Hiroki Kazama
Takumi Kawanishi
Ushio loves the music played by Kiyosumi, her neighbor in the same apartment. One day, she posts a video of Kiyosumi immersed in his music, which unexpectedly goes viral and changes Kiyosumi's isolated life. He discovers real joy in sessions with his reunited former band member Riku, and even receives offers from major labels to produce music for their art-ists. As things get busier for Kiyosumi, Ushio feels distant from him, and leaves without a word. Kiyosumi loses himself and becomes like an overused songwriting robot, and once again re-treats into his shell. Can’t stand watching him wrecked, Riku tries to get him out of the studio with the help of Ushio.
