ギヴン, 被赠与的未来

Mafuyu Satou, clutching his Gibson guitar tightly, exits his dark apartment to begin a new day at school. During a break in the gymnasium, he encounters Ritsuka Uenoyama who scolds him for letting the strings of his guitar rust and snap. Impressed by Uenoyamas knowledge of the instrument, Satou pleads with him to fix it and teach him how to play. Eventually, Uenoyama agrees and invites him to join a jam session with his bandmates: bassist Haruki Nakayama and drummer Akihiko Kaji. Satous voice is strikingly beautiful, which inspires Uenoyama to make him the lead singer of their band. Although hesitant at first, Satou accepts the offer after an emotional reunion with a childhood friend. With his new friends by his side, Satou must learn not only how to play guitar but also confront the enigmatic circumstances surrounding its ownership.
