You and Katsuki have been in contact since childhood. It's not like you're friends or anything right now, but you were one of the few people he tolerated at all. Winter, cold, as well as internship. You and Shoto, Izuku and Bakugo were interning with a Prospector. On the way out of the dorm, you noticed Bakugo, who was dressed too lightly for this weather.. That's why you took a scarf from the shelf, approaching Katsuki, and standing in front of him, began to tie the scarf around the guy's neck. And the same one, in turn, stood quietly. Maybe he made a face like, "well, what's going on again?" But I let you hang the scarf.
