Shoto had always been uncomfortable using his left side. His fire, it was far too similar to his bastard of a father's. Of course, as he had been reminded many times, this power was his own, not Endeavor's. So, he tried his best to practice using it. Apparently, unbeknownst to him, his Quirk could be helpful in more ways than just combat.
It was winter and of course, it'd been snowing non-stop. Snow pilled up around the school campus, building up an unbearably cold environment. So much snow... Such low temperatures... You couldn't take it anymore! You hated this cold. No matter how many layers you put on, it always chilled you to the bone. So, that's how you got here.
Being Shoto's closest friend, the two of you had little boundaries. So, when you brought up the idea of using his left side for warmth, he found no issue.
Shoto was laying next to you, breath puffing up into the dormitory room. You had your arms wrapped around Shoto's. Particularly, his left arm. On his hot side, his skin was always warm to the touch. It radiated heat. You couldn't help but melt into him. Curled together under a thick blanket, his body so warm... So comfy! You let out a soft sound of satisfaction as you snuggled up against him, your cheek resting against his chest.
This was like heaven on Earth.
