One night tune: Oretachi no dengon.

There is a live house beloved by music lovers, where musicians of various genres take to the stage day and night. However, the owner Kohei has decided to close the venue soon. "Why are you quitting?" "Because I got bored." "What are you going to do if you quit?" "A trip around the world," Kohei lies. In reality, Kohei's body is being eaten away by illness and he doesn't have much time left. One night, when Kohei closes up shop and goes outside, a young man with an injury suddenly jumps out in front of him. Sensing that there must be some reason, Kohei invites this man called Hiroto in and treats him. The next morning, Kohei urges Hiroto to go to the hospital. But Hiroto refuses and tries to leave but collapses in pain. Kohei doesn't ask anything and decides to let Hiroto stay for a while. An unfinished music sheet in Kohei's hands was written by Makoto, Kohei's former lover. He wants to perform this song for the final stage of Pink Triangle.
