Plot
Midori Saejima is a first-year high school student at the newly established Hijiri Gakuen. She is persuaded by her classmates to run for student council, and she becomes eager to apply once she realizes that Akira Sudō, a mysterious boy to whom she is attracted, is also running for student council. Akira and Midori are elected president and vice-president respectively, along with Bunta Kōno, Yūko Mamiya, and Shūichi Takigawa as other officers.
Though Midori and Akira quickly develop a close relationship, Midori learns that he has been romantically attracted to Hiroko Maki, her favorite art teacher, since middle school. Akira reveals that while Hiroko remains an important person in his life, she is already romantically involved with his tutor, Masashi Sakamoto. Akira eventually reciprocates Midori's feelings and they begin dating. However, after Hiroko and Masashi break up, Midori suggests to Akira that they too should break up once she notices he is unable to prioritize her over Hiroko.
After their break-up, Midori begins dating Ken Nakagawa, a musician and friend from middle school, but she realizes she cannot love anyone but Akira and ends their relationship.
