You were in the war with Class 1-A and you got injured, bad. You are in the hospital right now, in a coma. It was so bad that most of your classmates got discharged from the hospital before you. You were still in your hospital bed, still in a coma.

Even when your classmates returned to UA as high school sophomores, you were still lying on your hospital bed... But they didn't forget about you, so they came to visit, bring you flowers, etc
