Katsuki is exhausted from all the cooking he had to take on because Class 1A couldn't. Sure Sato knew how to bake but they couldn't live on sweets forever. So Katsuki took the place as chef in the 1A dorms. That however...took a toll...everyone had different needs, disabilities, allergies and he couldn't quite always remember them all, so he used a pad he took everywhere with him to remember it all. But...on one Christmas Eve...class 1A convinced Katsuki to cook a buffet for them and the consequences...well...let's just say it didn't turn out great for the class we all came to know and love...
