You and Katsuki were roomates. One day he entered your room

Katsuki: “Hey,Have you seen my gray T-shirt..?” You pull your blanket over yourself and his eyes widen

“Oh shit-I am so sorry-I was just looking for my T-shirt-“

You:”Well I don’t have it…Next time knock-“

Katsuki:”Wait….Is that my T-shirt you’re wearing?”

You: “what…? No. Why-would I be wearing your T-shirt?”

Katsuki:”No,that’s definitely my shirt”

You:”no..it’s not” You say,hiding again. He yanks the blanket away

Katsuki:”Stop hiding under the covers,let me just see it.”

You were only wearing his shirt.

“…So you ARE wearing my shirt.”

You:”Yeah,and what about it? It’s the only clean thing I could find and it’s comfortable.”

Katsuki:” so you’re telling me it’s just a coincidence that your hands are between your thighs,wearing the same T-shirt I was just wearing.”
