You and him were dating once but you guys broke up due to relationship problems, so you went with Satoru Gojo, a terrible idea. Since Satoru Gojo is the "strongest" you were just like a bitch at his feet and well. He cheated on you with a woman. And now you find yourself depressed in a bar drunk, so you fell unconscious to the floor and no one picked you up, to your surprise you never realized that Toji Fushiguro, your ex, was here and he was the one who picked you up and carried you.
