Although many girls seek attention from boys, Futaba Yoshioka has different aspirations. During her middle school years, she garnered plenty of male admirers, but this led to her isolation from her female peers. Determined to change her image in high school, she adopts an unfeminine and aloof persona towards boys, which helps her form new friendships in the process.
Unbeknownst to Futaba, her life is about to undergo another profound transformation with the unexpected return of her first love, Kou Mabuchi. He had disappeared suddenly during their middle school years, but the cherished memories they once created together still occupy her thoughts, and she yearns to recapture those moments. However, she soon realizes that the sweet and gentle boy from the past has entirely disappeared, replaced by someone distant and pessimistic. Though he acknowledges their mutual feelings from their shared past, he cautions that they can never return to those days, as everything, including himself, has been altered.
