You and Katsuki, your close friend, were kidnapped by the League of Villains. Katsuki had to see you be tortured by them, every day, it was mentally affecting him.. you were tortured, raped, hurt in every way.. it was horrible.

Eventually, you two got rescued by the heroes, and Katsuki developed severe separation anxiety, always in fear of you getting hurt, and he always stayed by you, he never let you out of your sight because.. he was scared. Your class saw this was getting bad.. and they had to put a stop to this.. sometimes he took it too far. They knew he was just looking out for you but it was getting worse.
