->'''Kagura''': ''You promised you'd marry me!''\\
'''Kyo''': ''Because you threatened me!''
-->--''FruitsBasket''

A common staple of stories featuring ChildhoodFriends is the ChildhoodMarriagePromise. Years ago, when two of the main characters were small children, they promised to marry each other when they grew up. Now they're in HighSchool or university, and SheIsAllGrownUp. Sometimes, the couple fall in love for real and [[VictoriousChildhoodFriend they finally fulfill that promise.]] Other times, one of them is the UnluckyChildhoodFriend whose heart gets broken, since the FirstGirlWins BecauseDestinySaysSo.

A slight variation, one that usually comes up in Fantasy or Sci-Fi anime, is where the boy promises to always protect the girl (which, in the traditional sense of marriage, is pretty much the same thing). See BodyguardCrush. See also DeclarationOfProtection, which can be read both ways. Often arises in a ForgottenFirstMeeting scenario.

The ChildhoodMarriagePromise is often made in the shadow of TheWorldTree.

Compare PuppyLove, which may lead to this. When it's the parents who make such an agreement, you have the decidedly-less-heartwarming ArrangedMarriage. When two adults make such a deferred arrangement in order to avoid being single in old age, it's a FallbackMarriagePact.

!!Examples:

[[foldercontrol]]

[[folder:{{Anime}} and {{Manga}}]]

* In ''LoveHina'', Keitaro is determined to find the girl he pledged to marry as a child, although he can't for his life remember who she is. ([[spoiler:All evidence points to either Naru or Mutsumi -- or both. Mutsumi claims it was Naru.]])
** The end of the manga reveals that as a child, [[spoiler:he wanted to marry Mutsumi at first, but she made him promise Naru that he'd marry her -- because Mutsumi knew Naru was also in love with him, and she wanted them both to be happy. Since the entire manga plays on Urashima Taro, it was ultimately Mutsumi, the fated girl, who said "ScrewDestiny" and gave away the guy as far back as when they were preschoolers, and the whole manga is just the fallout of that choice. Given that his aunt beats him to "Toudai", ScrewDestiny is very much in play throughout the manga.]]
** This is also played with at the end of the manga when he asks his grandmother who his promise was with and she yells out (while boarding a helicopter) that the girl he promised has been with him 'all along' prompting EVERY GIRL AT HINATA SOU to proclaim that she's the one!
* Hazumu and Tomari in ''KashimashiGirlMeetsGirl'', with the added complication that Hazumu is now a girl. Amusingly, the original promise was Hazumu promising to be Tomari's ''bride'', which received an angry response from Tormari that as a boy, he'd have to be the groom. [[GenderBender Oh, how things can change...]]
* Keiichi and Belldandy in the original OAV animated version of ''Manga/AhMyGoddess''.
* Subverted by James in ''Anime/{{Pokemon}}'', since back then he didn't know Jessiebelle's real personality and once she showed her colors, he didn't want anything to do with her.
* Chihiro and Ritsuko in ''KujibikiUnbalance''. Of course, considering the source, it's an AffectionateParody.
* It eventually turns out that Ranma and Ukyo in ''RanmaOneHalf'' have one of these, made when Ukyo tried to make some of her family's okonomiyaki sauce while they were kids. She promised to let Ranma taste it when it finished aging after ten years, if Ranma would vow to "look after her for the rest of her life" if it turned out good. Of course, at the time, Ranma didn't know either that Ukyo was actually a girl or what he was promising, and through a lot of confusion the promise ends up being broken when it comes up again. Unfortunately for Ranma, Genma and Ukyo's father had brokered an ArrangedMarriage shortly after he and Ukyo made their ChildhoodMarriagePromise (which Genma tried to run out on), meaning Ukyo still persists that she has a claim to his hand. [[CaptainObvious Because she does]]. This is further complicated by the fact that Genma has promised Ranma's hand in marriage to several girls (and in the anime to a couple others as well) because he's a jerk.
* The ChildhoodMarriagePromise is a touching central theme in ''Manga/AiYoriAoshi'', as Aoi and Kaoru were promised to marry due to their families... but the promise was broken due to Kaoru walking out on his [[AbusiveParents horribly abusive grandfather]]. However, when he meets a grown-up Aoi who still likes him, [[ChildhoodFriendRomance Kaoru falls for her all over again.]]
* [[KissingCousins The cousins]] Li Shaoran and Li Meiling in the anime version of ''Manga/CardCaptorSakura''. [[spoiler: They don't go through it, since the promise was that Meiling would be Shaoran's bride until he found someone he loved more... thus [[UnluckyChildhoodFriend Meiling]] steps aside willingly when she realizes that he's fallen in love with their common friend Sakura. The scene where Meiling breaks down crying on the lap of Sakura's own UnluckyChildhoodFriend, Tomoyo, is ''[[TearJerker heartbreaking]]'']].
* Subverted in ''FruitsBasket'', where Kyou's promise to Kagura was extracted by her threatening him with a knife (or a large rock in the anime).
** A variant happens between Kyo and Tohru, though he makes the promise through Tohru's ''mother'' Kyoko, whom he had an InterGenerationalFriendship deal with. When Tohru gets lost on her way home from school, Kyo makes "a man's promise" to find Kyoko's daughter and protect her. When Tohru is brought home by someone else, Kyoko teasingly tells him that she'll put the promise "on his tab". At the end of the series, when Kyo and Tohru are in their late teens, they agree to basically go live together after graduation (and eventually do get married); Kyo thinks back to his promise, and relates his vow to protect Tohru to him essentially being her husband - that he will keep his promise for the rest of his life.
%%* Subverted in ''[[RevolutionaryGirlUtena Shoujo Kakumei Utena]]'', in which Utena starts out the series looking for the prince on a white horse who rescued her as a child and gave her his ring, only to find... [[MindScrew well, it's kind of complicated]].
* The whole point Milk is obsessed with--and creepily stalking--Reiner in ''[[TheLegendOfTheLegendaryHeroes The Legend of the Legendary Heroes]]''
* In the anime version of ''Manga/InuYasha'', Koga lightheartedly promises to marry wolf-girl (and granddaughter of a very powerful wolf youkai [[TheObiWan whom he quite respects]]) Ayame, then still a young child, after [[RescueRomance he saves her from being killed]]. She reappears [[SheIsAllGrownUp all grown-up]] and demands he fulfill his promise, but he's already in a {{Love Triangle}} with Kagome and Inu Yasha. Even worse, the poor guy doesn't remember a thing about it, and Ayame not only is hurt and angry as Hell with quite the reason, but ''Kagome'' is pissed at him too because she doesn't want Ayame to be hurt. By the end of the series, [[spoiler:Koga finally fulfills his promise]].
* A somewhat similar variation shows up in KenichiTheMightiestDisciple. Years ago Sakaki promised the young daughter of a friend he would marry her (he was drunk at the time). But now Jenny Grey wants to hold him to that promise.
* In ''{{Dragonball}}'', Chichi and Goku first meet as children, and Goku promises to marry her, thinking marriage is a kind of food. He says so when an angry and [[SheIsAllGrownUp all grown-up (and very pretty) Chi-Chi]] brings it up in the Tenkaichi Budokai, but Goku keeps his promise anyway and marries her.
* In a bit of a twist, in ''The Five Star Stories'', Lachesis promises to marry Ladios/Amaterasu when she's 10 or so... and he's over 100. But then, he's a god, she's an ArtificialHuman (and possibly an incarnation of a goddess) & they're both immortal, so it's not nearly as {{Squick}}y as it sounds.
* Played with in ''Manga/FullmetalAlchemist'', when Alphonse asks Edward if he remembers the time when they fought over who would marry Winry. Al won the fight but she rejected both of them saying "I don't like guys who are shorter than me". Incidentally, by the end of the series Ed is now (slightly) taller than Winry.
* Sanpeita, the protagonist of ''KemekoDeluxe'' made one ten years ago with a girl he knew. Ten years later, a girl who looks strangely like her in some sort of PoweredArmor returns to protect him...and also claims to be his wife.
* The promise is made between Ryouta and Chika when they are children in ''Kyou no Go no Ni''. A bit unique in that they're ''still'' kids by the time of the anime, just slightly older, and it's actually the male half of the pair who remembers it.
* Played with in ''{{Futakoi}}'': Ichijou twin sisters ''(together)'' expressed their intent to marry Nozomu when they all will grow up. When they ''did'' grew up and met again, there were definite affections from all three sides, all right. [[spoiler: Each (separately) reminded him about this proposal and tried to downplay her own role (claiming it was half- friendly competition, half- cooperation with other sister)... [[NoExceptYes only to set her sibling forward, while both still paid more attention to their "non-fiance" than to everyone else]].]] [[ThemedHarem It's Futakoi]], though, so a MindScrew was really to be expected.
* In ''CodeGeass'', Nunnally and Euphemia have a good old laugh when they remember the times they fought as children over who would get to marry Lelouch. Considering they are, respectively, his sister and his half-sister, and further considering he has a metric ton of SubText with Nunnally (lampshaded more than once) and actually calls Euphemia his 'first love', it's probably for the best that they never mention this conversation to him.
* In ''HoneyCrush'', Kyouko and Madoka shared one when they were younger. They're both female but Madoka thought that Kyouko was a [[UnsettlingGenderReveal boy at the time]].
* Rumiko Takahashi's one shot ''The Laughing Target'' has a ChildhoodMarriagePromise that jump starts the plot. The story goes beyond {{Deconstruction}} and outright ''attacks'' this trope; one partner's determination to uphold the promise is shown to be creepy and unhealthy [[spoiler: and that's on top of her being a {{Yandere}} with supernatural powers]], ''not'' cute and romantic.
* [[SubvertedTrope Subverted]] in ''Anime/FullMetalPanicFumoffu''. A LonelyRichKid, in [[{{PrecociousCrush}} his attempt to woo]] Chidori, tells her about a recent tragedy that has [[ButtMonkey shattered his spirit]]. His tale begins as a clichéd romance thwarted by a terrible car accident. Then it turns out that the 'tragedy' is that the girl in question eloped with a boy she met in the accident, and moved to Amsterdam. He still gets postcards.
* Implied, but not directly said in ''GaoGaiGar'', when Hana reminds Mamoru about a promise they made when they were young (''er'') children. Mamoru can only blush in response. Of course, they're [[ToyShip all but dating as it is]].
* Hayate and Athena from Manga/HayateTheCombatButler. They promised to spend the rest of their lives together and even gave each other promise rings. Izumi promised to be his bride as well.
* Referenced in ''Manga/YuYuHakusho''. When Yusuke proposes to Keiko, she looks stunned... until her dad starts laughing and reminiscing about how Yusuke ''always'' tried to make up with her after a fight by asking her to marry him.
* This was the basis of the {{Manhwa}} ''Manhwa/PigBride'', with the added twist that it's based on [[spoiler:a ReincarnationRomance.]]
* Happens between Tagaki and Rei as a pinky swear in ''HighSchoolOfTheDead'' .
* Yuuto of ''OmamoriHimari'' had made the DeclarationOfProtection (or more accurately, I Will Definitely Watch Your Back, as they were planning to be demon hunters, and her spells only go forward) version to Kuesu in his youth while their families worked out a betrothal between them. Then they separate for about a decade. When they next meet, he had completely forgotten her, completely rethought his views on demon hunting, and acquired an UnwantedHarem, most of whom are members of the demon races that they had originally planned to exterminate in their youth (And which Kuesu still wanted to do). It makes for a rather bumpy reunion.
* The events of the first ''UruseiYatsura'' movie, ''Only You'', were set in motion when as a child Ataru played a game of shadow tag with a girl who turned out to be an alien; it is a custom on her planet that stepping on someone's shadow counts as a marriage proposal. 11 years later she turns up with an interstellar battleship to claim her husband...
* According to some side materials, a very young Dorothy Catalonia from ''Anime/MobileSuitGundamWing'' made one with her distant cousin and her father's favorite pupil, Treize Krushrenada. [[spoiler: We don't know if Dorothy wanted Treize to fulfill it, though she ''did'' show affection for him. And apparently it did not seem to matter, considering that he died at the end of the series.]]
* In Manga/AxisPowersHetalia Holy Roman Empire to North Italy. [[CrowningMomentofHeartwarming D'awwwww...]] [[spoiler: Which, if the "Germany is HRE" theory is correct, makes Germany's awkward proposal in the Valentine's Day strip]] even more sweet and hilarious.
** Another one for North Italy, though this one is a bit weird. When N. Italy and Romano were little kids Spain was an adult already. Spain said he would marry N.Italy when N.Italy grew up (and gay marriage was legal), then Romano got upset wondering what would happen to him if they got married. Spain than says he'll marry both of them. Centuries later, Gay marriage is legalized and N. Italy doesn't remember his promise to Spain, so Spain dejectedly tries to ask Romano. Romano doesn't say no, but he doesn't say yes either. And it's never mentioned again.
* ''Boku Wa Imouto Ni Koi O Suru'' features a marriage promise between [[FatherIWantToMarryMyBrother Yori and Iku]]. Despite the fact that they're [[BrotherSisterIncest twins]] they later decide to make good on the promise.
* In ''MaisonIkkoku'', Yusaku Godai made such a promise with his [[KissingCousins cousin]] Akira, who in the present day is taking care of Yusaku while he's in the hospital with a broken leg. He's worried that she remembers the promise and will try to keep it, [[spoiler:but actually she's secretly engaged to another guy who she's planning to elope with]].
* In ''{{Nisekoi}}'', the main character Ichijou Raku wears a pendant with a lock from the time he was 5 years old. He spent summer playing with his first love and when they had to say goodbye, they promised to each other that when they meet again when they're grown up, they will open the pendant using her key and get married. Things get complicated because [[spoiler:he spent that summer with three different girls and made the same promise to all of them]].
* A bonus story in ''HalfPrince'' shows that Zhou/Wicked fell in love with Lan when she (then twelve) asked her to marry him.
* Eita and [[spoiler: Ai]] do this in ''LightNovel/OreNoKanojoToOsananajimigaShurabaSugiru''. While he totally forgot about it, she remembered it very well, and even shows him the "marriage certificate" they made as kids. HilarityEnsues as he runs from her while she tries to get him to stamp the certificate.
* ''InfiniteStratos'' had Ichika promise that when she was a better cook, he would eat [[AnimeChineseGirl Rin's]] sweet-and-sour pork every day. Unfortunately for her, [[CluelessChickMagnet he took that promise in a literal sense.]]
[[/folder]]


[[folder:{{Comics}}]]
* Countess Gwendoline and Roderick in the ''DouweDabbert'' story ''Florin the Loafer''. Very inconvenient for the villain who wants to marry Gwendoline to become a count.
* The plot of the comics in the Daily Planners line ''Artilugia'' is based around the tween heroine Aldonza creating the titular SexierAlterEgo Artilugia as a way to secure her marriage promise with her beloved Bruno, whom she believes is being seduced by the AlphaBitch of their classroom. The resultant situations becomes an ImaginaryLoveTriangle when seen from her perspective, and a TwoPersonLoveTriangle if seen from Bruno's.

[[folder:Commercials]]
* A candy commercial a few years ago featured a little boy asking a little girl to marry him, and giving her a Life Saver as an engagement ring.

[[folder:Fanfic]]
* In Roleplay/DCNation, the [[http://community.livejournal.com/jla_watchtower/749066.html "42 Days" Flashback]]. Forty-two days into sobriety, homeless, and with nowhere else to go, Roy shows up on Donna's doorstep.
-->'''Donna:''' "I swear upon the Styx that I will never look upon you with hate. Nor will I leave your side if you feel in your heart I belong there."
** At the time, neither one really understood the implications of that vow. Between the Titans of Myth and Dark Angel, the two parted. Roy ended up the UnluckyChildhoodFriend when Terry Long came into the picture, and had a wonderful train-wreck of a relationship with Cheshire. Almost twenty years, [[http://community.livejournal.com/jla_watchtower/860785.html an acrimonious divorce (hers)]], [[http://community.livejournal.com/jla_watchtower/tag/cheshire a couple of murder attempts by his ex]], [[http://community.livejournal.com/jla_watchtower/tag/olympics a naked trip into hell]], a couple fights with [[http://community.livejournal.com/jla_watchtower/tag/dark angel Dark Angel]], and a return from the dead for both later...[[http://community.livejournal.com/jla_watchtower/1022495.html They finally get there]].
* Happens ''[[SeenItAMillionTimes a lot]]'' in ''Series/DoctorWho'' fanfic, between Kid!Doctor and [[UsedToBeASweetKid Kid!Master.]]
** This also shows up in stories that show Amy and Rory as children.
* In the ''WesternAnimation/RiseOfTheGuardians'' and ''WesternAnimation/{{Megamind}}'' crossover fic ''[[https://www.fanfiction.net/s/8772736/1/Protectors Protectors]]'', we get a very heartwarming example when the group of children, including Kid!Roxanne, defend Kid!Megamind (known as Teal here) from two [[ManipulativeBastard Manipulative Bastards]].
-->'''Roxanne''': Teal is my very best friend in the world, and one day, I'm gonna marry him!

[[folder:Film]]
* Mary Hatch promised George Baily that she would "love him til the day she died" in ''ItsAWonderfulLife'', although she whispered it into his deaf ear so that he couldn't hear her.
* A young ''Film/ForrestGump'' and Jenny fall in love as children, in the shadow of, if not TheWorldTree per se, then at least a very very large tree.
* ''SweetHomeAlabama'' starts with a memory/{{dream sequence}} of the main character and her childhood friend promising to marry each other. The backstory shows that it didn't end happily. They ''did'' get married, but soon found it wasn't as glamorous as they thought it would be. After a [[spoiler: miscarriage]], Melanie leaves for New York, where she spends the next seven or so years building a fashion business. It's when she wants to marry again she runs into problems...she and her childhood romance never divorced; he refused to sign the papers. After a return to her roots and an analysis of just why their marriage failed [[spoiler: he signs the divorce papers, only to find at her wedding that ''she'' hadn't signed them. She realizes she's still in love with him, not her new fiance. They decide not to get divorced, after all.]]
* In ''Mongol'', Temudgin, otherwise known as Genghis Khan, picks out his arranged bride, Borte, when he's little. Guess who is his LoveInterest and who he obsesses over for the rest of the movie?
* In ''East of Eden'', Aron promises to marry Abra under a willow tree, and they even act like they are married, but then [[spoiler: Aron goes off to war and gets killed. Abra ends up with Cal, Aron's brother, who she had grown to love while Aron was at college]].
* In ''Film/StarWars'' Anakin tells Padme that he's going to marry her someday. Considering his abilities as a seer, this could either be a childhood marriage promise or stating what he sees as fact.
** Or perhaps its foreshadowing to Anakin's arrogant and demanding nature, and he's simply making a promise.
* Twelve-year-olds Sam and Suzy get unofficially married in ''Film/MoonriseKingdom''.
[[/folder]]

[[folder:Literature]]
* Subverted in TeresaEdgerton's ''[[{{Celydonn}} The Castle of the Silver Wheel]]'', in which [[TheWisePrince Prince Tryffin]] pulls a SpeakNowOrForeverHoldYourPeace in the nick of time to prevent Gwenlliant from being forced into an ArrangedMarriage with a notoriously abusive man. When asked if they have a ChildhoodMarriagePromise (which would constitute a pre-contract, thus acting as an impediment), Gwenlliant claims that they do - because Tryffin CannotTellALie, so she has to do it.
* Scout and Dill in ''Literature/ToKillAMockingbird''. Scout was based on the author, Harper Lee, while Dill was based on her childhood friend, Truman Capote, author of ''Literature/BreakfastAtTiffanys'' and ''In Cold Blood''. Incidentally, Capote was gay, and Lee never married.
* In Naomi Novik's ''{{Temeraire}}'' series, Lawrence and a girl he knew made a half-serious marriage proposal when they were young, just before he went off to join the Navy. When he became an aviator in his mid-twenties, his prospects and suitability greatly reduced by it, they sadly called it off.
* Nikolai and Sonya in ''Literature/WarAndPeace''.
* 10-year-old Tommy Bangs and Nan Harding plan to get married in ''[[Literature/LittleWomen Little Men]]''; ten years later in ''Jo's Boys'', Nan can't believe Tom still expects her to go through with it. [[spoiler:They don't; she remains unmarried but happy as a HotLibrarian, and Tommy marries his other suitor Dora.]]
* The book ''Quest for a Maid'' has a scene where the 10-year-old heroine Meg rescued a 6-year-old boy, Davy, from some bullies. Davy was so grateful he asked her to marry him on the spot, and she accepted. His father overheard, and while acknowledging it was just kids playing, decided this was perfectly suitable, talked to Meg's father, and made it an ArrangedMarriage. Davy became the UnluckyChildhoodFriend later, though, when Meg reached the age when she was ready to marry but realized that Davy was still too young,and she didn't want to wait.
* In ''Hetty Feather'' by Jacqueline Wilson, Hetty's older foster brother Jem promises to marry her when they are grown up so that she can rejoin the family after being sent back to the Foundling Hospital. A modern-day version happens in ''Kiss'', where Sylvie and Carl had such a promise as children, but [[spoiler:Carl comes out as gay.]]
* In Morris Gleitzman's ''{{Bumface}}'', the two main characters actually ''get married'' as children, in order to circumvent an ArrangedMarriage.
* In ''The Exiles'' series by Hilary [=McKay=], 10-years old Rachel is so enthralled by the nice, polite and charming French exchange student Philippe that she announces she's going to [[SingleWomanSeeksGoodMan marry him]] when they're older. When her sisters scold her for harassing Philippe, she just smiles and says that he hasn't said that he ''doesn't'' want to. [[spoiler:She gets him in the end.]]
* In ''BloodyJack'', Jacky and Jaimy promised to get married someday back when they were children on the ''Dolphin''. They still intend to go through with it, despite being totally unsuited for each other.
* Rand al'Thor and Egwene al'Vere of the WheelOfTime were all-but promised to each other. They each muse on it in their internal monologues as one of the more amusingly nostalgic parts of the world they'd left behind once they'd assumed the mantles of [[spoiler: [[DarkMessiah Dragon]] [[PersonOfMassDestruction Reborn]]]] and [[spoiler: Amyrlin Seat]], respectively.
* In the novel ''Zinnia'', Zinnia and Tate do this. They fully intend to go through with it, having been close friends for years, but a black woman and a white man in 1922 get hatred from all sides. They try to date other people. It only works for one of them. Who that is goes back and forth a few times before a complicated BittersweetEnding.
* [[TheAdventuresOfTomSawyer Tom Sawyer and Becky Thatcher]], somewhat complicated by the fact that she's not the first girl he was ever engaged to. And that [[{{Tsundere}} Be]][[ClingyJealousGirl cky]] gets PISSED when she finds out.

[[folder: Live Action TV]]
* In the episode ''Jack in the Box'' of ''Series/JonathanCreek'', the character of Jack Holiday proposed to his child co-star (implied to be as a joke), but then on returning after ten years, [[AllGrownUp met her again as an adult]] and married her. [[spoiler:He then hires a man to kill her.]]
* Turns out to be the whole cause of the plot of ''HarpersIsland'', after [[spoiler:nine-year-old Abby told eleven-year-old Henry that she wanted to live alone with him forever on the titular island. Sixteen years later he tries to hold her to this - by luring her to the island on false pretenses, murdering all third parties and faking their deaths. She doesn't see the romantic side. To say nothing of the fact that he later found out they were [[BrotherSisterIncest half-siblings and didn't let that affect his feelings]].]]
* In ''Series/ToshiieToMatsu'', Matsu and Toshiie promise themselves to each other when Matsu is quite young (one source says she was only 11-ish at the time).
* The live-action segment of one ''SuperMarioBrosSuperShow'' episode plays with this: Mario receives a letter from one "Roxanne", reminding him of "his promise" made 15 years prior. Mario and Luigi are both assuming it's along the lines of this trope, but at the end it's revealed that Roxanne is already married with five kids; Mario's promise was instead to sell her plumbing supplies at wholesale price.

[[folder:Theater]]
* OlderThanTelevision: Creator/GilbertAndSullivan operettas used this trope repeatedly.
** ''Theatre/TheGrandDuke'' (1896) has plot involving dueling to the ''technical'' death by cutting a deck of cards is a bit ''Franchise/YuGiOh'' to make the subject of a proto-musical. Suffice to say that Ludwig is saddled with all the commitments of the people he beats at cards, and they turn out to involve a lot of romantic ones. Once he's been forced to marry his third wife... well, it seems like he should have skipped that third one, when the woman the Grand Duke was engaged to in infancy shows up.
** This trope's central to the plot of ''Theatre/TheGondoliers''
** ''Theatre/PrincessIda'' devotes an entire song, "Ida Was a Twelve-month Old," to this:
-->''Ida was a twelve-month old,\\
Twenty years ago!\\
I was twice that age, I'm told,\\
Twenty years ago!\\
Husband twice as old as wife,\\
Augurs ill for married life;\\
Baleful prophecies were rife,\\

* A side quest in ''JadeEmpire'' involves sorting out one of these, with the twist that the UnluckyChildhoodFriend trying to cash in on the promise has grown up to be the leader of a gang. Fortunately, you can not only convince her to let it go, but you can also [[MatchMakerQuest find a suitable husband for her.]] Or, if you're in the right mood, convince her to kill her romantic rival, followed by accidentally killing the one who made the promise. And then she realizes what she's done, breaks down and attacks you, resulting in you killing her and her entire gang.
* ''Franchise/TheLegendOfZelda'':
** Link has found himself engaged in this way to the [[FishPeople Zora]] Princess Ruto (who does grow up to be [[CuteMonsterGirl rather easy on the eyes]]) in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' and the Maku Tree in ''[[VideoGame/TheLegendOfZeldaOracleGames Oracle of Ages]]'', even though [[HeroicMime he never really agreed in either case]].
** Also in ''Ocarina of Time'', Talon brings up the idea of [[ArrangedMarriage engaging Link to his daughter Malon]]. Link can actually say yes, but either way Talon claims to be just kidding.
** In ''[[VideoGame/TheLegendOfZeldaMajorasMask Majora's Mask]]'', Kafei and Anju had one of these, promising each other to exchange wedding masks on the day of the Carnival of Time which according to Termina tradition was the best day for couples to be married. The promise proves so meaningful that Kafei refuses to reunite with Anju without retrieving his wedding mask (the Sun's Mask) from Sakon, who stole it shortly before the events of the game began.
* In ''{{Palace Hotel}}'', one of the stories from the expanded universe of the ''{{Halo}}'' series, it is revealed that John-117 (The Master Chief) had a childhood friend named Parisa. The two became friends after John saved her from drowning in a lake, and later John promised to marry her and keep her safe. He was [[spoiler:never able to keep it, however, as he was abducted two weeks later for the Spartan Program and replaced with a flash clone which died not long after. Due to this, Parisa believed that John had died, though she kept with her a picture of herself and John taken by their parents. Years later, John would meet her again during the Battle of New Mombasa. At the time, Parisa was holding the picture of herself and John as children [[http://images.wikia.com/halo/images/4/44/Evo_PHotel_Chua.jpg as seen here]]. Just as John was intending to remind Parisa to not bring personal items to a combat zone, he recognized the picture. Parisa, obviously not recognizing John because of his armor, explained the story behind the picture to him and said that although it was silly and John was "dead", she intended to hold him to that promise. Despite the sudden flood of memories, John couldn't bring himself to reveal who he was, knowing that doing so would be a massive security breach. Instead he maintained his stoic facade and the two of them began planning a counterattack on the Covenant.]]
* In ''VideoGame/{{Persona 3}}'' one of the [[LevelUpAtIntimacy5 Social Links]] ending involves a little girl (Maiko) who promises to marry the High School protagonist when the time comes. In [[ExpansionPack FES]] the protagonist may later on be met by her father, who heard of this from a letter from his daughter and accuses you of trying to pull WifeHusbandry. [[spoiler:Not that it matters because you die within the next two days]].
* If the player maxes out his cousin Nanako Doujima's Social Link, at the end of ''VideoGame/{{Persona 4}}'', on the last day before you leave the town Nanako will promise to marry you when she grows up. Her father Ryotaro for the most part laughs it off as something she's just saying because she'll miss you, but he makes it clear that she is off-limits no matter what age any of you are. However, if you maxed out Doujima's Social Link... well, [[KissingCousins he's going to hold you to that.]]
* In ''VideoGame/TalesOfTheAbyss'', Luke and [[KissingCousins his cousin Natalia]] made a mutual ChildhoodMarriagePromise at a young age. Shortly after, he was kidnapped and lost all his memories, forgetting all about it.
* ''FireEmblem 7'' (the first released Stateside on GBA) has Priscilla and Raven, which looks kinda cute until you realize that they're [[BrotherSisterIncest siblings]].
** These also happen in supports, if you squint. One example from ''VideoGame/FireEmblemTheSacredStones''. Note that these two could be anywhere from the age of [[ChildSoldiers 12- 15 at the time of gameplay]]:
--> '''[[NiceGuy Franz:]]'''I don't know what it is you plan to do with your life, but as long as we travel the same path, would you let me walk beside you?
-->......
--> '''[[NaiveEverygirl Amelia:]]''' ...let me be your shield to protect you...
--> '''Franz:''' And I will be your sword and fight for you. From now on.
** Amelia's other two romantic endings also involve said promises: [[HotBlooded Ross]] will ask her to help him reconstruct his DoomedHometown and settle down with him, [[ChildMage Ewan]] will promise to take her with him as he goes WalkingTheEarth. Since they also happen at the A support time, the endings will have Amelia accept and live happily with any of her three possible husbands.
* In ''VideoGame/RuneFactory2'', the second game in a spin off series of HarvestMoon, in the second half of the game in which you play as your child, you propose and "marry" your boyfriend/girlfriend (''s'' in the case of Serena and her twin, Sera). Though, it's just a promise that you will marry them in the future.
** Except in Serena and Sera's case when you play as your ''daughter''. You are stopped due to the priest saying how "girls can't get married to each other"(and how the twins just think marriage is one big tea party in the English version).
** ''VideoGame/RuneFactoryOceans'' also features one [[spoiler:between Aden and Sonja]], but it's never brought up unless the former proposes to the latter.
* In ''HarvestMoon: Back to Nature'', the goal of the game was to revive your dead grandfather's old farm that you had been to as a child. While there, you met a girl and promised to come back and marry her.
* In ''Zone of the Enders: The Fist of Mars'', when Cage is reunited with a group of orphans he saved earlier in the games, one of them reiterates the promise to marry him when she grows up. This earns Cage a nasty look from Myona.
* Subverted in ''MagicalDiary'' in that neither party has any interest in going through with the promise... except that [[AccidentalMarriage the choice may not be up to them]].
* In ''VideoGame/{{Castlevania 64}}'', [[spoiler:in Carrie's bad ending, [[CreepyChild Malus]] gets [[KidHero Carrie]] to make a promise to marry him when the two are old enough... and then ominously says, "Now we have a binding contract..."]] For those not in the know, [[spoiler:''Malus is Dracula'': essentially, the promise is the cornerstone of UnholyMatrimony ''and poor Carrie hasn't the faintest idea''.]]
* In ''Aggressors Of Dark Kombat'', [[CuteBruiser Kisarah Westfield]]'s reason to enter the ADK tournament is that she wants [[TheHero Joe Kusanagi]] to acknowledge the one they made as children. She succeeds, but only [[http://www.vgmuseum.com/end/neogeo/b/agreki.htm in her own ending]]. [[spoiler:And in ''VideoGame/NeoGeoBattleColiseum''.]]

* A variant in ''VisualNovel/UminekoWhenTheyCry'': [[spoiler:Battler promised to Shannon that he would "come back to take her away on a white horse". She remembered it [[IWillWaitForYou and waited desperately.]] He didn't return to the island for six years and completely forgot about her, not only having not taken that promise as seriously as Shannon did, but having been held back by MASSIVE family problems.]] [[ButterflyOfDoom It snowballed into]] [[KillEmAll a horrible tragedy for the Ushiromiya family.]]
* In VisualNovel/TrueLoveJunaiMonogatari, there was one between the main character and [[spoiler: the local {{Tsundere}} and PatientChildhoodLoveInterest, Mikae Morikawa. The PlayerCharacter, as a little boy, repeteadly swore that he'd make Mikae his bride; as they grow up, he never really forgets it... and if he pursues Mikae, he's surprised to learn that she not only remembers it, but deep down always wanted him to fill it.]]

* Webcomic/MeatShield: Not so much a promise as a crazy girl convincing herself (and a chunk of the town) that Dhur was going to marry her.

[[folder:Real Life]]
* Here's a sweet RealLife example: two German children, 5 and 6, tried to go to take a trip to Africa so they could marry one another. Although they failed to, there must obviously be a promise to try again in the future. The story can be read [[http://news.bbc.co.uk/2/hi/europe/7811686.stm here]].
* The story goes that WolfgangAmadeusMozart proposed marriage to MarieAntoinette when both were children (he had just performed for her family). In the event, each married someone else.
* St. Elizabeth of Thuringia, the daughter of King Andrew II of Hungary, was betrothed to the 10-year-old Louis of Thuringia at the age of 4; they were married 4 years later. [[PerfectlyArrangedMarriage Their marriage]] [[VictoriousChildhoodFriend was extremely happy]] until Louis died on [[TheCrusades crusade]]. She [[ScrewThisImOuttaHere left the Thuringian court]] to escape [[BigScrewedUpFamily the family intrigues]], died at the age of 24 [[PrincessInRags in (most likely self-imposed) great poverty]], and was canonized 4 years later in 1235.
* Explorer [[http://en.wikipedia.org/wiki/Ranulph_Fiennes#Personal_life Sir Ranulph Fiennes]] (a cousin of the actor [[TheEnglishPatient Ralph Fiennes]]) met his future wife when she was 9 and he was 12. They remained married for 34 years.
* Just recently in Denmark, a very young couple, both 18 years old, got married. Turns out that they've known each other since kindergarden and around their early teens started dating each other after remembering that they made a promise. Surely a CrowningMomentOfHeartWarming!
