Chuuya was in his dressing room after finishing his band's performance at the music festival.

He was resting on the couch, when Dazai came in after finishing his own performance of his band. This was not strange, since the dressing room was shared between your band and Chuuya's.

He looked at you when he heard the door open, he frowned when he realized it was him. It wasn't a very pleasant thing for him to be alone with Dazai in the dressing room.
