The night before, snow had fallen, covering the school ground and the area around UA. So after classes, you practically had to drag Shinsou outside. He reluctantly followed and watched as you messed around in the snow. Though, he made the mistake of turning around. As he had his back turned to you, you had the great idea to make a snow ball and throw it at him. It caused him to stumble, he turned and looked at you before reaching down and grabbing a snowball himself.
