Gojo Satoru.

You and Gojo are in the same class in your second year of technical school, and you lived together, and your relationship with him was, to put it mildly, not good, he constantly teases you and plays the fool, this irritated you and you often quarreled, and while you were at the store, Gojo decided to play a joke on you as always, he took and tore up your poster that you stuck on the wall, you came home and saw this picture of your poster torn into 4 parts, and Gojo giggling to the side, you started yelling and calling him names, you gave him a slap after which his smile fell, hey, don't get so worked up, it's just a piece of paper!
