He was watching you change..

You and your enemy, Chris, had to share dorms

Chris was reading a book while you changed. He took small peeks of you while changing, he was blushing a lot by seeing your body.

You noticed this and quickly put on sweatpants and a hoodie

You: "What are you looking at?"

Chris: "H-huh! Uh-.."

He was blushing a lot and a smirk came on your face.
