** It's common to portray canon married couple Shining Armor and Princess Cadence as having known each other since they were both foals, due to their connections to Twilight Sparkle. It's also very common for [[LesYay Fluttershy and]] [[TomboyAndGirlyGirl Rainbow Dash]], who ''are'' childhood friends, such as in ''Fanfic/HowWeMet''.
** Many writers also like to portray [[FoeYayShipping Princess Celesta and Discord]] as having a past together before Discord attempted to take over Equestria. [[spoiler:Following his reform, the writers like to think they're giving their relationship another try]].
** Following the season five finale and season six premiere, fans have started writing stories involving reformed villain Starlight Glimmer falling in love with her childhood friend Sunburst.
** In ''[[https://www.fimfiction.net/story/451657/eric-sparkle-and-the-locket-of-prophecies Eric Sparkle and the Locket of Prophecies]]'', [[spoiler:Storm Blade has been in love with Twilight Sparkle since they met in magic school when they were foals]].
** In ''Fanfic/TheFlashSentryChronicles'', Flash Sentry and Twilight Sparkle have been best friends ever since childhood, with Twilight's family taking him in after he helps her and they learn he has no family himself. Their friendship slowly evolves into something more, even if it takes them both [[ObliviousToLove a long time to realize it]].
** ''Fanfic/ThePowerOfTheEquinox'' has a tragic example with Scootaloo's adoptive parents Brutus Meadows and Vibrant Glow. They first met when Brutus became Vibrant's seatmate at school, [[AccidentalHandHold with their hooves accidentally touching each other's]]. They became married in adulthood, but they were unable to have a foal together, leading them to adopt Scootaloo. Then Vibrant became a [[TheGamblingAddict gambling addict]], eating up most of the family's money as the result. This in turn caused Brutus to became a bitter drunk and [[AbusiveParents abusive towards Scootaloo]], greatly straining his relationship with his wife. [[spoiler:Brutus ends up snapping and [[TilMurderDoUsPart killing Vibrant]], regretting it only when he himself is dying and [[MyLifeFlashedBeforeMyEyes seeing his memories of the happier times]], including first meeting Vibrant.]]
** In ''Fanfic/NightmaresAreTragic'', Moondreamer Finemare and Dusk Skyshine met as foals at school, and eventually fell so [[OneTrueLove deeply in love]] that Moondreamer's [[{{Reincarnation}} current Aspect]] [[ReincarnationRomance still loves him]] even after having been separated from him for over four thousand years.

* ''Fanfic/PassingDays'' for ''VideoGame/FateGrandOrder'' presents a subversion, because the OfficialCouple with Vy and Robin Hood all started because of Vy enjoying the Archer's stories as a child. Even though Robin Hood the Heroic Spirit never met Vy as a childhood friend, those lingering feelings did reach him because he started calling her [[AffectionateNickname "little sparrow"]] after finding out that fact.

* ''Fanfic/SeventhEndmostVision'': [[SuperSoldier Tifa]] clearly hopes for this with [[NiceGuy Cloud]]. Aerith ships it. [[spoiler: Which is interesting because, while they may have met while they were a bit older, ''Aerith'' also hopes for this.]]
* ''Fanfic/SonOfTheSannin'':
** Naruto and Hinata met under more or less identical circumstances to canon, though Shizune's intervention means that they become close friends in their early childhood instead of Hinata simply pining for him from afar for over a decade. The two of them would eventually start dating after being promoted to Chunin in chapter 31
** Kiba and Tamaki first met at age 8 when Tamaki transferred to the academy, and while they were more rivals than friends, the [[BelligerentSexualTension sexual tension]] between them is [[EveryoneCanSeeIt very obvious to the rest of the Konoha 15]]. [[spoiler:Unlike Naruto and Hinata, they don't get together until the very end of the story during a brief lull in the final battle.]]

* ''FanFic/FracturesATLA'':
** Mai and Zuko's childhood romance is detailed and spotlighted to the readers when Zuko frees Mai from the Boiling Rock and reunites with her for the first time in years.
** When we finally get to the Gaang, Aang and Katara's blossoming romance is presented to us through Sokka's point of view. [[ShipperOnDeck He approves of them getting together, and is a little frustrated that his little sister is a tad slow to completely admit to her feelings for the Avatar.]]

* ''Webcomic/NaruHinaChronicles'': Besides having a few examples in common with the [[Manga/{{Naruto}} canon manga]] (such as Naruto/Hinata, Sasuke/Sakura, and Shikamaru/Temari), it has several more examples of its own:
** Ino and Choji have been friends since they were kids. Then, during a vacation arc, one thing led to another and they're now a couple ([[RelationshipLabelingProblems although it took quite a while for Ino to openly refer to Choji as her boyfriend]]).
** Neji and Tenten also became friends during their childhood. Many years later, they became a couple after [[RescueRomance he defended her against her ex-boyfriend Yori]] and they're now married.

* Sayaka and Kyoko in ''Fanfic/AdviceAndTrust'' have been best friends their entire lives and were engaged in a SecretRelationship at the time the series began (which later develops in to a polyamorous relationship with Kensuke). Sayaka actually mentions at one point that they've been in love with each other since before they were old enough to talk.

* ''Fanfic/SecondBiteOfTheCherry'' has Wei Ying and Lan Lan. Lan Zhan immediately decides Wei Ying is his when they first meet as preteens. They spend the following decade growing together in the Cloud Recesses, and officially tie the knot when they're shy of eighteen years old.
* In ''Fanfic/GoldPoisons'', Lan Xichen has been in love with Nie Mingjue so long that he doesn't actually know when he started having feelings for him. By the end of the fic they're together.

* ''Fanfic/TheDemonicSetoKaichouIsMyValentine'': This is a part of TheReveal: Miku and Len had knew each other since they're children, but [[spoiler: Len lost his memories of Miku after his head hit a rock when they fell from a cliff.]]

* A onesided variant appears in ''Fanfic/MarriedToTheKoopaKing''. Bowser has fond memories of being Peach's childhood friend, but Peach quickly outgrew their friendship. The fic routinely teases that Peach could requite Bowser's VillainousCrush in the future.

* ''Fanfic/TheChildOfLove'': In the sequel [[OriginalCharacter Takuma Satori]], a boy who met and befriended the first Rei for a short while when they were little kids, shows up. Takuma had a crush on Rei, but whether he was unlucky or victorious is not known due to the sequel being unfinished.

* ''Fanfic/MirrorsTLOZ'': Sheik explicitly states that Link was his childhood friend and childhood crush. Though he worries that Link only likes "Zelda", it works out between them.
