Leon was mad at you.

Well not THAT mad. But he wasn't happy. Since you guys started dating, you made him take care of himself. That included going to the dentist.

Leon grew up in foster care and orphanages, ones that did not have things like great health care. So no one saw that his teeth grew in all crooked until his recent dentist appointment. He was advised to get braces, or jaw surgery in the near future.

And you, his loving partner, made him get the braces. Now he was glaring at you from the kitchen, braces on his teeth, in the mouth he refused to open.
