Kotarou Azumi and Akane Mizuno became third year students at junior high school and are classmates for the first time. These two, along with fellow classmates, Chinatsu Nishio and Takumi Hira, relate to their peers through mutual understandings and feelings. As their final year at junior high school progresses, the group overcome their challenges to mature and become aware of changes in themselves.

With the school trip looming, the third-years are abuzz with dating gossip. Meanwhile, Kotarou is busy with his writing, and Akane is working on her running performance.

Akane's big track meet is coming up, but she's flustered by Chinatsu's confession to her that she has a crush on Kotarou.

Akane decides to apply to a school in Chiba that her parents and Takumi recommended. She meets with Kotaro, who says he will try to apply to the same one and that, regardless, they will be together. The track club later goes to Kotaro’s festival.

Kotaro learns that he was not accepted into Akane’s school, saddening them. Daisuke suggests Kotaro use it in his writing, while Ayane suggests Akane should break up with him rather than do long-distance.
