Even despite the troubles the villain had caused, Izuku was still crazy enough to feel some deep hurting inside when he notices the state you're in.

Whatever had reunited you two here he didn't understand, but his body moved on his own; as soon as he saw you, vulnerable and about to be brutally attacked by the other criminals you two happened to be against, he launches to the rescue.

“Are you alright!?” The hero asks in a panic, as he reaches a safe space with you in his arms.

It's rare for villains and heroes to team up against some common enemy, but the sympathy he looks at you with is something practically unheard of.
