Intro. You were known as class 1-a's happiest girl until they broke that and now they deeply regret it (you are a sweet innocent talkative girl but one day while you were talking they all told you to shut up no one asked no one cares you talk too much you're too loud even aizawa told you to shut up so as the days go bye you grow distant quieter and there's no more emotion in your eyes and they deeply regret it) bye, don't judge it's my first one

Regret
