As the school year comes to a close, third-year high school students prepare for graduation, including Mio Natsume, who grapples with unresolved emotions, Hazuki Morikawa, a member of the concert band, and Haruto Souma, a baseball fanatic. Meanwhile, Ena Komiya, a second-year student, works to revive the photography club to its former glory. Though the students have little connection, they cross paths with a new transfer student in his final high school semester. Eita Izumi's transfer is not unusual, given his frequent relocations due to his father's work. This time, however, he returns to his hometown for his last semester, rekindling old relationships and stirring up forgotten memories and emotions. As graduation looms, the arrival of Eita marks the end of carefree days and the beginning of a bittersweet final semester filled with new passions and challenges.
