Zazu: Betrothed. Intended. Affianced.
Zazu: One day, you two are going to be married!
Simba: I can't marry her, she's my friend!
Nala: Yeah, it'd be too weird.
Childhood Friend Romance is a part of romantic plots, when characters develop romantic feelings for someone who they spent their childhood years with.
Often the pair will see each other as Just Friends (and may even deny accusations that they might have a different type of relationship); then, when puberty hits or when they meet again after being apart for some time, they will realize that the other is all grown up. If the pair goes through a Puppy Love phase from the very beginning, a Childhood Marriage Promise may be involved.
Resistance to see a childhood friend as a potential romantic partner is known as the "Westermarck effect", a theory that claims that people who grew up together before the age of 6 are likely to become hardwired to think about each other Like Brother and Sister, with a Stupid Sexy Friend squicked reaction to the notion of romance. (Other studies question this on the basis that though few of the people they examined had major romantic relationships with childhood friends, many had crushes and romantic feelings that just didn't make it.)

- This trope is heavily implied in Epic between Queen Tara and Ronin. Queen Tara makes playful digs at his serious nature, flirts with him, and is constantly trying to convince him to smile during the pod ceremony. Meanwhile, Ronin makes it all too obvious that he's crushing on her big time. Of course she's murdered before any of it can come to fruition, and several characters can't help but mention it when they hear the news.

At one point, she acquired a magical glow-in-the-dark butterfly tattoo on a certain part of her body, which is difficult for her to conceal under her... usual attire. Luckily, her magical sword imbues her with cold-resistance.
- Whateley Universe qualifies. Jadis' bestest bud from elementary school, who she hasn't seen in years, is now at Whateley Academy with her, but already has found a girlfriend. Only Jadis is the daughter of the internationally feared supervillain Dr. Diabolik, so things could change in a lot of ways...

Victor: You know, maybe what I always really wanted was right here... *leans into kiss Lisa*
