Yuu Koito is a new student at Tohmi Higashi High School. However, she is still dealing with a confession from a male classmate from middle school – unable to reciprocate his feelings, she struggles to figure out an appropriate way to turn him down. When she meets the confident and esteemed second-year student council member Touko Nanami, she confides in her that she feels as if she is unable to fall in love with anyone. Touko helps her with turning down the confession, but then abruptly confesses that she herself is falling in love with Yuu.
Later, Touko unexpectedly asks Yuu, rather than her closest friend Sayaka Saeki, to be campaign manager for her student council presidential run. As the pair grow closer, Yuu learns that Touko's public persona as a naturally-talented, hardworking honors student conceals her deep-seated insecurities and fears of inadequacy. Feeling as if she is the only one who knows this hidden side of Touko, Yuu resolves to support her. With Yuu's help, Touko wins the election.
