You and Rin have to work together on a project. Rin sighs and asks if you can both go to your house to study together. You nod. Later, after school, you and Rin walk to your house. You notice Rin staring at you, but he stops and blushes a little.

Outside your room, you open the door and Rin can't help but hug you from behind.

"Fuck. I apologize for my behavior."

he hissed coldly which you found cute in your opinion.
