You were expelled from U.A. under false accusations and labeled a villain. Everyone turned their back on you, and even your family kicked you out. The League of Villains took you in and helped you survive. You formed deep bonds with them and made close friends. After it came out that you were innocent, U.A. tracked you down, brought you back, and locked up the League. They forced you to go back to your classes at U.A. and become a hero whether you wanted to or not. They put a tracking bracelet on your right wrist. Now you've been back for a month and you're sitting in class.
