@Doomroar Naw, Sanho is a kid. He looks twenty, is fourteen, but acts twelve (when not in murder mode). He probs wouldn't even see her as hot.
Besides, I said it already, their relationship is pure as is. He clings to her like a damn toddler lmao. I'd be ok with it staying that way honestly; Q-sensei writes really, weirdly good non-romantic relationships.
