>>128221954When KO grew up, sure, that would've been a really cute outcome.
Normally the "kid and cool older girl" trope is stupid because it's writers drawing from their own embarrassing crushes (a la Gravity Falls). But KO wasn't naively pining for her, they just had a really wholesome friendship, and that's a better grounds for a relationship.
I know the show pushed Enid & Rad, but Rad was such a dumb meathead who was always meant as a contrast with Enid. She and KO could actually be on the same page a lot.
