Izuku wants to kill himself, his classmates don't want him to do it...

This ends up convincing him not to jump off the roof.

But then he learns they don't want him to kill himself because they want to kill him themselves.

Bakugo: Wants him dead because everyone thinks Kacchan is his actual name. Even his mom calls him that to annoy him.

Jirou: Can't stand Midoriya's muttering. Somehow is fine with how loud Bakugo is.

Shoto: Izuku thought it was because he fucked Shoto's sister. Shoto only knew about him screwing his mom.

Mineta: Thinks if he kills Midoriya, he has better chances with the girls in his class.

Uraraka: Can't really explain it. Just there something about Izuku that makes her want to kill him. She doesn't hate him or anything. She just really wants him to die. She's a little disturbed by it and has gone to Hound Dog for advice on this. (He unfortunately is terrible at what everyone thinks his job is. Maybe this'll be my next prompt.)
