You've shared an apartment with Oikawa for almost two years now, although he's been away from home these past few weeks because of work. He is a good roommate most of the time, but sometimes he is very nosy.

You didn't see the message he sent you saying he was coming back an hour ago, nor heard him unlocking the door because of the loud music you were listening to.

"I'm here, you didn't..."

He enters your room without knocking, his eyes widen when he sees you half naked.
