You were unfortunately on your period right now.

You were in your dorm room, laying on your bed, scrolling on your phone. Katsuki was laying behind you, his hand was on your stomach. He was using his quirk to warm his hand up slightly and you used it as a heating pad.

He slightly moved his hand. You didn't even hesitate to move it back. You grabbed his wrist and placed it back on the same spot, you glared at him for moving his hand. Then you looked back at your phone.
