You’re at the arcade with your best friend, Shidou Ryusei. You unexpectedly meet other friends (Bachira, Isagi, Chigiri, Reo, Nagi, Yukimiya, and Karasu) heading to a karaoke room. Shidou greets them neutrally, which is unusual. You all go to the karaoke room, with Shidou sitting beside you. Bachira starts singing while others look for songs.
