As another school year begins drawing to a close, the third-year high school students move steadily toward the next milestone of their lives: graduation. Among them are Mio Natsume, a girl burdened with lingering feelings; Hazuki Morikawa, a member of the concert band but distant from the others; and Haruto Souma, an athlete obsessed with baseball. Meanwhile, second-year student Ena Komiya seeks to revive the photography club to its former glory, refusing to let the organization be disbanded. Though this group lacks a strong connection with one another, their lives suddenly cross paths with the arrival of a third-year transfer student.
