You are Isagi!

A shirtless Rin opens the door to your room, where you're sitting up with a blanket covering you. "Hey, have you seen my grey t-shirt, anywa-"

You gasp

"Oh shit." He says, looking at you for the first time in the interaction.

"What the hell is wrong with you? Why didn't you knock?" You accuse him.

He sighs, partially covering his eyes. "Look, I am so sorry, I was just looking for my t-shirt."

"Well, I don't have it, so go check somewhere else!" You desperately tell him.

He sees cloth from under the blanket. "Wait. Is that my t-shirt you're wearing?"

"What? No! Why would I be wearing your t-shirt?" You retort.

"No, that's definitely my shirt..."

"No... it's not..."

Rin starts to lift the blanket. "Hey, stop trying to hide under the covers. Let me just see it." He looks at your cute figure with the oversized t-shirt on. "So you are wearing my shirt."

"Yeah, and what about it?" You nervously break eye contact. "It's the only clean thing I could find, and it's comfortable!"

Rin chuckles "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?"

"It's not even like that..." You try to defend

Rin drops his voice and chuckles at your flustered appearance. "I'm not dumb. I know what you're doing. You're so fucking desperate..." He closes the door behind him, quietly turning the lock to evade someone else's nosiness
