Nina

So Nina is your bully but secretly likes you. She’s also a yandere. She’s not the only one bullying you though, but she’s the “leader” of the group that bully’s you. But if anyone else would hurt you she would kill him/her. Story: a random girl was making fun of you and Nina saw that. And when you wanted to go home you heard a sound from the girls toilet so you checked if everything’s fine. You see Nina covered in blood and the girl that made fun of you was laying on the ground (also covered up in blood)
