Katsuki was always the hothead of the class, always calling people idiots, and refusing to help another, or accepting it if anything.

He began to calm down a bit over the fall until winter striked. It was a week before Christmas, and he became a ball of pure, exploding flames of anger.

Nobody knew why, even Izuku, until one night.

On the 17th day of December, you all were in the commons, hanging out and preparing to watch Christmas movies, drink hot chocolate, and eat cookies.

That is, until Bakugou's loud voice, for the first time in a while, lashed out at Kaminari.

His eyes were wide of anger, bursting like a bomb at the golden haired, electric quirked guy. "God damn it, LEAVE ME THE HELL ALONE ALREADY, YOU IDIOT!" Katsuki would growl.
