History Main / OneTrueLove

** In particular, in the ''LetsPlay/LifeSMP'', even if he tried to kill Lizzie on at least two occasions in the second season, Joel can always recognize his real-life wife in-game, even if she is possessing another body at the time.
** Their characters also get married in ''LetsPlay/EmpiresSMP'' Season 1, [[WeddingEpisode in an occasion celebrated by the entire server]].

* ''LetsPlay/WitchCraftSMP'': By WordOfGod, Scott and Milo have been referred to as "soulmates". It's PlayedForDrama considering ''how'' [[TheDarkSideWillMakeYouForget downhill]] Scott's mental health has gone in canon after Milo's death [[{{Necromantic}} in an attempt to bring him back]]; a passing comment in the finale [[spoiler:and [[TalkingDownTheSuicidal one]] of the alternate endings]] only further solidify ''[[LivingEmotionalCrutch how]]'' deep the grief goes. However, while this series is technically part of the ''Minecraft'' Multiverse (as above), this trope only holds in the WCSMP continuity for Scott; his characters on other servers have a wide range of other love interests, depending on the SMP.

* ''ComicBook/{{Aquaman}}'' and ComicBook/{{Mera}} are this to the point that most non-comic book fans aren't even aware that Aquaman had other love interests. They were married ''long'' before Lois and Clark and it took the death of their son for there to be any real strain in their relationship. In the New 52, when Aquaman's relationship with Mera ''did'' start breaking down, it turned out to be because [[spoiler:she had been replaced by her evil younger twin sister Hila]].

* {{ComicBook/Jessica Jones}} and {{ComicBook/Luke Cage}} hasn't really had any other love interest than each other since they got married and any issues in their marriage has never involved jealousy or unfaithfullness.
* ''Franchise/{{Batman}}'', despite his numerous relationships in both personas, has only ever loved two women: ComicBook/{{Catwoman}} [[DatingCatwoman and]] ComicBook/TaliaAlGhul. Of those two women, the one that can be described as the love of his life is Catwoman. But because TrueLoveIsBoring, they have never managed to settle down in a lasting relationship with each other long enough to cement them as this in the eyes of the general public, though this has been explored in WhatIf scenarios. In adaptations where Bruce does manage to settle down, it's usually with Selina.

* [[Franchise/GreenLantern Hal Jordan]] and Carol Ferris are living proof that just because you're this, it doesn't mean your [[LovedINotHonorMore relationship]] is [[RelationshipRevolvingDoor stable]]; while Hal admits the only woman he wants to settle down with is Carol, it's not enough to keep them from constantly breaking and making up. Though the epilogue of ''ComicBook/WrathOfTheFirstLantern'' does reveal they ''will'' get their HappilyEverAfter one day.

* In a case of {{Main/Word of God}}, {{Creator/James Tynion IV}} said in an interview for {{ComicBook/Death of Wolverine}} Legacy, that {{ComicBook/Mystique}} has only ever loved one other person and that was her partner, Irene Adler aka Destiny. Her death drove Mystique insane and she has expressed her willingness to do anything in order to get Destiny back several times.

* [[ComicBook/{{Cyclops}} Scott Summers]] and ComicBook/JeanGrey are this to one another -- while Scott married Maddy Pryor (Jean's literal clone, not that anyone realised), and had a long-term relationship with Emma Frost, he was always pining after Jean (something both women were acutely aware of). Likewise, while Jean's flirted with Wolverine a few times, she's always defaulted back to Scott. As teen Hank explains to Bloodstorm (a teenage vampire alternate Storm), her crush on Scott is as doomed as his was on Jean, because Scott and Jean always end up back together -- even after the two spent ages trying to avoid the matter to try and avoid their perceived BadFuture, it happened.
* For ''Franchise/SpiderMan'', it's ComicBook/MaryJaneWatson, a fact that writers and editors have struggled with, given that she's both good for Peter ''and'' popular with the audience, which led to their marriage in the regular continuity after vocal public demand. The issue? See: The TrueLoveIsBoring caveat, one of the things that led to the much-reviled ''ComicBook/OneMoreDay'' storyline that retconned their marriage out of existence. The fact that Aunt May wanted to set her up with Peter, and that she and Peter have a great deal in common (being both poor kids from Queens who wanted to make it big), and that she spent the longest time married to Peter in the regular continuity and appears in most adaptations, made her for most of Spider-Man's history. The only love interest Peter Parker ever came to loving as much as he did Mary Jane was his FirstLove, Gwen Stacy (whose death, incidentally, was what pushed Peter and Mary Jane together in their grief).
* {{Franchise/Superman}}: Clark Kent and [[Characters/SupermanLoisLane Lois Lane]]. Everyone and their dog knows that these two are made for each other. Evidence: every form of media they've ever appeared in. There's not a single adaptation where they don't end up together -- and if Clark ends up with anyone else, it's ''after'' Lois' death. (One exception: In the New 52 they were just work collegues, and Clark eventually started dating Wonder Woman. And then ''Rebirth'' rendered that whole thing CanonDiscontinuity and retconned back in that he'd been married to Lois the ''entire time''.)
* [[ComicBook/RobinSeries Tim Drake]] and [[ComicBook/Batgirl2009 Stephanie Brown]]. They've been a mostly solid OfficialCouple after they got together and only really broke up because Stephanie died ([[DeathIsCheap or faked her death]], [[{{Retcon}} so to speak]]). They got back together in ''ComicBook/{{Convergence}}'', as did their New 52 counterparts, and have barley shown any interest in anyone else since.
* [[ComicBook/TheFlash Wally West]] and Linda Park may rival Lois and Clark in this regard. They've literally come back from the dead for each other through ThePowerOfLove, and their love was so strong that when Neron (DC's stand-in for {{Satan}}) took it, [[TooSpicyForYogSothoth it almost killed him]].
* Franchise/WonderWoman: Diana and ComicBook/SteveTrevor have been each other's love interests since the Golden Age of Comics. One of the reasons for Diana’s lack of romance Post-Crisis is because Steve was demoted from being her love interest and paired off with Etta Candy instead. Any and all attempts to pair Diana with other men failed because they simply lacked the chemistry Steve and Diana had, which eventually led to Steve being promoted back to being Diana’s love interest in ComicBook/DCRebirth.

* ''Series/GoodOmens2019'': Platonic example [[spoiler:until season 2]]
** Angel Aziraphale and demon Crowley for each other.
** [[spoiler:In season 2, Crowley finally confesses his undying love for Aziraphale and kisses him]].

It's PlayedForDrama considering ''how'' [[TheDarkSideWillMakeYouForget downhill]] Scott's mental health has gone in canon after Milo's death [[{{Necromantic}} in an attempt to bring him back]]; a passing comment in the finale [[spoiler:and [[TalkingDownTheSuicidal one]] of the alternate endings]] only further solidify ''[[LivingEmotionalCrutch how]]'' deep the grief goes. However, while this series is technically part of the ''Minecraft'' Multiverse (as above), this trope only holds in the WCSMP continuity for Scott.

* In the ''Minecraft'' Multiverse, Joel [=SmallishBeans=] and Lizzie [=LDShadowLady=] the content creators are HappilyMarried in real life, and the series they're in frequently establish their roleplay characters' love to transcend the servers they're on, [[RealIfeRelative as a reflection of their content creator counterparts' dynamic]].

* ''Series/{{Yellowstone}}'': Kayce and Monica Dutton are VERY much this. From the beginning of the series, it’s obvious that they are deeply in love. Even when they argue, it’s clear that their love for one another is at the forefront and no matter what happens, it’s the two of them, that’s it. Dialogue implies it was true from the very beginning.
-->'''Kayce:''' I’m trying to remember what I was wearing when I met you.\\
'''Monica:''' All I remember is, you weren’t wearing it for long.

It's PlayedForDrama considering ''how'' [[TheDarkSideWillMakeYouForget downhill]] Scott's mental health has gone in canon after Milo's death [[{{Necroromantic}} in an attempt to bring him back]]; a passing comment in the finale [[spoiler:and [[TalkingDownTheSuicidal one]] of the alternate endings]] only further solidify ''[[LivingEmotionalCrutch how]]'' deep the grief goes.

The main difference between a standard OfficialCouple and a OneTrueLove is in how each partner views the other. While an OfficialCouple simply needs to be a canon pairing between two characters, a OneTrueLove also requires a canon couple to view each other as their be-all, end-all soulmate with no romantic interest in anyone else once the pair gets together. This is comparable to the difference between "daisuki" and "aishiteru", both terms meaning "I love you" in Japanese. "Daisuki" is a casual term that couples typically use whether they are dating or married. It can be heard often between partners in public, and it can also double for loving a thing (ex. "I love pizza" or "I love watching basketball"). "Aishiteru", on the other hand, is a term reserved only for couples that view themselves as soulmates. Those who say "aishiteru" would do anything necessary to stay by their partner's side and view their partner as their OneTrueLove. It's a serious term, and you'd seldom, ''if ever'', hear it in public explicitly for this reason.

* ''Literature/GrandmasterOfDemonicCultivationMoDaoZuShi'':Mo Xiang Tong Xiu revealed she tried writing many different love interests for Wei Wuxian but nobody clicked until she ultimately concluded that Lan Wangji, the very first love interest she wrote, was perfect for him. The story went out of its way to reinforce this stance: from their OppositesAttract dynamic to Wei Wuxian pulling Lan Wangji's forehead ribbon (that only family members or spouse can touch), to creating a LoveTheme named after their [[PortmanteauCoupleName courtesy names]]. It's also clear that both are attracted to each other at first sight, have never been romantically interested in anyone else and even being dead for 13 years and being transmigrated in a different body will not stop Lan Wangji from loving Wei Wuxian.

* ''Franchise/IndianaJones'': Throughout the films, Indiana has had a few flames and even admitted to having others, but the one whom he has continuously cared for the most is Marion Ravenwood. Their relationship, however, was never easy, as the two do spend much of their time bickering. Indy and Marion had a fling ten years prior to ''[[Film/RaidersOfTheLostArk Raiders]]'', where Marion tells him that she loved him only for him to leave her since their tryst destroyed his friendship with her father. Marion is initially angry at seeing Indy again, but throughout their adventure their relationship rekindles, and the film ends where she invites him to get a drink. Unfortunately, Indy's commitment to his archeology work & constant adventuring ended their relationship again, but Marion hides the fact that [[spoiler: she was pregnant with their son, Mutt]]. The two reunite a second time in ''[[Film/IndianaJonesAndTheKingdomOfTheCrystalSkull Crystal Skull]]'' where they realize that they still care deeply for each other [[spoiler: and the film ends with them finally marrying, with Indy happy to be with the woman he loves and happy to have a son]]. Unfortunately, by ''[[Film/IndianaJonesAndTheDialOfDestiny Dial of Destiny]]'', [[spoiler: Mutt has died while serving in the Vietnam War, which [[GriefInducedSplit made their marriage fall apart and for Marion to file for divorce]], which made Indy miserable. In spite of everything, it's apparent that Indy still loves Marion and continues to wear his wedding ring throughout his adventure with Helena. When he finally returns to his apartment in New York at the end of the film, Helena invites Marion over to bring groceries. Indy is surprised to see her, but the two realize that they still love each other, and are back together again]].

* In ''Fanfic/OneDayAtATimeFanfic'' and its sequel ''Fanfic/TheSuperheroGame'', Jason Todd has only ever really loved three women in his life. However, he admits the only one that can really be described as the love of his life is Donna Troy. [[spoiler:When Donna comes back in time like him, she admits she feels the same way about him, and the two lose no time in restarting their relationship]].

* {{Franchise/Superman}}: Clark Kent and [[Characters/SupermanLoisLane Lois Lane]]. Everyone and their dog knows that these two are made for each other. Evidence: every form of media they've ever appeared in. There's not a single adaptation where they don't end up together -- and if Clark ends up with anyone else, it's ''after'' Lois' death.

** On the other hand, "The One That Might Have Been" reveals that, even if everything was different, Monica and Chandler would still end up together. Also, Ross would still end up in a WouldTheyOrWontThey with Rachel (although his crush on her does precede the point of divergence).

* Parodied in an episode of ''Series/{{Friends}}'': Phoebe asks Chandler if he believes in soulmates. He doesn't, he believes in falling in love, but not that there's one person who's perfect for you. She says "Good, because I just met Monica's!" The rest of the episode is him feeling increasingly threatened by this guy until Monica explains she doesn't believe in One True Love, either.
-->'''Monica''': I don't think that you and I were destined to end up together. I think that we fell in love and work hard at our relationship. Some days we work ''really'' hard.

* Deconstructed in a ''Website/WhatIf'' [[https://what-if.xkcd.com/9/ entry]]. While Munroe doesn't attack the idea of someone who is perfect for you, he ''does'' address the corollary -- that you'll be miserable with anyone else -- and points out how that condemns the ''vast'' majority of humans to a loveless existence.

* Deconstructed in a Webcomic/{{XKCD}} [[https://what-if.xkcd.com/9/ What If?]]. While Munroe doesn't attack the idea of someone who is perfect for you, he ''does'' address the corollary -- that you'll be miserable with anyone else -- and points out how that condemns the ''vast'' majority of humans to a loveless existence.

* ''WesternAnimation/{{Shrek}}'': Shrek and Princess Fiona. The spell cast on Fiona to eventually break her curse is supposed to allow her to meet her true love (who is supposed to rescue her from the dragon guarding her while she's in the highest room in the tallest tower), with TrueLovesKiss sealing the deal. The problem is that no one really expected Fiona's true love to be an ogre (least of all Fiona herself), so it takes time for them to really acknowledge they're this. It's also something of a deconstruction, in that while Shrek and Fiona are soulmates, they aren't actually in love with each other when they first meet, instead falling in love while they're traveling to Duloc in order to deliver Fiona to Lord Farquaad to be his bride. As all but stated by ''WesternAnimation/ShrekForeverAfter'', even if Shrek had kissed Fiona when they first met, it wouldn't have broken the curse because they weren't actually in love yet.

* Quite literal in the Creator/{{Netflix}} series ''The One''. Rebecca Webb and her business partner James have developed a dating service that finds your "match", who is pheromone DNA matched to be the best person for you. From what is seen in the show, it works and changes dating as we know it.
