In some stories, a FlashSideways - or even outright TimeTravel - can be caused by ThePowerOfLove. Not just motivated by it. CAUSED by it.

So strong is their love that no boundaries are capable of keeping these lovers apart. Not even the boundaries of space, time, fourdimensional spacetime, or even [[TheWallAroundTheWorld The Barrier]] between [[AlternateUniverse different universes]].

Not limited to TimeTravel and timelines, the trope also applies to certain cases of [[ReincarnationRomance targeted reincarnation]], long-range telepathy et cetera.

Contrast StarCrossedLovers. See also TimeTravelRomance.

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* The first ''{{Inuyasha}}'' movie had the subtitle ''Toki wo Koeru Omoi'' / ''Affections Touching Across Time'', which referred to a scene where Kagome (in the present) and Inuyasha (in the past) both touch the goshinboku tree and then can communicate telepathically. (They did this because the Bone-Eaters' Well was out of order.)
** The ending of the series proper features [[spoiler:Kagome's love for Inuyasha allowing her to travel to the past through what's left of the Bone-Eaters' Well, after it had been erased by Naraku's wish and/or the Shikon Jewel itself.]]
* ''GurrenLagann'': By the second part of the series, [[spoiler:love renders you capable of teleportation, and it's weaponised so Simon can [[GetAholdOfYourselfMan Bright Slap]] Rossiu out of commiting suicide. Although that worked because of [[ShrinkingViolet Kinon's]] romantic love for Rossiu ''and'' Simon both supporting her love and still considering Rossiu enough of a friend to go InterruptedSuicide on him even after he condemned him to death]]. Love is, of course, far from the only thing in the setting that transcends spacetime, and not to mention there are ''many'' kinds of love aside of romance.
** Also, [[spoiler: Nia should have vanished when the Anti-Spiral was destroyed. [[PluckyGirl She]] managed to hold on for ''at least'' a week after that, because of her love for Simon, and only faded away after they got married and she gave him a LastKiss.]]
* In ''VoicesOfADistantStar'', junior-high sweethearts Mikako and Noboru are separated when Mikako is selected as a HumongousMecha pilot and sent with the fleet into space. As the fleet does not have FTL communications technology, the only means of contact the two have is email, with increasingly long delays in transmission - first six months, then a year, until finally Mikako ends up eight and a half lightyears from Earth. The anime does some deconstructing as both Mikako and Noboru struggle to cope with the separation - Noboru at one point even making up his mind to give up on Mikako, saying that "a distance that takes eight years at the speed of light is no different than saying 'forever'," - but ultimately plays the trope straight in its final scenes.
-->''"I am here."''
* In the ''The Book of Bantorra'', Colio Tonies falls in love with the centuries-dead "Ever-Laughing Witch" Shiron Byacornaise when he reads her "book" (in this series, a stone tablet in which the memories of a person's lifetime crystallize upon their death) and finds that she had [[{{Seers}} visions of him]] loving her in the future.
* An episode of ''{{Anime/Pokemon}}'' had May and Meowth hurled back in time for no discernible reason but to get a couple to hook up. This was before [[TimeMaster Dialga]] was introduced to the canon.
* Noelle and Yusuke from ''Anime/{{TenshiniNarumon}}''- [[spoiler: in the final episode]] their love for each other makes them able to [[spoiler: touch each other again, after Noelle became full angel]]. Also, strongly hinted to be basis of [[spoiler: Raphael and Mikael's relationship]]

[[folder:Comics]]
* One old storyline in ''Comicbook/{{X-Men}}'' is that Professor X had a long distance relationship with the empress of another galaxy. Having never even visited each other's galaxies before, their minds nontheless touched telepathically by the virtue of being soulmates.
* [[TheGoldenAgeOfComicBooks Golden Age]] {{Hawkman}} and Hawkgirl.
* The various [[TheFlash Flashes]] use their loved ones as an emotional tether to avoid bouncing uncontrollably through time or being absorbed by the Speed Force their powers draw upon.
* In ''ComicBook/CityOfDreams'', the prince and the queens appear to be visitors in the waking world, coming there only for the protagonist.
* In ''ScottPilgrim'', when [[spoiler: Gideon KILLS Scott on volume 6]] we see more than half a page full with reaction shots... including [[spoiler: Kim Pine, who isn't even remotely near the scene, but still felt it.]] It's only a panel, casually sneaked in, but it's colored darker than the rest, drawing attention to itself.
[[/folder]]

[[folder:Fanfiction]]
* An interesting case happens in the Glee fanfic [[http://www.fanfiction.net/s/6995918/1/but-with-a-whimper But A Whimper]]. The premises is that everyone is born with their soulmates name on their hand. Soul mates can be born in a different time though. And then the story averts this trope. [[spoiler: Quinn's soul mate ends up being a singer from somewhere around the 1920s. He obviously died and she has to deal with a heart that's broken to smithereens.]]
* In the [[Fanfic/BloodBondBloodOmenSeries Blood Bond Blood Omen Series]] of fanfics for KimPossible, Kim and Ron have been kept apart in all their previous incarnations by a curse. When they finally break it, they achieve this trope.
* The ''Film/StarTrek'' fanfic ''[[https://www.fanfiction.net/s/9795158/1/Written-in-the-Stars Written in the Stars]]'' takes this trope and runs away with it. Spock and Fem!Kirk end up together in ''four different realities'', '''no matter what happens'''.

[[folder:Film]]
* Played straight in ''JustLikeHeaven''. The main character David sees a ghost Elizabeth, who believes she still lives in her old apartment. Over the course of the movie, they genuinely start to love each other, when he finds out [[spoiler:Elizabeth is in a coma]]. He races to prevent [[spoiler:her death]], and succeeds. Once this happens, their love transcends [[spoiler:her re-entering her body, forgetting him completely.]]
** On top of that, it's revealed that [[spoiler:on the night Elizabeth was in the car accident that put her in the coma, she and David had been on their way to have a blind date with each other, hinting that the two were somehow always connected.]]
* In "RunLolaRun", love alone appears to allows the protagonist to reload the day and try again.
* Played straight in ''Film/DejaVu''- Doug regularly gets feelings of "deja vu" where he feels as though he has experienced similar events before such as when he is in the time machine or in the car listening to the radio. Unbeknownst to him these events actually happened in previously altered timelines to alternate versions of himself. It can be imagined that this is due to the power of his love for Claire or fate dictating that they be together.
--> '''Claire''' What if you had to tell someone the most important thing in the world, but you knew they'd never believe you?
--> '''Doug:''' I'd try.
* In ''Film/SlidingDoors'', the main character finds her true love in one of the timelines. [[spoiler: She eventually finds him in the other timeline as well, because she recognizes him from the Deja Vu kind of FlashSideways she gets from loving him in the first timeline.]]
* In the movie MadeInHeaven, when Annie incarnates for the first time (leaving Heaven in the process), Elmo reincarnates to be with her even though Emmett (a stand-in for God) warns him that they only have 30 years to meet. The searching is the basis for the entire movie. Eventually, [[spoiler:when they see each other on the street, they remember their past in Heaven, including their love. This becomes a CrowningMomentOfHeartwarming ending]].
* There's ''TheFountain'', where a couple are seemingly re-incarnated and fall in love again and again.
* ''DeadAgain'', where The Boy and The Girl are reincarnations of a previous pair of lovers. [[spoiler:Except in their previous lives The Boy was The Girl and The Girl was The Boy.]]
* In ''Film/SomewhereInTime'', Richard wills himself to teleport backwards in time so he can be with his true love Elise. [[spoiler: Then, [[StarCrossedLovers they're separated forever]]. And ''then'', [[TogetherInDeath they're reunited when he ACTUALLY dies]].]]
* The film ''For All Time'' - based off the classic ''Series/TwilightZone'' episode "A Stop At Willoughby" - heavily implies that this is what keeps pulling the protagonist back into the past. (Incidentally, the lovers are played by [[Series/{{NCIS}} Mark Harmon]] and [[MaryMcDonnell Mary]] [[Series/BattlestarGalacticaReimagined [=McDonnell=]]].)
* In ''Happy Accidents'', time travel itself is done via technology, but the protagonist says that the past can only be changed through an extreme amount of emotional energy. This leads him to think that he can save the life of a woman whose photograph he fell in love with in the future. [[spoiler: It works.]]
* At the end of ''[[Literature/{{Nightwatch}} Daywatch]]'', [[spoiler: Anton]] uses the chalk of fate to alter something he did [[spoiler: twelve years prior.]] As a result he never met or fell in love with[[spoiler: Sveta.]] As he passes her on a walk through the park, Zavulon and Gesser argue over whether or not he will recognize her. [[spoiler: He does]]
* In ''Film/StarTrekInsurrection'', Picard's girlfriend can slow down time, but only when doing so makes it really really romantic.
* Sadly subverted in JackieChan's ''TheMyth''. Jack is not really Meng Yi, and the princess who had been waiting for Meng Yi, floats away from him to die in the tomb.
* The premise of ''Film/TheLakeHouse''.
[[/folder]]

[[folder:Literature]]
* Near the end of Creator/EEDocSmith's last ''Literature/{{Lensman}}'' novel ''Children of the Lens'', Kimball Kinnison is thrown outside the space-time continuum. His wife Clarrissa, his children and Mentor of Arisia use the PowerOfLove to find him and bring him back.
* ''TheTimeTravelersWife''
* Played with in the short story "Bad Timing". A man from the future reads a story in an old magazine about a woman who falls in love with a time traveler, who traveled to her time because he read a story she wrote about him. The man in the story is obviously him, and he sees a picture of the author and falls in love, so he steals an experimental time machine and goes to find her in the past. However, he doesn't have all of the manual for the time machine, and instead of creating the expected StableTimeLoop, he keeps arriving at all the wrong parts of her life--like when she's five years old... or when she's about to die... or just after she's married someone else...
* In the ''WheelOfTime'', Rand is the reincarnation of Lews Therin Telamon. One of his love interests, Elayne, is heavily implied to be the reincarnation of Illena, Lews Therin's wife. Birgitte and Gaidal Cain also meet and fall in love every time they are reincarnated.
* In the ''Literature/DragonridersOfPern'' novel ''Dragonquest'', Brekke's love for F'nor is apparently enough to telepathically reach out to the Red Star and cause Canth to teleport them home, despite being unconscious at the time. Although there is occasional mention of "empathy," no human character in the series had ever evidenced the ability to telepathically communicate across interplanetary distances before (or after).
* MercedesLackey's ''[[Literature/HeraldsOfValdemar By the Sword]]'' plays with the trope a bit with Kerowyn and Eldan - the beginning of the last third of the book shows that Kero has had recurring dreams about Eldan over the ten years since they met, fell in love, and parted. Only when they are reunited some chapters later does Kero discover that the dreams were not ''just'' dreams: the two of them were [[TalkingInYourDreams communicating telepathically]] the whole time, from completely different countries, a fact that gives her a considerable shock when she realizes it. (Eldan, who'd already figured it out, is rather sheepish.)
* In ''Beastly'', [[spoiler:when Kyle looks in the magic mirror and sees Lindsy being abducted, he can somehow hear her her screaming for him, even though the mirror doesn't provide sound for what it shows. It's chalked up to Lindsy and Kyle sharing a connection like JaneEyre and Mr. Rochester, and it's revealed that Lindsy had been trying to invoke that connection to find him as well.]]
* In Caroline B. Cooney's Time Travelers Quartet, members of the Lockwood and Stratton families keep being pulled across hundreds of years to each other's sides, the implication being that they're meant to be together.
[[/folder]]

[[folder:LiveActionTV]]
* ''Series/{{Lost}}'': Desmond has a history of mental time-travel in which his girlfriend Penny serves as his [[TheConstant Constant]] (also TropeNamer): his first time-traveling experience is at least partially triggered by him proclaiming his life to her, his second one is stopped when he makes contact with her in both time periods.
** And then later the FlashSideways allows all principal characters to reunite with their love interest regardless of the mistakes they made in the original timeline.
* In ''Series/DoctorWho'' Series 5, Amy's love brings back, first Rory, then her Parents, and finally the Doctor himself from nonexistence.
** Between Rory's death and his revival, there was also the fact that Amy's love helped her remember Rory on some subconscious level, even though he'd been completely erased from existence and thus have nothing left ''to be'' remembered.
** Furthermore, the romance between the Doctor and River Song, besides the two of them having perhaps the most ''convoluted'' romance in existence. How convoluted? [[spoiler: He was present at her birth, he was almost romantically engaged with her mum, Amy, she was raised to kill him, their time lines are roughly back-to-front, so his first meeting was her last, etc...]] It seems to be working out pretty well, all things considered.
* ''LoisAndClark'' had an episode where it was revealed they were lovers in past lives and that Tempus's lives in those times hated Clark as much as the mainstream Tempus hates Clark/Superman.
** [[WhatCouldHaveBeen Originally]], LexLuthor would be that episode's villain, but the actor who portrayed him in that series wasn't available when they filmed the episode.
* ''Series/BabylonFive'': The canon novel ''To Dream in the City of Sorrows'' implies that Catherine Sakai, pulled through the time rift, finds Valen (aka her love [[spoiler:Jeffrey Sinclair]]) in the past, and that the power of their love had something to do with it.
* ''{{Fringe}}'' has Peter and Olivia. They cross universes, rewrite time lines and change the future.
** And now as of episode 4x20, we have [[spoiler: Lincoln Lee crossing universes ''permanently'' to be with [[DoppelgangerReplacementLoveInterest Fauxlivia]].]] Fringe runs on this trope.
[[/folder]]

[[folder:Music Videos]]
* The ending of [[Music/{{aha}} Take on Me]], where the guy from the comic world apparently dies in a HeroicSacrifice to save the main girl but shows up alive in the real world. [[spoiler: [[TearJerker Cruelly subverted]] at the start of the video for "The Sun always shines on TV"... [[StarCrossedLovers it was only a temporary effect]] so the guy turns back into a drawing and has to leave and [[TheWoobie the poor girl]] [[DidnotGetTheGirl ends up all alone]].]]
[[/folder]]

[[folder:TabletopGames]]
* In ''TabletopGame/{{KULT}}'', passion can be strong enough to make people even return from the dead, and this trope is even less a problem.
[[/folder]]

[[folder:Theatre]]
* The end of ''Theatre/{{Brigadoon}}.'' Tommy turned down joining Brigadoon, but magically gets let in anyway 4 months later.
[[/folder]]

[[folder:VideoGames]]
* ''SakuraWars: So Long My Love''. A flashback reveals that 500 years ago, a previous incarnation of the main character Shinjirou battled the Demon Lord OdaNobunaga along with several comrades, and one mysterious foreign nun. They fall in love, but she has to perform a HeroicSacrifice in order to [[SealedEvilInACan seal the Demon Lord]]. Before she dies, she assures him that their souls will find their way together again someday. [[SchrodingersGun Whichever of the main girls you choose at the end of the game turns out to be a reincarnation of said nun]].
* In ''KingdomHearts'', [[Disney/BeautyAndTheBeast Beast]] was able to travel to Hollow Bastion to save Belle by sheer willpower.
* In FireEmblemAwakening, this is played straight if [[spoiler: you choose the Sacrifice Ending (having the Avatar kill Grima knowing that s/he will be erased from existence if s/he does so.) with a married Avatar. Sh/he ''is'' erased as the price for vanishing Grima forever, but ultimately returns to his/her friends and spouse/children.]] Though if you include ''[[TheFourLoves other]]'' [[TheFourLoves kinds of love]] aside of romance, like [[TrueCompanions friendship]] or [[PatrioticFervor love for the continents/countries]] or [[spoiler: familiar love (Mom or Dad Avatar to any of his/her possible children)]], then it's '''always''' played straight.
[[/folder]]

[[folder:VisualNovels]]
* ''FateStayNight'' gives us Saber and Shirou (at least in the [[UpdatedRerelease Realta Nua]] version), who manage to fullfil the StarCrossedLovers prophecy of Merlin (Shirou must forever search for Saber, and Saber must forever wait for Shirou) and reunite in Avalon.
* ''VisualNovel/NineHoursNinePersonsNineDoors'' has this as its' main premise: [[spoiler:Morphogenetic fields work across large distances and even through time between two persons who are close to each other (not necessarily in a romantic way), allowing Akane to contact Junpei 9 years in the future.]]
* This is revealed to be the cause of much of the plot of ''MuvLuvAlternative''. [[spoiler: Sumika's desire to see Takeru again, combined with the dimensional distortions caused by G-Bombs, is what leads to him being drawn to her universe.]]
[[/folder]]

[[folder:WebComics]]
* In ''TheDreamer'', Alan and Beatrice have a rather complicated relationship, to say the least. Bea can only see Alan in her dreams.
* In ''Webcomic/GunnerkriggCourt'', it turns out that [[spoiler:Parley]]'s powers work like this.
