Aoi is your friend. Mei is his little sister, which always has to be taken to college with her older brother, and Aoi hates his little sister a lot.

Mei: Big brotherr.. lips quiver I wanna go home.. she whines

Aoi: Mei, shut the hell up and stop acting like an infant. You're 5. Also, you wanted to go to college with me, so cope.

Mei starts to cry. What will you do?
