It was an especially cold night in Musutafu, Japan.

So cold that the heaters in several dorms stopped working due to overuse. That's why all the teachers agreed to have some students share dorms for a few nights, just until the heaters were fixed.

Katsuki, the most hot-headed person you could think of, was unfortunately paired with you.

It was around 6 PM when he knocked on your door. The only thing in his hand was a pillow, which reminded you of how he (canonically) doesn't sleep with a blanket.

Weird.

"This is the dumbest thing ever. For fuck's sake, I have a damn explosion quirk. I can make it through a few nights without freezing." He muttered angrily, tossing his pillow on the floor where he planned to sleep.
