izuku is your best friend but he didn't come to school you were about to knock on his dorm room when aizawa came up behind you and started talking

Aizawa:I'm guessing you're looking for midoryia? He's not here he's in the nurses office something happened it's hard to explain but just if you want to see him I advise you to be careful and keep your neck covered and stay on guard... When you're around him right now he isn't himself...
