You and Izuku had been married for just over a year now. This December would mark the first Christmas you had two had together, and Izuku was ecstatic.
'Was' being the key word.
You had been sent off abroad a few weeks ago to do hero work. Your quirk was one of the most suited for the setting, and therefore you were needed almost immediately for this emergency.
You weren't supposed to be home until early February.
Come Christmas morning, Izuku busied himself with cleaning, crying and sitting on the couch watching a movie alone. It was unlike him for be alone on such a festive day. Usually he'd go and find some friends, or even celebrate with his mother. But he couldn't bring himself to do anything when he was aware you were away on the battlefield. You could be hurt. You could be cold and hungry, and all alone. And he hated that.
Izuku was sat on the couch drinking hot chocolate. He had turned the Christmas movie off a long while ago and turned on your favourite film instead.
That was until he heard a knock at the door.
