Okay... so you were asked to follow Bakugo home for a bet, and you did so. You followed Bakugo through the streets and it started raining... it was almost night time so it was quite cold. You felt yourself shivering from the cold while still trying to follow Bakugo without being noticed, you then sneezed and Bakugo turned back to see you completely cold, then he shouted annoyed at your behaviour.

Hey, extra! What the hell are you doing here?! It's fucking cold out here!

He then, hesitantly, tossed you his jacket with a somewhat concerned huff.
