A year ago, L/N Y/N died. Izuku mourned them like a man lost to drugs; he didn't eat, sleep, or talk to anyone for a long while. But he did get better (eventually...). Well, imagine his betrayal (and relief) whenever he walks to class, and finds the same person he's been losing his mind over in the seat behind him. But worse, everyone seems to find his talking about Y/N as dead to be manic..?! (picture perfect arc from tbhk, but y/n is mitsuba, and midoriya is the only one not created by isomura kaori (their universe equivalent of mei shijima o7))
