While most girls desire popularity among boys, Futaba Yoshioka wants the exact opposite. After attracting many admirers back in middle school which resulted in her being shunned by her female classmates, she decided that high school will be her chance to revamp her image. Therefore, she starts acting unfeminine and indifferent to boys, allowing her to make some “friends” along the way.

Little does Futaba know, her life will take another drastic turn when her first love, Kou Mabuchi, returns after his sudden disappearance years ago in middle school. Despite his extended absence, the fond memories they shared together still linger in her mind, and she wishes to return to those days. But she realizes that the sweet, gentle boy of the past has completely vanished, and in his place stands someone cold and pessimistic. While he admits that her feelings for him back then were mutual, he warns that they can never go back to the past, as everything, including him, has changed.
