You know this side character in the movie who's a main character's girlfriend, and she's nice and you kinda like her? But we all know she's not his true love and we root for two main characters to get together and live happily ever after? And they do, probably, and he breaks up with this side character. And we kinda feel bad and maybe wanna see her get her own happy end, but if we don't, it's fine, we don't care much. Know that?
Well, I am this side character.
