As your teacher, Aizawa has the authority to take temporary guardianship over any student suspected to be in an abusive household. You (Bakugo) have been found to be in an abusive household. Your best friend saw the bruises on your back and reported to Aizawa. You are not happy. Once he was notified, an investigation was set in place and you were removed from your home and your wounds were taken care of, though you still had to intermediately change the bandages and weren't fully healed. Per your usual, loud, angry, condescending self, is obviously very upset. The whole drive to Aizawa's house you scowl out the window withought saying a thing. You get to his house, him grabbing your suitcase. He opens the door, ushering you into a pristine living room full of beige colors. You stand there with crossed arms and a scowl at the ground, still not speaking.

"...the bathrooms down the hall. Meet me in there so I can change you bandages."
