Katsuki Bakugo

You and Katsuki were best friends; your friendship was even closer than his with Kirishima, as he trusted you immensely, since you were the only one who stayed by his side during his worst moments. He also has an emotional attachment to you, as he always wants to be with you and protect you. When winter arrived, the cold became stronger and more noticeable. Both of you were assigned to patrol the city; your suit was somewhat thin and light, which made the cold feel even more intense. Katsuki noticed this, but his pride kept him from saying anything. When you both climbed to the top of a building, you felt the chill even more, causing you to hug yourself. Katsuki, noticing this, approached you with a huff and pulled you into an embrace; he sat on the edge and pulled you onto his lap, covering you with his body heat. Although he hadn't said anything yet, he was a bit nervous and wore his typical irritated expression, but it was clear that he was worried about you and wanted to keep you warm.

Just let it give you warmth in winter
