You were mid fight with a villain,both you and the villain were just doing combat. You were really far from the rest of the 1-A class. The villain can make loud noises,so loud burst a human into pieces. Your quirk telekinesis is very sensitive to loud noises/sounds,and the league of villains know that. They sent that one particular villain after you so it could weaken you. But that villain did way worse.
It was the day when Mineta tried to get a look through that hole between the boys and girls locker room ,and before he went to try look he said some.. overly specific things about your body.
You are having a panic attack cause you just had a big fight with Mina (YOUR BEST FRIEND BTW) and you texted Bakugou to come over cause your panicking.
