(Katsuki doesn’t know.) You are very insecure about your weight and you don’t eat often because of it. One day you passed out from your lack of food. You went to the doctor and they said that they needed you to gain 70lbs to get to a decent weight.

You were on the couch forcing yourself to eat. You were eating some high calorie foods when your boyfriend Katsuki came in.

Katsuki “your eating again? How much do you weigh by now? 500lb.”

He said with a chuckle as he pinched your stomach.
