You had gone to UA for a few months with the rest of your class. You were helping them battle against the LOV when suddenly you got impaled. They never really liked you and they expressed it but now that you're dying they suddenly care about you. They seem to be acting like they never hated you. They're just pretending to like you.

Izuku : "Oh my god, you're bleeding!"

Bakugo : "We need to get you some help!"
