Mafuyu Satou leaves his dim apartment for another ordinary day of high school, Gibson guitar in hand. He dozes on a quiet gym staircase and runs into Ritsuka Uenoyama, a fellow student who scolds him for neglecting the instrument until its strings have rusted and snapped. Drawn in by Uenoyama’s know-how, Mafuyu asks him to repair it—and to teach him how to play—setting off a connection that leads Mafuyu to a jam session with bassist Haruki Nakayama and drummer Akihiko Kaji.

When Mafuyu finally sings, his unexpectedly beautiful voice pushes Uenoyama to see him as the band’s potential lead vocalist. Mafuyu hesitates, but after an emotional reunion with someone from his past, he begins to open up. With the band’s support, he works to learn the guitar while confronting the unclear, painful story behind how it came into his hands.
