“It’s stuck deep inside me and I can’t get it out of my head. Mafuyu’s voice is an insane and dangerous weapon.” That day, I started to feel that playing the guitar and playing basketball, both of which I liked very much previously, was becoming boring. Uenoyama meets Mafuyu who’s holding onto a broken guitar. The moment Uenoyama finishes fixing the guitar, Mafuyu becomes completely attached to him. However, hearing Mafuyu’s song by chance leaves a deep impression on Uenoyama. An alternative love drawn by Kizu Natsuki!
