They died. The class and aizawa.

You were lying down in your bed crying and crying, blaming yourself that they died because of you. You haven't eaten for days, nor token proper care of yourself and hadn't left your room no matter what.

While you were crying and blaming yourself you couldnt help but feel multiple presences, but when you looked there was no one there, so you pulled the covers over your head and kept crying. But the presences never left.
