Midori Saejima is a first-year student at the newly established Hijiri Gakuen. Midori is persuaded by her classmates to run for student council. Midori is reluctant but realizes that Akira Sudou is also running for student council, she becomes eager to win the election. Ever since Midori had seen Akira during the beginning of the school year, she had felt an intense attraction to him. Akira and Midori are elected president and vice-president respectively for the student council. Thus begins their story that centers on their relationship and the many adventures of high school with their friends.
Midori and Akira quickly become close, and Midori eagerly seeks the opportunity to become Akira's girlfriend. Although Akira seems to have similar feelings for Midori, Midori eventually finds out about Akira's feelings toward Hiroko, who is Midori's favorite art teacher at their school. Akira explains his past with Hiroko and how he considers her to be an important person in his life. Midori is somewhat comforted by Akira's honesty and his explanation that his relationship with Hiroko is strictly platonic. Akira eventually comes to reciprocate Midori's feelings.
However, their relationship is troubled by Midori's increasing jealousy toward Hiroko and Akira's strong connection. They break up after months of awkwardness. Midori finds comfort in her long-time friend Ken Nakagawa, who has secretly loved Midori for years.
