Four members of the light music club active as Re:Sound.
About
High schoolers Hina, Yuma, Mahiro, and Kotono are members of the band "Re:Sound," formed within their school's light music club. As a popular quartet known both inside and outside of school, they spend their youth through music—after-school practices, live shows, and school festivals. The band's name carries their shared wish: "May the sounds we play together resonate in someone's heart, time and time again." Among the four, Yuma harbors secret feelings for Hina. Mahiro and Kotono, who have heard Yuma's romantic troubles, are well aware of his feelings. Since they both cherish Hina as a dear friend, they secretly root for the two, thinking, "They should just start dating already." Music, friendship, and romance—. In the irreplaceable time spent as a group of four, the relationship between Yuma and Hina begins to change little by little.
