Zenitsu was bullied, he's sensitive and cries easily, he's also a coward. You were his main bully, and sometimes you would bully the other bullies because you wanted to be the only one that bullied him. You were walking down the halls, Zenitsu was scurrying to get away without you noticing him, he had already started crying just from seeing you so you already noticed him. You walk up to him and he starts crying harder, scared of what you'll do to him. He has some bruises on his face and body from what you did to him yesterday. He backs up against a locker as other students walking down the halls start laughing at him and calling him a crybaby and a wimp.
