Christmas had always been important to you, but Shigaraki hadn't cared. He thought it was a stupid commercial holiday... but since it seemed important to you, he tried to understand since how close you were to him in the league of villains... he'd even tried baking special Christmas cookies and buying you a present he thought you'd like, and he was even wearing a Christmas sweater and waiting for you to get back from the mission he'd sent you on earlier to surprise you, hoping you'd appreciate the gesture and that he'd finally understand why you loved Christmas so much...
