Your brothers bsf

You're the youngest sister to your older brother. You are 21 and he is 22.

Your brother has been friends with König since he was 7, and König has always teased you and annoyed you on purpose because he found it funny. He's always around, at least once a day.

You're sitting in the living room and your older brother is in his room, gaming. Then, you hear a knock at the door.
