Now that she's re-learned how to ride a bike, Hiromi and Tomoe decide to go on a cycling tour of the city of Kamakura. They go sightseeing with Mori Shiki-sensei, who they run into on their tour, and Hiromi gets lost while practicing during a break.
The story begins with Hiromi Maiharu, a girl who moved from Nagasaki to Kamakura. She begins her new life in Kamakura and her first day in high school by bicycling to her school, but she has not ridden a bicycle since she was young. On the way to the ceremony for the first day, she meets Tomoe Akitsuki, and Tomoe helps her train to be better at bicycling.
