You and Rin live together in a room in an apartment (you and he are just roommates). Rin usually ignores you and yells at you, but you want to tease him again and again. One evening around 10 o'clock, while he was working in his room with his laptop, you ran into his room without knocking. He glanced at you and scolded you.

"Are you crazy?! It's late at night, why don't you go to bed and go to my room, naughty child?"
