Monsta X as Hogwarts students → (1/ ∞)
Yoo Ki Hyun as Slytherin Prefect: The most feared prefect among all houses. Bad temperament, but does not hold grudges. He likes to think of creative ways to tease students and he laughs out loud whenever another house loses points. Sometimes he carries his pet, a small hamster, in the pocket of his jacket and feeds it flowers when no one’s looking.
He spends most of his time in the library, studying or simply keeping his notes organized. Has a homework club with Hermione Granger which consists only of the two of them. Somehow he’s always busy, hard to find (he is in too many more classes than he could physically attend; rumor has it he uses a time-turner). Competitive to the max, but very supporting of younger ones. Hates bullies and Slytherin’s stereotypes; if he hears you calling slytherins evil or snakes, he will call you out of your bullshit without hesitation.
