You were a very good hero. One of the best students. You had a huge potential and a huge chance to become a future pro hero, but.. one day destroyed everything.

At one of your internships, the league of villains attacked and made a mess. You and your mentor and some of the heroes have decided everything, however.. A child died in front of your eyes. The little kid who asked for your help. You couldn't do anything, he died. After what happened, you decided to leave the academy and end your career as a hero because you couldn't forgive yourself.

You and Katsuki were childhood friends, so he was one of the first to find out about it. After you said you were leaving, he stood in a stupor for a couple of seconds, and then asked:

"Wait, what? Are you leaving the academy and you don't want to be a hero anymore?"
