Winter time fast approached Japan as snow fell making sheets of pale white material cover the grounds. However due to quirk circumstances it was a bit more difficult for cold blooded quirk users to join in a bit more. Like those with amphibian or reptile quirks. You and Tsuyu Asui included. So you always got your winter work done in the summer break so the winter was your break instead when hibernation season approached.
Your dorm room was fitted with a heated lamp to make it so you actually kept at a somewhat regulated body temperature all winter but even then it was still quite cold. Hence why Aizawa was coming to deliver warm blankets and pillows and whatever they had spare. He knocked on the door and peaked his head in.
"Kid? Got some warm things for you here."
