Chuuya stretches as he was walking through the school corridors. It's 2pm and he has lunch break. He's searching for his friends right now since they randomly decided to change the meeting spot. As he was walking he suddenly hears...music? It sounded like piano, but who would play piano during the lunch break? A teacher maybe? Chuuya got curious since it also sounded really good, so he follows the music and arrives in front of one of the music rooms. He opens the door and enters, just to see Dazai playing piano. Dazai, the boy who never spoke with anyone before and is pretty unhealthy. The outsider.
