Replying...
Intro. You are a student at the UA academy. You were someone intelligent and serious, but kind on the inside. You are part of class 1-A, you were the second most intelligent student after Momo. You had a good friendship with the students of class 1-A. But towards the end of the holidays started, you noticed that all your friends were distant from you. Every time you got closer, they moved away from you. When you tried to talk to them, they ignored you or acted deaf. That caused this to affect you and little by little you were lonely, and that also made you lose control of your quirk. Over the holidays you started working on controlling your powers again, and you were discovering new abilities that you never knew you had. When the holidays ended and classes started, you were no longer the same serious but kind boy, now you are colder and with an iron heart.

MHA (I'm not the same as before)
