'': Despite a few moments of BelligerentSexualTension (like the kiss in the first season 3 episode), Niles and C.C. ''hate'' each other and Niles loves to insult and torment C.C. for most of the show...until the last season when Niles suddenly reveals that he's actually ''in love with her'' and decides he wants to marry her. Then we only know that C.C. turns him down several times and after an argument Niles gives her a TheReasonYouSuckSpeech...[[spoiler:however at the end of the episode they are discovered in bed together without any explanation. After that, they almost never interact on-screen but it's implied they are having a secret relationship. In the last episode they get married in Fran's DELIVERY ROOM and in the same scene C.C. even learns that she is pregnant with Niles' baby.]]
* ''Series/{{NCIS}}''. Following her divorce after her heretofore loving husband was turned into a [[DerailingLoveInterests cheating SOB]], within the course of THREE episodes scattered over a few months, Ellie Bishop was revealed to be in a new relationship, to have her new boyfriend killed off, and to have their love story depicted via flashbacks, capped off with the reveal that she would have accepted his proposal had he not died. Aside from the time frame making it unlikely that they could have been involved long enough to be considering marriage, their relationship is glaringly different from nearly all others the show has depicted, where considerable time was spent developing the character and the romance, and as such, his death fails to have any emotional impact.
* ''Series/OnceUponATime'': Season four saw [[spoiler: Belle]] [[AbsenceMakesTheHeartGoYonder hooking up with someone else]] not long after [[spoiler: she forced Mr. Gold to leave Storybrooke]]. This someone was [[spoiler: Will Scarlet]], someone who she scarcely interacted with before-hand.
** Even more strangely, the entire storyline for [[spoiler: Will Scarlet]] was dropped without much explanation, and the character was [[ChuckCunninghamSyndrome Brother Chucked]], leaving [[spoiler:Belle and Gold]] free to snap back to OfficialCouple status, and the mystery of what happened to [[spoiler:The Red Queen, who was last shown as Will's wife in the finale of ''Series/OnceUponATimeInWonderland'']] completely unresolved, despite a scene earlier in Season 4 hinting that he was still looking for her.
* In ''Series/TheOriginals'' Hayley and Elijah interacted ''once'' before he's [[spoiler:daggered]] and she's reading his journals and missing him badly, and Elijah has barely been back for one scene before he's chasing after her like a lost puppy.
* Some seasons of ''Franchise/PowerRangers'' have this in effect.
** In ''Zeo'', a future seen in a Christmas episode had Tommy eventually married to Catherine, when they'd never really shown a romantic attraction before and Tommy's only love interest in the show up until that point had been Kimberly during ''Mighty Morphin'', who'd moved out of Angel Grove by the time that episode had come around.
** ''Samurai''/''Super Samurai'' had a forced last-minute hook-up with Mike and Emily in the last episode, despite the fact that they'd never shown a romantic interest in each other prior. The only hint at this eventual hook-up was Scott in ''Clash of the Red Rangers'' suggesting Emily looked at him like she had a crush on him, despite no direction, camera shots, or dialogue having suggested it not only the entire season prior, but even in that special itself.
*** There's also a secondary relationship that Daiyu and Decker had, since it was revealed that they'd loved each other hundreds of years prior to the series. The problem? Decker doesn't remember his life before becoming half Nighlok due to amnesia and Daiyu ''doesn't even remotely try to remind him'' about their past together. It's not helped that this development wasn't even remotely in ''Shinkenger,'' the series' source material, so it didn't have that kind of relationship between their counterparts. The seasons relied so heavily on retelling the ''Shinkenger'' storyline that even the changes they ''did'' make either didn't add up to much, or were to the series' detriment.
** ''Megaforce''/''Super Megaforce'' has it arguably worse. Though it's shown Jake has a crush on Gia in the first season, it's an unrequited crush (also trying to be helped by the fact that their counterparts in ''Goseiger'' were ''brother and sister'' and, thus, they belonged to the same clan, which derived their ground motifs and had their mechs work in tandem a lot). After that, Gia apparently shows reciprocation of his feelings, but ''doesn't even bother to tell him''. By the time ''Super'' comes around, the show was ''way'' too focused on cannibalizing the ''Gokaiger'' footage and plots it was adapting to try to make on seamless continuity between it and the previous season to focus on ''anything'' in that direction, not helped by the fact that none of ''Gokaiger's'' characters had romantic feelings for each other. By the time the finale came around, there was ''nothing'' suggesting that they were going to get together, so when Gia kisses Jake on the cheek, it comes right the hell out of nowhere, which is arguably worse than ''Samurai's'' situation, since it was given a bit of development, dropped, then picked back up at the ending of the season, where as ''Samurai'' just had it barely established, then had it dropped into the last episode.
** Tellingly, when Judd Lynn took over as showrunner from Jonathan Tzachor for ''Dino Charge'', he instilled a good amount of establishment of Tyler and Shelby's eventual hook-up, not only righting the wrongs of the previous four seasons before it, but also its ''Sentai'' source material, ''Kyoryuger'', as described below in the ''Super Sentai'' section.
* ''Series/RobinHood'':
** Much falls instantly in love with [[TheScrappy Kate]], because...well, the writers never got that far. She treats him like crap, but he never stops mooning over her and eventually goes so far as to (temporarily) abandon the outlaws when he realizes that she has a crush on Robin.
** And what about Robin going from “my-true-love-[[DiedInYourArmsTonight died-in-my-arms]]-and-I-will-never-love-again” to “Wow, okay, Isabella’s hot, I’ll just go…romp in the bushes with her” thing in season 3? Maybe there was some EvilIsSexy sexual tension, but romance? This makes Robin look like an unfaithful jerk after the huge balloon of suicidal angst that was the season opener. There was no explanation as to why Robin suddenly abandoned his angst over his true love for this woman who, incidentally, is the sister of his archnemesis and possibly trying to kill him.
* A straight example in the final season of ''Series/SabrinaTheTeenageWitch'' that ultimately evolves into a Deconstruction. Sabrina falls for Aaron in his debut episode so much that she uses magic to find out what his flaws are. They hook up at the end of the episode and for the rest of the season simply act as a couple that's been together for years, rather than developing slowly. It's never explained why Sabrina literally makes room for him in her heart. However cracks start to appear as Sabrina initially thinks his proposal is a trick caused by the MonsterOfTheWeek and accepts reluctantly. The rest of her actions during their engagement come across as straight-up denial more than anything else. Finally when her wedding day comes, she gets cold feet and dithers between that and denial. [[spoiler: She and Aaron ultimately agree to call off the wedding.]] It's worth noting that this plot wasn't supposed to be an example of this trope. The showrunners originally wanted Sabrina to develop a serious relationship with Josh, a character who'd been on the show since Season Four; the two really ''had'' known each other for years, and their back-and-forth feelings for each other were a recurring subplot. The problem--Josh's actor didn't want to come back for the last season, forcing the producers to come up with a last-minute replacement.
* ''Series/TheSecretLifeOfTheAmericanTeenager'':
** Ben and Amy. They had an ok relationship for the first few episodes (if you ignore that a. Ben only originally asked her out because he was hoping to get some sexual experience before going after the ''real'' object of his affections, [[AllGuysWantCheerleaders Grace]] and b. Amy wasn't upfront either, since she didn't tell him she was pregnant). For the most part, they were believable as two earnest, awkward teens in their first relationship. Then Ben proposed to Amy after they'd been dating a few weeks, upon discovering she was pregnant with Ricky's baby. Now the audience was supposed to accept that Amy and Ben had a deep and true love to last their whole lives and they and the other characters [[ShowDontTell wouldn't shut up about how right they were for each other]].
** In season four, Ben got a new love interest named [[TomboyishName Dylan]] and this happened again. They were inseparable almost instantly, which included Dylan [[StalkerWithACrush showing up unexpectedly at Ben's house and school]] within the first week or so of their relationship.
* ''Series/{{Smallville}}'s'' one example that's almost-universally agreed upon is the Clana (Clark and Lana) ship, which was arguably kept on way past the point of its usefulness to the plot, interfered with other plotlines that fans wanted to see, and seemed to slow down Clark's growth.
* ''Series/StargateAtlantis'' does throw in a few moments that make it clear Keller and [=McKay=] are interested in each other, but they go from eating lunch together once (while he was in the infirmary) to him professing his love when he thinks he's going to die. A couple of episodes later, with no intermediate interaction, she says she loves him, too.
* In ''Series/StarTrekTheNextGeneration'' S7 Ep 11 "Parallels", Worf is sent multiverse-hopping, and he briefly winds up in a world where he and Troi are very HappilyMarried. While he had never considered this before, he decided to give it a try when he got back. This was the starting point of the writers developing a bizarre obsession with hooking them up despite the two never having any kind of romantic chemistry before, as well as Troi having a longstanding WillTheyOrWontThey with Riker. Creator/JonathanFrakes (Riker) and Marina Sirtis (Troi) apparently disliked the idea as well, and were quite happy to have their characters get married in [[Film/StarTrekNemesis their last film]]. Michael Dorn (Worf), on the other hand, refused to forget it, and, when given a line about how Riker and Troi's feelings for each other had never gone away, subtexted it like mad. Then Worf went aboard ''[[Series/StarTrekDeepSpaceNine DS9]]'', fell for Jadzia Dax, and acted as if he never even liked Deanna.
* ''Series/StarTrekDeepSpaceNine'':
** Nerys and Shakaar. Nerys even {{lampshade|Hanging}}s how sudden the beginning of the relationship was while talking to Odo, solely to make the audience feel sorry for Odo [[spoiler:because he just realized he's in love with Nerys]].
** Considering the above, it's funny how Worf and Jadzia have no romantic chemistry and no common interests besides the Dax symbiont's experiences with the Klingons.
** Jadzia and a one-off alien she meets in the season three episode, Meridian. The Defiant encounters a planet that shifts in and out of phase with this dimension, which has about 30 people living on it. Jadzia gets involved with the scientist living on the planet and ends up trying to take a leave of absence for 60 years to stay on the planet with him while it's shifted out of this dimension. Sisko looks like he's about to call her on this but then simply says he's happy for her instead. And then they find out that she can't actually survive the shift, she gets beamed back to the Defiant, and she never mentions or appears to think of him again.
* ''Series/StarTrekVoyager'' has Seven of Nine/Chakotay. After three and a half seasons of them having only a professional relationship and almost no interaction outside of business, Seven suddenly develops an unrequited attraction to Chakotay in the second half of the final season. In the finale the two have become romantically involved, with Chakotay having fallen completely head over heels for her in the span of... well, the theme song. Particularly sloppy in that between the episode in which Seven explores romantic interactions with a holodeck-Chakotay and the finale was an episode in which the two of them were trapped together on an alien world. The actors specifically asked if there would be any follow-up to the holodeck romance that they should incorporate into their performances and were given a firm "No" in response.
* ''Series/StepByStep'' had Dana Foster and Rich, who was her stepbrother's dimwitted friend. After spending two seasons barely able to stand being in the same room as each other, they suddenly started dating in season six... and still acted like they could barely stand to be in the same room as each other. In some episodes it really bordered on Informed Relationship.
* ''Franchise/SuperSentai'':
** At the end of ''Series/ZyudenSentaiKyoryuger'' after he returns from what was assumed by the rest of the cast to be a suicide mission, [[spoiler:Daigo (Kyoryu Red) gets together with Amy (Kyoryu Pink)]]. The problem with this is that both characters were depicted as {{Chaste Hero}}es who had no real relationship chemistry and no romantic interactions prior to their pairing up. The [[BrokenBase aftereffects]] of this little twist was foreseeable, not only because it came out of left field, but also because there were two other characters who actually did have romantic character development with [[spoiler:Daigo]]. Of course, considering many fans' [[CreatorsPet opinion on him]], this doesn't seem so surprising.
** In the same series, it's a running gag that Souji Rippukan [[ObliviousToLove never notices]] that Rin, his kendo team manager, has a huge crush on him (despite his friends' efforts to [[ShipperOnDeck set him up with her.]]) The sequel movie ''100 Years After'' retcons events so that Souji had begun dating Rin by the end of the TV series; but he still shows little interest in her and even completely forgets a date they had planned. However, it's revealed that they married shortly afterwards and were deeply in love until Rin died some time before Souji (who lives to be 116 years old.) There is no explanation for the sudden change in Souji's feelings.
** A third example from ''Kyoryuger'': in episode 41, Nossan is thrown with Candelira during an arranged marriage interview (where she was posing as a human to harvest emotion from lovelorn men) and they almost instantly fall in love, which is used to spur her into a HeelFaceTurn and leaving Deboss. This is made out to be very important to the plot and their characters, yet the only foreshadowing was a single line of dialogue in an early episode when Candelira said that she could fall for him if they weren't enemies.
** In ''Series/BakuryuuSentaiAbaranger'', Emiri and Yukito are suddenly in a relationship at the end of the last episode, with no prior romantic interaction between them. When they return for a team-up with [[Series/TokusouSentaiDekaranger the following year's series]] Emiri is completely devoted to Yukito and has begun to dress and talk differently to fit in with his upper-class background, becoming very unlike the carefree schoolgirl she was during the show. They reappear for a guest appearance in ''Series/KaizokuSentaiGokaiger'' where they are now married and Emiri is working as Yukito's secretary, but still completely in love with him and with no explanation as to how they got together in the first place or the change in Emiri's character.
** A similar example to the above is Sen and Umeko in ''Series/TokusouSentaiDekaranger''. They have a close friendship, but no romantic interaction until Episode 41 when Sen suddenly becomes jealous at Umeko getting engaged to another man. He proves that her boyfriend is an evil Alienizer, and Umeko suddenly realizes Sen has been the guy for her all along. Because it was close to the end of the show, there was no further time to focus on their relationship, so it doesn't really come up again until the crossover with ''Series/MahouSentaiMagiranger'' where other characters can't stop gushing about how perfect Sen and Umeko are for each other and how they are obviously in love. However, almost none of their relationship is ever shown to the audience to make this believable.
*** Sort-of amended by ''Dekaranger'''s "10 Years After" movie in which Sen and Umeko have been dating for a long time and have a few scenes together that make their relationship convincing. In the crossover with ''Series/UchuSentaiKyuranger'', they are shown to be engaged. The wedding happens in ''Space Squad: [[Film/SpaceSheriffGavanTheMovie Gavan]] vs Dekaranger'', but is interrupted twice (first by Gavan announcing that the world is in danger and second by Sen suffering nervousness-induced constipation).
* This happens InUniverse in ''Series/{{Supernatural}}'': The Angels (with the help of Cupid) arranged for Mary and John to meet and fall in love, even though they didn't get along at first, because they needed Sam and Dean to be born.
* ''Series/That70sShow'':
** The show played [[PlayedForLaughs this for laughs]] with Jackie and Hyde's hookup in Season 5. The two initially don't like each other at all, and it was only through their common friends that they're even in the same vicinity. They become better friends in Season 2 after he shows her how to deal with Laurie stealing Kelso from her. In Season 3, she becomes attracted to him and develops a clingy infatuation with him, which he's annoyed by, but he eventually caves and takes her out on a date. The two share a kiss, but Jackie says it didn't do anything for her and finally realizes Hyde isn't the guy for her. At this point they seem to have effectively [[ShipSinking been sunk]], and it's not brought up again until the Season 5 premier, when the others leave the room, and the two suddenly start making out and continue to do so. In the next episode, a flashback reveals they were watching TV and complaining about how bored they were, when they look at each other for a few seconds and spontaneously started making out. Yet, their relationship comes off as much more believable due because they give off a ton of chemistry together and by the fact that they initially spend a lot of time lampshading how strange it is.
** Sadly, the show also plays very straight in [[PostscriptSeason Season 8]], with not one, not two, but ''three'' pairings.
*** The first is Hyde and Sam. In the last episodes of the previous season, Jackie and Hyde had encountered issues with their relationship resulting in Hyde taking a trip to Las Vegas to clear his head. In the first episode of Season 8, he returns, and his and Jackie's great relationship is completely tossed out the window when Sam shows up completely out of the blue and reveals that Hyde [[WhatDidIDoLastNight got drunk]] and ''[[AccidentalMarriage married her]]''. Jackie spends a total of one episode afterward angsting over this before moving on, and while Sam isn't a bad character, she and Hyde have absolutely no chemistry together.
*** The second is caused by the first; Jackie and Fez. While Fez had a crush on Jackie since the start of the show, Jackie had never returned his feelings, not to mention Fez is a total horndog who was willing to nail AnythingThatMoves. She had even continuously ruled him out. She did kiss him once and go out on a date with him, but after each of those events she had straight up said it was impossible for anything to happen between them. Then after losing Hyde and getting over him, she makes up a list of qualities she needs in a man, and Fez miraculously turns out to fit it perfectly, and they end up a couple.
*** The third is Donna and [[CanonSue Randy]]. Eric and Kelso are PutOnABus for the final season, and both are given a SuspiciouslySimilarSubstitute in the form of [[ReplacementScrappy Randy]]. While Eric is in Africa for the final season, there's never any major indication that Eric and Donna's relationship is having issues. (The best the writers could come up with is Eric not talking to her on the phone.) Then, out of the blue again, Donna reveals that off-screen Eric broke up with her. After a WillTheyOrWontThey tease, she ends up dating Randy. Making this worse is that Donna was clearly attracted to Randy ''before'' Eric's break-up. This one gets an AuthorsSavingThrow twice over, however - most likely once it was known the show wouldn't be coming back for a ninth season. The two ultimately break-up rather quickly. Later, Eric [[BackForTheFinale returns in the finale]], where [[LampshadeHanging he admits he's not sure why they broke up in the first place]]. It's left up to viewers to decide if Eric and Donna get back together officially, which unsurprisingly, many prefer.
* ''Series/{{Torchwood}}'':
** Ianto accuses Captain Jack of being a monster for killing Ianto's Cyberman-girlfriend ([[ItMakesSenseInContext long story]]) but starts shagging him a few episodes later with no significant on-screen development. Mellows somewhat in Season 3 when the two have more frequent conversations and develop a more emotional relationship.
** Owen going bananas over Diane after knowing her for all of a week.
** The overly romantic light that Jack and his relationship with the real Jack Harkness was painted in, given they only know each other for a couple of hours.
** A curious case with Tosh and Tommy: Tommy has been in suspended animation since the First World War, but is let out for a day once a year to ensure that all is well. This means that he and Tosh have known each other for years, in a way, but in another way, they've known each other for about a week.
* ''Series/TrueBlood'':
** Eric and Sookie. When [[spoiler:she and Bill split]], it's been set up for the viewer to expect this, but doing it by [[spoiler:completely changing Eric's personality due to memory loss]]?
** Sookie and Bill. The two of them never talk about anything except about how much they are in love with one another or what's currently going on in the plot. In the books Sookie flat-out ADMITS that their love is shallow and that she got into a relationship with him because A.) she couldn't read his thoughts and B.) she's never actually been in a relationship before. She even breaks up with him far earlier than TV Sookie and barely angsts about it at all; the love is SUPPOSED to be shallow but the people making the TV show didn't know that. Later episodes also point out that, for most, drinking a vampire's blood makes you addicted, and if drunk "from the tap" you're also addicted to the ''vampire''. Given that Sookie only starts properly falling for Eric after drinking his blood (since vampire blood speeds human healing), it's speculated in-universe and out that that's the REAL reason he's on her mind.
* ''Series/TwinPeaks'' had two of these for the price of one; the concurrent romances between Dale Cooper and Annie Blackburn and Audrey Horne and John Justice Wheeler both involved main characters who were suddenly swept off their feet instantly by strangers visiting from out of town. The suddenness of both subplots is explained by [[RealLifeWritesThePlot Kyle MacLachlan's refusal to allow his character to date a teenager]]. Especially irking to fans who wanted to see the FanPreferredCouple of Cooper and Audrey together.
* ''Series/TheVampireDiaries'':
** Stefan and Elena in the first two episodes. Elena meets Stefan, a mysterious new student, they have two awkward conversations, and the next day they both already knew they were meant to be. They agree that "We met. We talked. It was epic" before sharing their first kiss and becoming a couple. However, despite the rushed beginning, the rest of the relationship was well written.
** Enzo and Bonnie. In season 5 and 6, they are frenemies at best and TheFriendsWhoNeverHang at worst. Most episodes in Season 6 focus on Bonnie's close [[PlatonicLifePartners platonic relationship]] with Damon, and her few interactions with Enzo are not very friendly if not outright antagonistic. However in season 7 they fall in love during the three year TimeSkip (we only see a flashback of their first date in one episode) and remain madly in love for the rest of the show to the point they can't live without each other.
* Veronica and Piz on ''Series/VeronicaMars'', which was a particularly JustForFun/{{egregious}} offense because the cancellation of the show left them together after. God bless WordOfGod; [[LastMinuteHookup "It was always Logan and Veronica."]]
* ''Series/{{Warehouse 13}}'''s six episode final season, after several seasons avoiding the cliche, lazily shoehorned in a romantic subplot for PlatonicLifePartners Myka and Pete.
* ''Series/{{Zoey 101}}'':
** Logan and Quinn are an example that proves this trope [[TropesAreTools does not make a couple bad]]. The two have little interaction for the first 3 and a half seasons, and the interaction they do have isn't friendly, and that does ''not'' mean BelligerentSexualTension. It just means unfriendly. Then midway through the final season, her boyfriend, Mark, leaves her for another girl. While she's sulking, Logan happens to be riding by and sees her looking sad and comes to talk to her. While she initially resists his attempts to cheer her up and even asks why he's doing so, he showers her with compliments and then puts [[MegaNekko her glasses back on her]] and says, "There's Quinn." before they share their FirstKiss. Then in the episodes after this they are all over each other; making out very frequently, being intimate, slow dancing. However, these two are actually very good together, give off a great OppositesAttract vibe, and have a lot of chemistry to the point where a viewer might wonder why the writers didn't start building them up earlier. Quinn and Logan both [[LampshadeHanging lampshade]] how weird it is that they are together, and admit that they are embarrassed to be dating and hide it from the other characters and when they tell Michael about their relationship, he thinks they're joking.
** Zoey and James. In the episode that introduces him everyone instantly loves him, except Micheal and Logan, who still miss Chase. So after everyone thought they were dating because they interacted, the the episode ends with them getting together despite having no chemistry. Sort of {{deconstructed}} as she later realizes she doesn't actually love him. It was still terribly executed and lead to the series' SeasonalRot.
* Hawkman and Hawkgirl in the two-part ''Series/TheFlash2014'' and ''Series/{{Arrow}}'' special (which serves as a lead-in for ''Series/LegendsOfTomorrow'') have absolutely no onscreen chemistry together. Hawkgirl even acknowledges this to Cisco, whom she'd been dating prior to her remembering who she was (and who was still very much in love with her) but says that she should be with Hawkman BecauseDestinySaysSo.
* Happens a few times on ''Series/TheWalkingDead'', but the most prominent example is [[spoiler: Carol and Tobin,]] who share a kiss for some inexplicable reason, despite only speaking once in the previous series.

[[folder:Tabletop Games]]
* Invoked in ''TabletopGame/ChangelingTheLost''; one of the more powerful breeds of Hobgoblins is a race known as the Crimson Weavers, faeries of the Moirae breed who appear as [[MiniatureSeniorCitizens diminutive ancient Asian women and men]] with strands of red string dangling from their fingers. As their name implies, they are born from the aspect of Fate that gives rise to the RedStringOfFate, and they have both the power to connect others with that self-same Red String and the drive to do so. The thing is, this being the [[CrapsackWorld World of Darkness]], they are ''not'' infallible and, indeed, often tend to completely screw things up by forcing people to be together, just because they "looked so right" through their permanent ShippingGoggles. Thus leading to the trope in question... sometimes literally; couples arranged by Crimson Weavers have been known to end in suicide and/or murder, or complete insanity. Crimson Weavers never take responsibility, see themselves as responsible or consider it their fault; they merely gave each person a guaranteed soul mate, it's the people involved who refused to accept that.

* In ''Theatre/LesMiserables'', Marius and Cosette fall in love having only seen each other once, for a few seconds, in the street. The next time they meet they're declaring undying love for each other (A Heart Full Of Love), much to the despair of poor Eponine who's fancied Marius for ages. This is made worse by the AdaptationDistillation: in the book, they know each other for much longer before either shows any romantic inclination.
* ''Theatre/MeasureForMeasure'' is (or could be, depending on how it's read) a particularly bad example of this: Duke Vincentio proposes to Isabella at the end even though they've known each other for about two days and the entire plot revolved around Isabella not wanting to give up her chastity and monastic life. Of course, she never explicitly says yes, so a director can play this any way he wants. This is one of the many clues that make people think this play is problematic on purpose -- that Shakespeare was trying to make his viewers uncomfortable. It's technically a comedy (it has a wedding at the end), but it's a damn squicky and creepy comedy.
* Creator/GilbertAndSullivan are quite fond of these, mostly involving the chorus at the finale, but not always:
** Played for laughs in ''Theatre/ThePiratesOfPenzance'', with Frederick and Mabel's ridiculously quick romance. Not quite LoveAtFirstSight, but still. Also, the daughters and pirates pair up.
** ''Theater/{{Ruddigore}}'' frequently ends with the newly-revived ghosts marrying the chorus of bridesmaids. Never mind that they never interacted, and most of the ghosts have been dead for centuries, it's more important to give everyone a wedding!
** ''Theatre/TheSorcerer'' takes the cake, though, as it's due to the LovePotion that everything happens.
** Averted in ''Theatre/{{Iolanthe}}''. Although everyone gets married at the end, the Fairies have had the hots for the Peers all the way through Act II, the Queen is dotty about Private Willis and finally doesn't have to deny it any more, the Chancellor gets his long-lost wife back and Strephon and Phyllis are able to be together after all. So for once absolutely every pairing is justified.
* ''Theatre/RomeoAndJuliet'' is the TropeCodifier and possibly the {{Trope Maker|s}}. While it's considered one of Shakespeare's best plays as well as one of the greatest written works ever, let's face it; the title characters are the textbook definition of this. They fall in LoveAtFirstSight and are immediately making out at the Capulet's party. Okay, not so bad. However, Romeo goes from {{wangst}}ing over breaking up with Rosaline earlier ''that afternoon'' to being engaged to marry Juliet ''later that night'', and Juliet is so in love with him that she's willing to fake her own death to keep from marrying Paris. Lampshaded by Friar Lawrence when he says "Young men's love lies not in their hearts but in their eyes." A popular interpretation is that part of the tragedy is these two kids mistaking their shallow youthful lust for true love, and that the adults who ''should'' be helping them realize that are too preoccupied with their own petty, immature squabbling, ultimately leading to the two's deaths.
** The poem on which ''Romeo and Juliet'' is based, Arthur Brooke's "The Tragical History of Romeus and Juliet," had its action occurring over the course of nine months--Shakespeare cut it down to five days. Brooke's poem isn't very good, but at least it has a believable timeline for falling in love.
* ''Theatre/TheTempest'' might be even worse about this, with Ferdinand and Miranda. They declare their undying love for one another a full act before they even know each other's names, and never give any real justification besides BeautyEqualsGoodness. It's even more obvious when Prospero is suspicious of Ferdinand and tests his love, but a few more proclamations of love and devotion later (none of which go much deeper than "but I ''really really'' love her"), and he pronounces them a perfect couple.

[[folder:Video Games]]
* ''Franchise/AloneInTheDark'': The rather forced relationship that develops between Carnby and female companion/sidekick Sarah Flores in the 2008 ''Alone in the Dark''.
* ''VideoGame/{{Aveyond}}'':
** ''Ahriman Prophecy'' has Devin marry Princess Alicia Pendragon, even though Alicia is an OptionalPartyMember who barely has anything to do with the plot, and could only be recruited if the two main characters, [[FanPreferredCouple Devin and Talia]] completes an optional side quest in Candar.
** Rhen from ''Aveyond 1'' canonically ends up with Sun Priest Dameon. Most of the romantic interactions between him and Rhen occurs during optional dialogues in the Sedona manor, which hardly count as "chemistry" because it often sounds more like Dameon being a flirt, rather than showing genuine interest.
** In ''Aveyond 3'', [[WordOfGod Amanda]] reveals Edward/Stella to be canon, when the canon prologue of the third chapter has Edward about to marry ''Mel''. Mel's canon love interest doesn't even show up in the games.
* [[Creator/QuanticDream David Cage]] has gained a fair amount of notoriety for this trope:
** ''Videogame/BeyondTwoSouls'' generally tries to push Jodie with her CIA handler Ryan Clayton no matter the decisions you have her make. Most notable is how the game goes from the first time they meet, in which he's incredibly insensitive towards her and basically forces her into the CIA to a scene taking place roughly more than a year later, where Jodie states that she's in love with him. Similarly, it's possible for Jodie to end up in a romance with Jay in the ending despite only knowing him for about two days. This becomes PARTICULARLY annoying if you've shut down Ryan at every opportunity and [[spoiler:chose to die]]. Jodie will STILL act like she has feelings for him.
** In ''VideoGame/{{Fahrenheit}}'', Carla is an NYPD police officer pursuing Lucas Kane, who she believes to be a psychotic murderer. Some developments in the case eventually lead her to doubt his guilt, but she remains suitably skeptical and logical. She finally meets Lucas at [[spoiler:the grave of his long-time girlfriend Tiffany, who had died ''two days before'']]. Within about a month, Carla has risked her job and her life to help Lucas, begun to trust him implicitly without her previous intelligent questioning, declared her love for him, and gotten herself knocked up with his zombie child, ''all entirely offscreen''. And this happens on all three endings, including the ''good'' one. Not to mention you can actually get back together with Tiffany without averting any of this.
** And in ''VideoGame/HeavyRain'', we have Ethan and Madison. This one has the benefit of being ''sort of'' optional in that you can turn her down, but Madison spends most of the game nursing Ethan back to health after the Trials and believing, for very good reasons, that he may be the Origami Killer with a very deep-seated mental illness. The clock is ticking on Shaun Mars's life, Ethan is emotionally and physically wounded, Madison hasn't slept in days due to the insomnia caused by PTSD, but as part of Quantic Dream's celebrated history of completely inappropriate and nonsensical sex scenes, Madison decides this is the perfect time to get horizontal. With an injured man who openly admits he might be a serial killer who drowns little boys.
* ''VideoGame/{{Catherine}}'' actually punishes players who attempt to put this trope into practice. Throughout the game, your interactions with Catherine and Katherine will affect a meter--acting like you're in love with Katherine tips it to the Order end of the meter and the same goes for Catherine with Chaos. However, through a series of questions near the end of the game, it's possible for Vincent to choose either girl [[TakeAThirdOption (or even neither)]] no matter what your position on the meter is. ''But'', the game checks the results of your questions against the meter, and if it doesn't match up--for example your answers suggest that Vincent wants to stay with Katherine, even though the meter reflects that he's acted more in love with Catherine--you will get a bad ending. (On the opposite end of the scale, if your answers perfectly match up with Vincent's meter, you get a "true" or better-than-good ending.)
* Similar to the ''Beyond: Two Souls'' example, Kid and Serge in ''VideoGame/ChronoCross''. Kid is a unique example in that the player isn't initially forced to take her into the party. It's entirely possible to refuse her at several points and opt not to come to her rescue, ''but she shows up at all the major plot points anyway''. The story justifies it by saying that she just follows you around because you're tough and can clear the way for her, but it mostly means she shows up at exactly the right time to [[SpotlightStealingSquad make a dramatic speech and run ahead of you]], only to [[RescueRomance end up imperiled]] and need to be rescued-- ''at the player's discretion''.
* ''Franchise/FinalFantasy'':
** ''VideoGame/FinalFantasyVII'' will always have Cloud ending up very close to Tifa and having a DidTheyOrDidntThey scene with her under the Highwind. However, the game also has an affection system which allows the player to be kind to her or horrible -- and while Cloud certainly gets a lot of scripted scenes with her in which he states his affection, he can end up bullying her much of the rest of the time. If the player chooses to do this, Cloud's dialogue in the eventual scene changes to come off as distant and bored, but he'll still wake up in her arms the next morning.
** Squall and Rinoa's romance in ''VideoGame/FinalFantasyVIII'' can come off this way, as Squall's extensive emotional issues keep him in heavy denial about his feelings for the first two discs of the game until Rinoa's coma forces him to start confronting them. Player choices may exacerbate this further: by not taking Rinoa along as a party member and/or missing certain plot events which provide CharacterDevelopment for the pair, and by refusing the occasional dialogue options indicating that Rinoa's efforts to coax Squall out of his shell are making headway, the player can bypass much of the buildup of the relationship, causing Squall's sudden fixation on Rinoa in Disc 3 to seem as though it comes out of nowhere.
** A similar example can happen in ''VideoGame/FinalFantasyX'', which clearly intends to ship Tidus/Yuna, but inexplicably includes a relationship system that includes Yuna, Lulu, and Rikku. Thus a number of scenes can take place implying Tidus' attraction with one of the other two girls before the game takes over and pushes him back to Yuna instead. While not nearly as extreme as the Rinoa example, as Yuna and Tidus have plenty of mandatory scenes throughout the story that build them as a couple and Yuna is always in the party when the game needs her to be, it can feel a bit ham-fisted if the player chased one of the other two women and yet Tidus always ends up with Yuna, Lulu always ends up with Wakka (which comes out of nowhere in its own right), and Rikku always ends up in the sequel single and refusing to talk about her relationship with Gippel.
** ''VideoGame/FinalFantasyXV'': Noctis and Lunafreya have a relationship that is seen by fans as poorly drawn out and unfocused. This couple first met when they were kids after Noctis had a near death experience and they had not met again until the events of the actual game when they get betrothed as a result of a treaty between Lucis and Niflheim that turned out to be a sham. Even then, Noctis only interacted with Lunafreya before the eighth chapter through a notebook that they kept delivering notes to each other with Luna's dog, Umbra being the carrier. Noctis doesn't even meet up with Luna again until Ardyn murders her. The games epilogue even shows them after they died, dressed in their wedding clothes and sharing a kiss.
* ''VideoGame/FireEmblem'':
** In ''VideoGame/FireEmblemGenealogyOfTheHolyWar'', Finn and Raquesis are nearly an OfficialCouple; Finn gets a conversation with Raquesis' daughter in the second generation if he's her father[[note]]not true for all potential fathers[[/note]], and they're one of the pairings in the Oosawa manga adaptation. In ''VideoGame/FireEmblemThracia776'', it's strongly implied that Finn and Raquesis were in love and that Finn continued to search for her. The only hitch is that during the time both characters are playable in ''Genealogy of the Holy War'', they have no conversations together, not even if they're married in Chapter 5 (admittedly, Finn isn't there for plot reasons). It's like the devs somehow forgot to put it in there.
** ''VideoGame/FireEmblemAwakening'' mostly averts it -- you can only get your characters married after they spend a lot of time on the battlefield together (which can '''never''' be less than four battles, and will usually be more), watch multiple conversations that give reasons at least somewhat believable for the two falling in love (with more conversations implied), and even then you have to make the final push for the characters to get married yourself. Except Chrom. For storyline and mechanics reasons, he gets married to whichever one of his prospects he has the most support points with after Chapter [[spoiler:11]]. One of the characters Chrom can marry, Olivia, is made playable right at the beginning of that chapter. So if Chrom has no support points with any of his other prospects or they are unavailable due to permadeath or marrying someone else, he can marry Olivia very shortly after meeting her with all of ''one'' support point -- not even enough for a C-Rank conversation! There's also a chance the player could get to the point of Chrom's marriage in the game and not have ''any'' of his potential brides still available, in which case he'll marry a random villager the player never hears from again. This even gets {{lampshade|Hanging}}d:
--->'''Lissa:''' "Turn my back one minute and you're married. The next minute? A baby!"
*** Chrom and Olivia are an interesting case in that their C-A Supports actually do give them a nice chemistry and groundwork for romance, but they can only be attained during gameplay after he's married ''anyone'' else. In the event he marries Olivia it's quite feasible for these conversations (and the S-Support) to have taken place some time between Chapters 11 and 12, so this lessens the LastMinuteHookup nature of the pairing, but it does leave the player feeling cheated they weren't allowed to ''see'' this take place like with Chrom's other Support options.
*** The game also makes an effort to HandWave why Chrom is suddenly forced into marriage (besides the plot reason of [[spoiler:Lucina needing to be born to set up "Marth's" reveal as future her]]). He'd recently ascended to ruler of Ylisse and was the last with a rightful claim[[note]]There is his sister Lissa, but she doesn't bear the Mark of Naga, leaving her legitimacy [[SuccessionCrisis open to dispute]], though her kid from the future has the mark, confirming her as legit, it's revealed optionally much later[[/note]], so there was popular pressure for him to take a wife and produce a child to visibly secure the nation's future.
** While ''VideoGame/FireEmblemFates'' mostly averts this as well-you have to pair the prospective couple in battle together lots of times, watch conversations that make the pairing somewhat plausible, and have to physically ''confirm'' that you want this couple to get married-some of the supports are so oddly written that this trope can only really be in play. Especially egregious are the Avatar's supports [[spoiler: with his/her own ''siblings''. Yes, granted, it turns out on both sides they're NotBloodSiblings, but still, given that half of them grew up with the Avatar as a sibling and the other half (aside from Ryoma, who knew the truth the whole time) thought the Avatar was their blood relative, it's a bit hard to believe that they've 'always been in love' with the Avatar.]]
* The ''VideoGame/GearsOfWar'' games have Marcus and Anya, who have so little chemistry it hurts. They barely interact, and when they do, there's nothing particularly romantic about it. It doesn't help that the games tend to be light on the characterisation side, making these two's romance just awkward every time it appears. In the games, Anya has very little personality beyond being a caring person, while Marcus is the typical aggressive screaming soldier (he may even be the new poster boy). While this can be justified by the fact that there is a world-ending conflict going on, it doesn't change that we're supposed to swallow that these two apparently love each other.
* ''VideoGame/GrandTheftAutoSanAndreas'' has this as a plot element. Meet the right circumstances and the gal will fall head over heels with you. At least with the first one it's rescuing her from a house fire (that you started). With others it's simply that you have six pack abs or she has a chubby fetish.
* ''VideoGame/GrimFandango'': Manny escorts Meche to the Underworld, briefly talks about her life and is suddenly so in love with her that he spends the next three years searching for her, ignoring any other woman that has an interest in him.
* ''VideoGame/HarvestMoonAWonderfulLife'' has this happen if you don't marry anyone by the end of the first year. If such a thing happens, you end up proposed to by whichever marriage candidate has the highest affection, regardless of how little it is. However, this is averted if it's Nami, who agrees to marry you so she can stay in Forget-Me-Not Valley, since she's otherwise forced to leave because of a lack of money.
* ''VideoGame/HyruleWarriors'': A common criticism of the story is how the heavily inconsistent ReincarnationRomance angle of Link and Zelda's dynamic is suddenly blown up to a guaranteed thing between them, despite the fact that there are multiple titles in the series where Link and Zelda meet and barely form a relationship (nevermind a romantic one), and even here, they have maybe two or three interactions tops that push the ImpliedLoveInterest label on them. A possible explanation for this is that the only people who comment on their "fated union" are Cia and Lana, whom both have story reasons to invest in that idea; Cia uses it as an excuse to [[MurderTheHypotenuse lash out in jealousy]] and [[TheVamp seduce Link over to her side]], while Lana plays it up as a reason to cajole herself to stop pining for Link and start focusing on her duties again before [[spoiler:she too has her affections turn toxic and used against her]]. Though that line of reasoning does bring up the question of why Lana would even need to maintain the mantra in the first place if she still had a chance with Link.
* The ending of ''VideoGame/KingdomHeartsII'' and the credits of the ''2.8 Final Chapter Prologue'' HD collection indicates that Roxas and Naminé, Nobodies of Sora and Kairi, are intended to be a romantic pairing. The problem is that whereas Sora and Kairi share a history and close friendship, Roxas and Naminé have only a few interactions that are largely based around plot exposition - Roxas himself shows much more closeness with Hayner, Pence, Olette, Axel and [[VideoGame/KingdomHearts358DaysOver2 Xion]] than he ever does with Naminé, so pairing them together comes out of left field and only seems to be on the basis that if Sora and Kairi are in love then their Nobodies have to be.
* ''VideoGame/TheLastStory'' suffers from this. The player is supposed to believe that Zael and Calista fall in LoveAtFirstSight and that that's a good enough reason for them to be together. While this could very well be the case, the problem is that there simply aren't enough scenes that ''show'' them interacting together. Meanwhile, the BetaCouple ([[spoiler:Lowell and Syrenne]]) inverts this. They similarly don't get many scenes together but they ''do'' have a lot of in-game banter and a long history together which helps to affirm that there is indeed a romantic attraction there.
* In ''VideoGame/Left4Dead'', Francis has seen Rochelle for a grand total of three seconds, they want each other (although in a snarky way). Ellis and Zoey could be an example, but Zoey won't always return the sentiment.
* Dart and Shana in ''VideoGame/TheLegendOfDragoon'' hook up at the end of Disk 2 with very little build up. While Shana clearly has feelings for Dart from the beginning, Dart states several times that he doesn't see Shana as a romantic interest at all[note]When asked if he held Shana's hand during a "date", Dart responds that she's not a little kid he has to keep an eye on[/note] and considers her his baby sister. Then in the last ten minutes of the second disk, Dart declares that he loves Shana as well and they share a kiss under the stars. That Shana gets PutOnABus early in the next disk for the rest of the game doesn't help.
* In ''VideoGame/TheLegendOfSpyro'', Spyro and Cynder go through the trilogy not showing any romantic interest in each other and then suddenly in the climax of the last game, Cynder says she loves him. The explanation for this is that Spyro and Cynder weren't supposed to hook up but a part of the fanbase wanted them to, so they decided to ThrowItIn.
* The hero of ''Mad Paradox'' ends up married and raising a family with a completely nondescript girl he's rescued from the BigBad. She only appears once in the beginning (in the background of a vision) and once at the end (after you've defeated the BigBad). And they treat this as some sort of grand romantic ending. Meanwhile, the hot green-haired {{True Companion|s}} girl who's accompanied you for most of the game through good and bad, battling evil and putting it on the line for you...just sorta wanders off with a pithy "It was fun, bye-bye". Most unsatisfying ending ever.
* ''Franchise/MassEffect'' gives us Liara T'Soni, [[ImpliedLoveInterest who is constantly pushed as the canon love interest]] of [[PlayerCharacter Shepard]]. In [[VideoGame/MassEffect1 the first game]], simply being polite to her can easily trigger a romance with her (complete with the game's most explicit sex scene), and no matter how rude you are toward her, she is treated in [[VideoGame/MassEffect3 the third game]] as Shepard's best friend.
* ''VideoGame/MetalGear'':
** In ''VideoGame/MetalGearSolid'' Snake and Meryl have a scene where they meet, they separate, then have another scene later on that expands a bit on Meryl's character. Almost immediately after is the Psycho Mantis fight, at the end of which Mantis claims out of nowhere that Snake has a large place in Meryl's heart (ironically coming ten minutes after she herself claims to have had psychotherapy to destroy her interest in men while in training - so much for that). They have another conversation, then Meryl is shot and she's not seen again until the finale, where they're suddenly having a romantic moment and riding off into the sunset. However, Meryl is a complete no-show in the next game (the only hint of her even still existing is a purely optional Codec conversation between Otacon and Snake, where the latter comments that he has "had enough of tomboys" in regards to Olga Gurlukovich vaguely reminding Otacon of Meryl), and in ''[=MGS4=]'' it turns out the two broke up rather quickly afterwards.
** ''VideoGame/{{Metal Gear Solid 2|SonsOfLiberty}}'' has a rather infamous example with Raiden and Rose. Rose is introduced as Raiden's girlfriend, and most of their conversations are about their relationship, ranging from how SickeninglySweethearts they are to her being a nagging girlfriend asking him to remember an important date. By the end, this is actually justified, as it turns out [[spoiler:she's a spy for [[AncientConspiracy the Patriots]] who has changed her looks and personality in order for him to fall in love with her, with much of their relationship being scripted on her part]]. The ending has them both [[spoiler:swear to help each other discover their true selves]] and form a more genuine connection, but that doesn't stop most players from being irritated to hell and back by the forced nature of their relationship.
** ''VideoGame/{{Metal Gear Solid 3|SnakeEater}}'' has similar issues with Snake and EVA, though it's less prominent as EVA is a radio contact for most of the game so at least they have more than a few conversations. Completely justified as [[spoiler:EVA is a spy and deliberately throwing herself at Snake to manipulate him]].
** In ''VideoGame/{{Metal Gear Solid 4|GunsOfThePatriots}}'' the relationship between Otacon and [[spoiler:Naomi]] came out of nowhere and was poorly handled whenever it cropped up. Somewhat justifiable, as it's later revealed that [[spoiler:Naomi was throwing herself at him in order to advance her and Ocelot's goals. But then it's implied she did legitimately have feelings for him... post-mortem. Go figure]]. Also, Otacon has a habit of reacting to any overtures of friendship and kindness by immediately dedicating his body and heart to the giver (see also his completely one-sided attraction to Sniper Wolf in the first ''Metal Gear Solid'')... a not uncommon trait among [[spoiler:[[RapeAsBackstory victims of child sexual abuse]], as he's revealed to be late in ''[=MGS2=]'']].
* ''VideoGame/MonsterRancher 4'' is the same deal as ''VideoGame/FinalFantasyX'' above: There's a relationship system with the various female shopkeepers which also lets you get discounts, but at the end you end with your aide no matter what.
* Jumin's route in ''VisualNovel/MysticMessenger''. While every romance route in this game suffers to some extent from taking place over only 11 days and having to be sidelined at times for non-romance plot developments, Jumin's gets the worst of it. Basically, he goes from being so disinterested in women that he was rumored to be gay to being so obsessed with the female player character that he's displaying ''wedding rings'' as his profile picture after less than two weeks of knowing her, before they've even gone on a proper date! Not only that, but while Zen and Yoosung act flirty with you from Day 1, Jumin doesn't even begin to show clear romantic attraction to the player character until they meet in person on Day 5 which means that he's seriously contemplating marriage with her after only ''six'' days of actual romantic interaction with her.
* ''VideoGame/NeverwinterNights'':
** In the last act of ''Hordes of Underdark'', there is a sleeping angel who awaits his true love. When you later find the Knower of Names, you can pay an extravagant sum to find out who his true love is -- if you're female, there's a chance it's you. If you go along with it, the epilogue will talk a bit about your subsequent passionate romance, none of which will ever happen during play. Turns out quite silly if the Sleeping Man's true love is Evil!Aribeth.
** In the original campaign there's Aarin Gend, the spymaster. If you're female, you can talk to him on multiple occasions in act 2, and he'll talk about his troubled and criminal past, how Nasher took him in, and the woman he fell in love with but lost. You get a tacky heirloom amulet after one conversation and it gets upgraded a bit in a later one (nothing you'll have much use for, though). Then your journal outright states that you're Aarin's ''lover''. Sorry, did I miss something?
* ''VideoGame/NeverwinterNights2'':
** The romance between the male Spirit Eater and Safiya in ''Mask of the Betrayer'' is slightly better-done than most examples, but the whole ReincarnationRomance element pushes it into this territory. Very little build-up, minor and completely optional flirtatious remarks, and just like that... instant romance.
** It happened in the original campaign, too, with the DesignatedLoveInterest for a female Knight-Commander, Casavir. Even if you rarely spoke to him, and expressed the exact opposite of his opinion when you did, he would ''always'' want to jump your bones, regardless of your species, class, or alignment. You could be a Chaotic Evil half-orc blackguard with 6 Charisma and Intelligence who bludgeons orphans to death, and he'd still give it a shot if you were female. That last one is particularly jarring, seeing he's a [[LawfulStupid paladin]]... is it any wonder the female fans [[FanPreferredCouple prefer]] [[MrFanservice Bishop]]? [[TheScrappy For all her problems]], Elanee will at least give up if it's clear you don't like her. This is possibly caused by cut content.[[note]]There were originally four planned romances for the game: Elanee, Casavir, Neeshka and Bishop. Neeshka and Bishop are considered cut romances, since in Neeshka's case there's very little there beyond a hint of her attraction to the Male PC, while Bishop's doesn't really get to the 'admitting that they like each other stage'. However, looking through the unused files left in the game, as well comparing what's in the game, it can be seen that there was a lot taken out of the Casavir romance as well. As to whether the suddenness of Casavir's attraction for no discernible reason was something caused by the cut content, well we'll probably never know.[[/note]]
* ''VideoGame/ObsCure'' has a few couples in the game, and most of them are standard high school and college romances, or one-sided but believable crushes. However, Stan gets one with Shannon. The two of them have no interaction with each other [[spoiler: until Stan helps her kill a mutated Kenny]]. All of a sudden, they're making out.
* ''VideoGame/RadiantHistoria'' has a couple that goes through one via RomanceSidequest. This one has some justification on one side, since the echo effect between timelines means the time-traveling male half has unknowingly been charming the female half twice over the entire time without realizing it. His reciprocation is genuinely out of the blue, however.
* ''VideoGame/ResidentEvilCodeVeronica'' has Claire and Steve, both which were prisoners on Rockfort Island. Their first encounter has Claire pointing a gun at Steve due to him mistaking her for a zombie and shooting at her, causing her to angrily scoff at his apology. As the story progresses, it's clear that Steve starts developing a crush on Claire and even makes a few passes towards her, but she brushes it off and, even as she warms up to him, seems to view him as nothing more than a new friend with no noticeable romantic intent. Near the end of the game, Steve gets captured, transforms into a monster, and nearly kills Claire until his humanity wins through, though Alexia fatally wounds him. Steve apologizes for the trouble he put Claire through and then dies, causing Claire to bawl her eyes out over a young man that she didn't seem to care too much about for most of the game.
* ''VideoGame/TheSecretOfMonkeyIsland'' has this happen to the OfficialCouple of Guybrush and Elaine. They meet once (after he's just broken into and trashed her mansion no less!) have a brief conversation then, when they meet again, they're suddenly acting like SickeninglySweethearts and declaring their undying love! The whole thing is played very tongue-in-cheek like the rest of the game so most players don't mind much.
* In ''VideoGame/ShiningForce II'', at the very end of the game, it's revealed that [[Disney/SleepingBeauty the Princess can only be awakened from her magical sleep by a kiss from her true love]]. An NPC then informs the main character that they're talking about him. Which is good, because until that moment, there's been no indication that the Princess would have been able to pick him out of a line-up, let alone been in love with him. The princess gets one line appreciating the hero's bravery, then literally right afterward is pulled into the Demon World and stays there for the next 4/5 of the game, only appearing again after the BigBad is defeated and the kissing matter comes up as mentioned.
* One of the endings of ''VideoGame/SilentHill2'' shows James suddenly deciding that he had strong feelings for [[spoiler:Maria]] and wants to be with her. This comes out of nowhere because, even though [[spoiler:Maria]] flirts with James constantly throughout the game, James always responds to this behavior with confusion and irritation. It makes more sense when you realise that [[spoiler:she is just a version of his wife that Silent Hill created.]]
* ''VideoGame/SoulBlazer'' suddenly springs one between Lisa, a minorly important NPC in the game's first location, and Blazer, the protagonist. After leaving Grass Valley, where Lisa lives and was awoken by Blazer to progress the plot, she is no longer [[OutOfFocus focused on]] for a good chunk of the game. In the penultimate area, Lisa is brought back on screen again for a scene and [[spoiler:after watching her father die in front of her,]] she makes it clear to Blazer and the player that she has fallen in love with him. TheStinger of the game then implies that, despite a year having passed since the final battle, Blazer still has feelings for Lisa. Blazer being a SilentProtagonist and no dialogue option appearing that would imply romance, the fact that the two characters are implied to end up together, now both as regular humans, can come across as very hastily written.
* In ''VideoGame/SpyroAHerosTail'', Ember had a clear crush on Spyro, which carried over to Shadow Legacy. Then an armadillo named Bandit saw her, immediately fell in love with her and had Spyro deliver a love letter to her. When Ember got the letter, she immediately dropped her crush on Spyro and fell for Bandit, even though the two barely interacted and would not again for the rest of the game.
* The ''VideoGame/{{Tales|Series}}'' series:
** ''VideoGame/TalesOfEternia'': Throughout most of the game, Keele is cold, rude, and [[FantasticRacism flat out racist]] to Meredy. She is initially kind to him, but faced with constant rudeness from him begins to withdraw from him - Until [=9/10ths=] of the way into the game, where Keele suddenly begins to warm to Meredy and decides to [[spoiler: remain in the world of Celestia to be with her.]] While in the Japanese version there are some skits that show Keele's defrosting attitude earlier on, these were removed in the English version, making the pairing come off as PairingTheSpares.
** ''VideoGame/TalesOfSymphonia'': The player can invoke this if they bungle Colette's RelationshipValues and then chooses to [[spoiler:kill Zelos off to get Kratos back in the party,]] since Colette is the default love interest and the scene where you choose which ending makes you reject everyone in order to [[spoiler:pick him]].
** ''VideoGame/TalesOfGraces'', from a series that's normally really good at averting this trope and playing romances subtly. A lot of people were unhappy with the Asbel/Cheria romance for this reason, especially after ''Graces f''. In the main game, Asbel seems to be [[ObliviousToLove ignorant of Cheria's crush on him]]. But in the Future arc, he's suddenly blushing and stammering around her like an idiot. The extremely vague development in the original game coupled with the awkward, unprecedented and shoehorned romantic scenes in the Future arc turned a lot of people off. It doesn't help that Asbel/Sophie and [[HoYay Asbel/Richard]] have a lot of fan support and at least a bit of subtext each.
*** This romance also contradicts some character development in the main story. Towards the end, Cheria acknowledges that, while she has feelings for Asbel, he hasn't shown any sign of reciprocating. So instead of hanging around Lhant brooding over him, she quite sensibly decides to go travel the world with the Doctors Without Borders-style organization she helped found. The Future arc ignores that character development by having the two of them end up together anyway.
** Deconstructed in ''VideoGame/TalesOfTheAbyss''. Legretta loves the BigBad... A love mandated by BecauseDestinySaysSo, and she ''hates'' it because she wants to fall in love by her free will. Thus, she wants to destroy the world's concept of destiny. Fortunately for her, the BigBad wants the same thing so she has an actual reason to follow him.
** ''VideoGame/TalesOfXillia'' took the little ''Graces'' fiasco above and turned it up higher, when it comes to Jude and Milla. Their supposedly romantic scenes come off as rather awkward [[PanderingToTheBase fan-pandering]]. Neither of them admits anything out loud, making their status as OfficialCouple rather questionable. This is not helped by their voice actors having very little chemistry and certain scenes making use of originally subtext-laden dialogue LostInTranslation, making the English dub's version even less believable. [[VideoGame/TalesOfXillia2 The sequel]] decided to start its pandering, again, in the later Character Chapters for Jude and Milla, suddenly adding ''a lot'' of too-obvious nudges at the two, including scenes that are supposed to be romantic, but once again fail due to the previous problems, or feel out-of-place for what's currently going on.
** ''VideoGame/TalesOfXillia2'' has an implied case with Ludger and Lara Mel Marta in the Good Ending. It is unclear how they got together in the other dimension, but were implied to be HappilyMarried and had Elle. Over the course of the game, there's the revelation that Elle comes from a fractured dimension that is a few years ahead of the prime one, meaning [[KidFromTheFuture she hasn't been born yet]]. In the Neutral Ending, when Ludger hears Lara Mel Marta is here to see him, he rushes towards her and it's implied that they will fall in love. To the player, it makes their relationship seem to serve no purpose, other than to have Elle be born into the prime dimension.
* ''VideoGame/WildARMs2'' has a ridiculous example of this. If you pick up optional character [[OurVampiresAreDifferent Marivel]], she suddenly effectively shacks up with Tony when everyone else is having romantic scenes that make sense. Tony is a minor NPC, and they didn't even share a single line of dialogue before suddenly being set up as a couple.
* ''VideoGame/{{Yesterday}}'' has this with John and Pauline. Much of their romance happens off-screen, with the player sort of joining InMediasRes to their relationship. This may be mitigated a little bit with the fact that prior to John's amnesia, they were in love with each other.

[[folder:Web Comics]]
* ''Webcomic/ElGoonishShive'' has a pretty clear example in Ashley and Elliot. It takes ''11'' strips ([[http://www.egscomics.com/index.php?id=1776 here]] to [[http://www.egscomics.com/index.php?id=1787 here]]) to go from introducing each other to asking each other out. The next time we see them together, they're on a date that has an entire storyline dedicated to it. In the commentary of [[http://www.egscomics.com/index.php?id=1594 this strip]], Dan explains that Tedd and Grace also fall into this category, and that he wishes he had made the start of their romance more gradual. He explains that he had always hated "Will they or won't they?" plots and that he was going to be different, but that he may have ended up going too far in the other direction.
* The first half of ''Manga/AoiHouse'' seems to build up to a will-they-or-won't-they tension between Alex and Elle, only to throw it out in favor of pairing him with fan favorite [[GenkiGirl Morgan]] in the second half, despite Morgan's crush being infantile at best and Alex ignoring her for most of the series.
* Played with in ''Webcomic/{{Homestuck}}'': John and Vriska have known each other for all of six hours before she starts developing a crush on him. However, after a year's TimeSkip, someone brings up the subject to John again... and he proceeds to go over all the problems that commonly accompany this trope, and concludes that ultimately, they'd have to know each other far longer before it could really mean anything. Indeed, during the TimeSkip, Vriska [[spoiler:dated an [[BadFuture alternate version]] of John for a while, but since they were both [[OurGhostsAreDifferent dead]], they had infinite time to get to know each other. And then their relationship fizzled out anyway]].
* Rhonda and Quinn in ''Webcomic/KevinAndKell''. Quinn literally showed up for a single storyline, as a threat to Lindesfarne because she was in an arranged marriage with him that she couldn't get out of. So, even though a storyline had passed very recently that revealed that Rhonda and Edgar had completely patched up their relationship problems and Edgar was now a good, attentive boyfriend willing to humiliate himself for Rhonda, for the convenience of the Lindesfarne plot, he suddenly underwent AesopAmnesia and snapped back to nothing ever changing. This gave Rhonda an excuse to dump him and marry Quinn, as the story told us they'd been having an online relationship for years (this was the first time it ever came up). Also, the comic conveniently ignores that for all of Edgar's flaws, Rhonda was basically cheating on him the entire time they dated. The storyline was also used to [[PutOnABus put Rhonda on a bus]] with a massive whimper. While Rhonda made a cameo or two at Lindesfarne's wedding, Quinn the plot device didn't show up until the next Rhonda-centric storyline about whether to take a job at Herd Thinners or Kell's startup company.
* ''Webcomic/LasLindas'':
** [=SoulKat=] apparently decided that Miles and Rachael needed to be shoved together as soon as possible, with little other than ID holding him back from doing it within a few pages. The part with Miles showing Rachael his junked plane, with Rachael reacting inexplicably well to Miles calling her pet-names and sharing his responsibility-dodging dreams with her, was the ''toned down'' version--the original, according to [=ID=], was filled with juvenile flirting and completely unsubtle double-entendres from both characters. As Rachael has previously given every indication of absolutely ''despising'' guys like Miles, and as Miles has not shown a single sign of miraculously becoming the type of man she'd want to spend her life with, this trope is in full effect as she's steadily {{Flanderiz|ation}}ed into a stereotypical {{Tsundere}} to facilitate their pairing. On the forum, [[WordOfGod despite Chalo himself saying all that's changed is Rachael just hates Miles a tiny bit less]], she's begun adopting [[ItsAllAboutMe his arrogant, myopic worldview]] that she's previously explicitly stated she hates, while he goes on about how close they are and how much time they spend together and refers to her as "[his] girl".
** Randal and Taffy. They barely know anything about each other, rarely interacted with each other at all before this, and still end up ''deeply in love, [[IntertwinedFingers holding hands while gazing into each other's eyes]], and [[TrueLovesKiss passionately smooching]] after one date'', in a scene so overblown and rushed that it feels like a parody of the classic Disney formula. The entire thing makes it seem like it was done solely to get people to stop questioning Randal's sexuality ASAP, and it doesn't help that [=SoulKat=] has [[UnfortunateImplications more than once expressed a desire for people to stop viewing Randal as so much as feminine and shown immense disgust and hatred for a number of fan-favourite same-gender pairings and those who like them.]]
* Almost immediately after Gabby from ''Webcomic/NamirDeiter'' realizes she's over her longtime crush on the main character (a straight girl), she's seduced by her never-before-seen academic partner, Jacinda, and they're joined at the hip from then on. The relationship later falls apart and Gabby hooks up with [[CloudCuckooLander Joan]], a NewOldFlame.
* In ''WebComic/RedString'', Makoto never really gives any reason why he is so obsessed with dating Miharu. The only time we are given insight to this is that he fell in love with her photograph before ever meeting her and the rest of the comic is him basically refusing to leave her alone. Miharu basically falls for him because the story implies she's supposed to, then never really spends any time on developing them as a couple. It's just Makoto doing things like freaking out about losing her and making all her decisions for her and Miharu apologizing to him when he instigates conflicts. Yet even Miharu, after a whole four months of dating him, feels they're in a "serious" relationship in spite of them doing nothing more significant as a couple than sexting and feeling each other up. [[spoiler: The comic ends literally with Makoto quitting his job to date Miharu full time and then after she declares she truly loves him the most, he ''immediately'' proses marriage, which she accepts. The marriage proposal? Originally, it was just the words "Well?" The author got so much flack for how awful this dialog was that she stealth rewrote it, but it still doesn't consist of an actual proposal...and at no point in the entire comic, not even during his marriage proposal, does he ever tell Miharu "I love you."]]
* In ''WebComic/SailorMoonCosmosArc'', despite Chibiusa and Helios never even ''meeting'' in this timeline (thanks to a TemporalParadox), Usagi, Mamoru, and the other senshi are convinced that they will eventually get together. It seems even fate is determined that they'll get together, as Helios still has his connection to Chibiusa [[spoiler: and Chibiusa eventually gets her memories of her past time-traveling incarnation]]. Ultimately, [[spoiler: after Usagi ascends to godhood as Sailor Cosmos]], Mamoru abdicates his claim to the throne to take Helios's place as priest of Elysian so Helios could go to Chibiusa's side, though Helios notes that he's not sure if that's what either of them want. [[spoiler: It's left open-ended whether they get together or not.]]
* Pretty much every couple in ''Webcomic/{{Sonichu}}''. It's made worse by the fact that Chris-Chan considers the romance to be the best part of the comic. This is perhaps {{enforced|trope}} to ensure that none of them get into a HoYay ship.
** Punchy is hinted to have a crush on Angelica. Then he ends up with [[spoiler:Layla Flaaffy]].
** Meanwhile Reginald Sneasel (another Self-insert of Chris thanks to [[spoiler: Him being trapped in the time void]]) tries to get hooked up with Layla, only to end up with Angelica.
*** [[spoiler: Both of the above examples are quickly snuffed out in Issue #11, when Reginald evolves thanks to a razor claw, making him more violent, and Punchy brings home a "Bananasaurus" that mooches off of him and Layla, causing the latter to become enraged at Punchy and break up with him. Afterwards, Layla finds Reginald on the street and immediately shacks up with him, despite no chemistry between them whatsoever having been seen before.]]
** Bubbles is with Blake. They hide their relationship for no clear reason.
** When Reldnahc [[spoiler:is about to be cured of his homosexuality]], there is talk of him getting back together with Kel. There is no mention of this in earlier chapters.
** This is especially true of any of comic!Chris's girlfriends. The most drastic example is Ivy, who is introduced mere pages before ''God Himself'' contacts her and tells her Chris is her true love, which she immediately accepts despite having never met Chris at that point. Then the next mention of her is her death, rendering the strangling pointless.
** Magi-Chan simply announces in Issue #10 that he will fall in love with Silvana. It seemed to serve no purpose other than [[HaveIMentionedIAmHeterosexualToday shutting down]] the common interpretation of him as AmbiguouslyGay - if so, [[DiggingYourselfDeeper it didn't work]], considering that Silvana is [[{{Hermaphrodite}} intersex.]]
* Kyle and the Annihilator of ''The Young Protectors''. Before the comic even progressed past the ''prologue'' the two are all but professing their undying love for each other with Kyle insisting that he wants to have his first-ever sexual experience with the world's most notorious supervillain and has absolutely no doubts about it (in spite of being terrified for years of even having ADateWithRosiePalms due to [[spoiler:his fire-based powers being fueled by emotion, which includes orgasm]]), and said notorious supervillain declaring that he wants to reform himself for Kyle even though he's never had any second thoughts about his supervillain career before. Before this they had a single kiss in a back alley and a single dinner date. Add to that Kyle being only seventeen years old and the Annihilator being ''fifty-eight'' years old, something that doesn't give either of them more than the slightest hesitation... [[spoiler:which was [[IntendedAudienceReaction entirely the point]]. The comic, up through half of the second chapter, was busy {{invok|edTrope}}ing, {{subvert|edTrope}}ing and {{exploit|edTrope}}ing all things LoveAtFirstSight, ''particularly'' of the standard BoysLove variety. Kyle, being a lonely, closeted seventeen-year-old with [[CelibateHero self-enforced celibacy]], lacks much experience with adult life and ''any'' with romance, leaving him extremely susceptible to seduction from the resident ManipulativeBastard, [[DoesThisRemindYouOfAnything who abandons him the moment he gets what he wants.]]]]

[[folder:Web Original]]
* There's a subgenre of PornWithPlot called "Naked In School." It combines sexual shenanigans with a side order of CharacterDevelopment by positing a world where characters have to attend high school nude for a week because [[HandWave reasons]][[note]]The founding story indicated it was signed into law by the President, though said story was also a thriller with a deliberately oppressive attitude to sex-positivity, a [[EarlyInstallmentWeirdness very different tone]] from almost everything that came after[[/note]]. The ExtremelyShortTimeSpan makes this trope tempting, and some stories have fallen for it; one of the worst examples involves two people meeting each other for the first time on Monday and declaring True Love by day's end.
* ''Roleplay/SurvivalOfTheFittest'' v4 pre-game has the "relationship" with [[LonersAreFreaks Jonathan Jarocki]] and [[PerkyGoth Anna Chase]], which seemingly came out of nowhere when they took each other to prom and started dating afterwards. Most of their scenes were kind of awkward, despite the fact that both of them had [[NightmareFetishist rather dark interests]]. This wasn't helped by the fact that one of them (Jonathan) has actually been confirmed to be a self-insert, bringing NoYay into the picture. A lot of handlers expressed disgust at the pairing, which lead to this being fixed once v4 actually started by the two of them having an OffscreenBreakUp.
* The ''Website/{{Neopets}}'' Lost Desert plot was about a cursed prince named Jazan whose only hope of breaking the spell on him was to marry a princess of Sakhmet. When Princess Amira refused, he planned to force her into marriage. Meanwhile, two thieves named Tomos and Nabile learned Jazan's backstory. The latter was especially moved and wanted to help save him from his curse. [[http://www.neopets.com/desert/ldp/index.phtml?chapter=14 Nabile voiced her disapproval at the wedding]], and as it turned out, at that moment it was discovered that she was in fact a descendant of an exiled princess. Having just met, Nabile and Jazan instantly fell in love and were married ''minutes later''.

* Barry and Katya in ''WesternAnimation/{{Archer}}'' get together in season 3 because they're both cyborgs, overlooking Katya's love for Archer and the fact that Barry murdered her (ItMakesSenseInContext), and stay together in a relationship that is dysfunctional from the start.
* Gwen and Kevin in ''WesternAnimation/Ben10AlienForce'': The ship is dropped on the viewer with absolutely no set-up, no basis, no rationality ''in the very first episode''. Kevin almost wrecking his precious car to tell Ben not to be rude to Gwen could be attributed to his BadassDecay, but "I'll follow you anywhere"? At the time of the first airing, and all the while through that first season, the whole thing was a little bit hard to swallow. Since then, plenty of episodes, not only on Alien Force but on the sequel series ''Ultimate Alien'' and ''Omniverse'', managed to develop and add more depth to the relationship, even going as far as to include some retcons on earlier periods in order to make that reunion on the first episode of Alien Force more acceptable.
** Taken to even more extremes with ''WesternAnimation/Ben10Omniverse'' for Ben and Kai. Much like the below example with ''Danny Phantom'', they spent more time making the pairing inevitable than showing ''why'' they should be together [[spoiler:other than one character was their son from the future]].
* Danny and Sam from ''WesternAnimation/DannyPhantom'' were obviously planned to be the OfficialCouple from the beginning, with almost ''[[EveryoneCanSeeIt everyone]]'' remarking on it, if not being an outright ShipperOnDeck, and innumerable [[SheIsNotMyGirlfriend S/he Is Not My Girlfriend/Boyfriend]] moments. The problem is that the writers were so busy making the couple inevitable they never bothered to actually ''[[ShowDontTell show]]'' why they should be together. There was nothing more romantic to their relationship other than them being friends of opposite gender, and the whole thing came off more a combination of awkward teenage hormones and defensiveness in the face of relentless teasing. Worse, [[DatingCatwoman Danny and Valerie]] got real tension and some rather sweet development before [[ShipSinking that ship was sunk]], so it wasn't that the writers didn't know how to write a relationship, they apparently just didn't want to.
* ''WesternAnimation/DragonsRidersOfBerk'': Mala, Queen of the Defenders of the Wing, and [[spoiler: Dagur, Chief of the Berserkers (who had been [[HoYay/DragonsRidersOfBerk blatantly, unambiguously obsessed]] with Hiccup for 7 straight seasons)]], meet for the first time in the show's eighth season. In the B-plot of one episode, they meet, argue, and make peace. The very next time they're seen together, they're engaged. Even in-universe, Hiccup and Astrid are stunned and confused by how... [[SickeninglySweethearts extremely close]] the two got so quickly.
* In the 1990s ''WesternAnimation/FantasticFour'' animated series, Johnny Storm meets ComicBook/{{the Inhuman|s}} Medusa, drools over her for two and a half episodes, finds out she's married, and winds up drooling over her cousin, Crystal, for half of ''one.'' In the end, the Inhumans' city is sealed off from the rest of the world. Suddenly, Crystal, whom he's known all of a few hours, was the love of his life, and he spends every episode after this -- ''[[UpToEleven literally every episode]]'' -- [[{{Wangst}} pining for her]]. (He does get her back in the end, though.) Maybe [[HeroesWantRedHeads heroes really do just love redheads]] that much. The writing team seemingly realized how bad the whole deal was and spoofed it ''hilariously'' in a later episode where Crystal sends out her BigFriendlyDog Lockjaw to try bringing Johnny to a place where they can be reunited. [[RunningGag They spend the whole episode going through several dimensions... and never find that spot]].
* ''WesternAnimation/{{Futurama}}:'' The second direct-to-DVD film "The Beast With A Billion Backs'' has Fry and Colleen, a woman he met on the street one day and had casual sex with, followed by a relationship. Within the space of a few months this relationship is apparently strong enough that Fry is conflicted about whether to move in with her, and so devastated after walking away he feels the need to leave the universe entirely. As opposed to his long-standing attempts to romance Leela, something that gets pointed out at the very end of the film. Making this all the more egregious is that the previous film had the Fry-Leela romance as one of the main plot points, yet it doesn't even get a mention in the supposed follow up until the last two minutes.
* ''WesternAnimation/JusticeLeague Unlimited'':
** [[ComicBook/GreenLantern John Stewart]] and ComicBook/{{Vixen}}. Vixen had previously only made a handful of silent cameo appearances, but without any buildup or reference to it, she and John are already in a serious relationship by her first speaking role. The writers initially paired them up post-time skip just to provide an obstacle for John and Shayera getting back together, but it got pretty difficult for them once Vixen developed as a character and they began to like her (WordOfGod says being voiced by Creator/GinaTorres also helped).
** Poor ComicBook/{{Supergirl}} - [[spoiler:she meets a guy in the future, has a few lines with him, and is suddenly so in love that she abandons all she knows and cares about by [[PutOnABus staying in the far future]].]] [[spoiler:Braniac-5]] is hit pretty hard by this too: he's barely spoken to her, has only known her for a few minutes and suddenly he's agreeing with Green Arrow's suggestion that he's fallen for Supergirl?
* ''WesternAnimation/{{Kaijudo}}'':
** Nadia and Chavez have only two episodes depicting any sort of romance together, but they [[spoiler:share a kiss come the first season finale.]] Bizarrely still, they have no romantic moments after that.
** [[spoiler:Tiera]] and The Choten's relationship seems to exist ''solely'' to [[CruelTwistEnding twist the knife in]] [[IgnoredEnamoredUnderling Alakshmi's]] back. She hadn't even been mentioned by him before this moment, though he could have blocked out her death from his mind.
* ''WesternAnimation/TheLegendOfKorra'': Season 1 was only twelve episodes, with no others originally planned, and had to introduce and conclude a complicated plot about FantasticRacism and a war against {{Well Intentioned Extremist}}s. A romance plot would inevitably have been bereft of necessary screentime to begin with, but then the writers decided to tack on a love ''quadrangle'' seemingly just for the hell of it. The end result is that ''all'' the attractions and romances were rushed, forced, glossed over, [[ShowDontTell told instead of shown]], or quickly buried. The ambiguity of whether Mako and Asami broke up during the season or whether or not Bolin was over Korra didn't help matters. Subverted in Season 2, [[spoiler:where Korra and Mako's personalities clash resulting in Mako breaking up with Korra. And by the end of the season, both accept that a romantic relationship between them won't work and end it for good]]. A Season 4 BreatherEpisode is partially devoted to [[SelfDeprecation mocking how poorly it went]], with Mako's friends and relatives pointing out to him how badly he screwed things up as he tells the sordid story.
* ''WesternAnimation/SamuraiJack'': Jack and Ashi know each other for about a day or two (after Ashi was initially raised from birth to think Jack was the TheAntichrist) and have exactly *two* quick moments of awkward romantic tension before, after a battle, they passionately kiss out of nowhere. The relationship literally goes from "allies with a lot of respect and gratitude for each other" to "passionately in love" with the flip of a switch.
* ''WesternAnimation/SpongebobSquarepants'': At the end of the episode "The Great Snail Race", after Squidward's new snail Snelly chooses to go after Gary (who was in terrible condition and had just recovered from an accident early on) over finishing a snail race, Gary and Snelly fall in love straight out of the blue.
* In season two of ''WesternAnimation/{{Stoked}}'', the first episode involved Reef and Lo pretending to be in a relationship as a subplot in an episode, including pretending to make out. At the end of the episode, the two decided that they enjoyed making out and made out for real, leading to the two of them sucking face uncontrollably in every episode their romance is involved in, [[DerailingLoveInterests derailing]] the previously SpoiledSweet Lo into a SpoiledBrat {{Tsundere}} and the previously chauvinistic Reef into someone who spends hours thinking up lyrics to love songs and poems. The vast majority of fans, unsurprisingly, [[InternetBackdraft hated]] the coupling, especially since the writers had spent most of season one teasing and building up to [[FanPreferredCouple Reef/Fin]], only to strangle Reef and Lo with the red string in the very first episode of Season Two.
* ''WesternAnimation/SuperNoobs'': The romance between Tyler Bowman and Amy Anderson is considered by fans to be underdeveloped and half baked. The aforementioned couple only got a couple of dates with one of them being forced and their relationship was only seldom mentioned in a few episodes. To make matters worse, Amy is regulated to being a DamselInDistress, making her look like a cheap parody of superhero girlfriends like Lois Lane and Mary Jane Watson. Some fans thought that her relationship with Tyler would get more development if she became of the Noobs. What makes this even more baffling is that neither Amy nor her relationship with Tyler is seen or mentioned by the time the season finale episode comes.
* ''WesternAnimation/TotalDrama'':
** On ''World Tour'', [[TroubledButCute Duncan]] and [[PerkyGoth Gwen]]. Yes, this is half of the fanbase's {{O|neTruePairing}}TP, but let's face it--Duncan had ''never'' shown any romantic interest in Gwen before (though she obviously had a thing for him that [[ObliviousToLove he didn't know about]]), and while his relationship with [[WellExcuseMePrincess Courtney]] was certainly [[SlapSlapKiss rocky]], he was always depicted as head-over-heels for her, even taking her back after she was [[CharacterDerailment derailed]] into a VillainSue in season two. In season three, he had ''no'' particular reason to want to break up with her, and when he came back to the show, hadn't seen her ''or'' Gwen in months. And ''less than five minutes'' after coming back, he's making out with Gwen [[YourCheatingHeart behind Courtney's back]], after literally the ''first'' conversation they've had in ten episodes.
** All three become contestants again in the fifth season ''Total Drama All-Stars''. The problems between them resurface, with Gwen being defined solely as a boyfriend stealer, Gwen trying to make things right with Courtney only to accidentally hurt her numerous times, and Duncan still harboring feelings for Courtney. This all culminates in [[spoiler: Gwen dumping Duncan because she feels he's still too interested in Courtney]].
** Subverted with Courtney and Scott. When Courtney is shuffled over to the Villains team, she starts impressing Scott by being her normal, bossy self, saying out of nowhere that, because his dad's in the army and his mom's a waitress, he's basically built to love taking orders and that he loves a bossy lady. This is completely different from his ''Revenge'' portrayal, in which he was a cheating {{Jerkass}}. Then in the episode "Zeke and Ye Shall Find" Scott and Courtney share an AccidentalKiss, to which they start acting as if they'll be together forever. They break up due to a [[AccidentalKiss misunderstanding with Cameron]] only ''hours'' into their relationship, then get back together the episode after, only for the relationship to be possibly [[ShipSinking sunk permanently]] when Courtney's need to win once again proves to be more important to her than her relationships with others and their own feelings.
* ''WesternAnimation/XMenEvolution'': The Lance-Kitty Relationship. The two definitely had the potential to be a good pairing, mostly due to Lance's CharacterDevelopment during the course of the series, but Kitty [[EasilyForgiven forgave him so quickly]] for trying to kill her and her parents in his first appearance - and did so ''before'' his CharacterDevelopment. Said development also appeared to be motivated so he could get together with her, and started from him saving her from a mess he caused.
* ''WesternAnimation/YoungJustice'':
** [[spoiler:Robin and Wonder Girl]] hooking up in the series finale, two characters had never been seen interacting with one another beforehand.
** Miss Martian and Lagoon Boy is at least justified by a TimeSkip, but from the audience's perspective we go from "Miss Martian and Superboy in a successful relationship" (which admittedly had some real groanworthy moments as well) to "Miss Martian locking lips with someone we've never seen before".
** Kid Flash and Artemis were ''supposed'' to be in a love-hate relationship. The show did establish the hate. The two of them were petty and mean-spirited with each other literally from the moment they met. It's on the "love" part of "love-hate" that the show dropped the ball. No indication is ever given why either of these people would find the other likable or attractive (besides the fact that Artemis walks around with a bare mid-riff). They're never shown interacting with each other in a way that portrays romantic interest, and when the latter half of season one tries to convey some romantic interest between them it falls flat.
* ''WesternAnimation/EquestriaGirls'': this is one of the reasons why Flash Sentry is so hated. Twilight, who's had no romantic interest in anyone before, bumps into him several times and starts crushing on him, despite that she knows nothing about him, they have no meaningful interaction and he's of a completely different species. Then when she gets home, she bumps into his pony counterpart and starts crushing on him, despite knowing even less about him and that he's not even the same guy she'd interacted with.
** ''[[WesternAnimation/MyLittlePonyEquestriaGirlsLegendOfEverfree Legend of Everfree]]'': while Flash Sentry is trying to be nice and talk to human Twilight, despite the awkward results, Twilight falls head over heels for Timber Spruce [[LoveAtFirstSight the moment she sees him]]. All of Twilight's friends tease her about how nice a guy Timber is and ignore Flash, Sunset even tells him to get over Twilight. This has angered fans just as much as what happened with Flash, including all of Flash's supporters, because they are ignoring Flash for a new guy instead of working with what they have already established.
** Both of the above are problems Lauren Faust sought to ''[[AvertedTrope avoid]]'' in [[WesternAnimation/MyLittlePonyFriendshipIsMagic the show these two are based on and which she originally designed]]. This trope is just one of the reasons she hated the ''Equestria Girls'' offshoot, as she had intended for the series to avoid [[GirlShowGhetto the "girly" stereotypes of animation aimed at young girls]] that she felt had made past entries in the franchise less than they could have been. Ironically, this was one of the first things Hasbro did with the franchise once she was no longer credited for actively working on it.
