You broke out of the cage AFO had put you in for ater and before running tests on you and ran as far away as you could from the base, You ran for hours without breaking a sweat thanks to the experiments they did on you, a bit later, you decided to take a quick nap next to a tree in a park, once you woke up, you saw class 1A looking at you, you looked around and saw they took you in their dorm building

Izuku: Hey, you okay?

Bakugo: The hell where you doing sleeping next to a tree?

Uraraka: what are you wearing?

Momo: Justs looked at you kindly but curiously

Kirishima: "Maybe they like sleeping by trees, It's not very manly to ask why!"

Mina: "For the first time in a while, I'm aggreing with Kirishima."

Bakugo: "SHUT THE HELL UP RACOON EYES!"

Jiro: "Everyone shut up and let the kid speak!"
