A girl named Rin Shima comes to a campsite in Motosuko, facing opposite Mount Fuji, to spend the day camping. While setting up a campfire, Rin notices a peculiar girl sleeping by the public restroom, but thinks nothing of it. Later on in the night, Rin once again comes across the girl, Nadeshiko Kagamihara, who had gotten herself lost after just moving to a new house, and shares her curry noodles with her before they both get a clear view of Mount Fuji. After eventually managing to get her sister to pick her up, Nadeshiko leaves Rin with her phone number in the hopes of camping with her once again. A few days later, Nadeshiko begins attending her new school, which Rin also attends.

Nadeshiko pays a visit to her school's Outdoor Activities Circle, consisting of two members; Aoi Inuyama and Chiaki Ohgaki. The girls attempt to put together a cheap tent only for it to break on them. They are helped out by Rin's friend Ena Saitou, who draws Nadeshiko's attention towards the fact Rin also attends her school. Later, as Rin goes on another solo camping trip, Nadeshiko, having been informed by Ena, goes over with some hotpot.

Nadeshiko tells the group what she expects them to be like in ten years when Rin returns. After bathing, the campers enjoy various movies and shows on a tablet Chiaki had brought along until they decide to call it a night. Under the stars, Rin and Nadeshiko talk about their plans for the new year before going to sleep. The next morning, the two cook breakfast and watch the Sun rise behind Mount Fuji. Rin returns to her job at a bookstore, while Nadeshiko continues pondering about getting one of her own to afford camping equipment. Ena texts her about a job opportunity delivering New Year's cards, which she accepts. In the epilogue, Nadeshiko returns to Motosuko to solo camp when she receives a message from Rin, who also happens to be doing the same. Nadeshiko proposes sending photos of their respective campsites to one another; after seeing herself in Rin's picture, she turns around and realizes they will be camping at the same location.

It’s approaching the end of the year. Rin plans a solo camping trip, while the Outdoors Club members earn cash to buy more gear.

It’s New Year’s Eve. Rin arrives at the shore in Shizuoka. Nadeshiko is busy with her temp job, when she receives a message from Rin.

Everyone is going to Izu to camp soon, and so Nadeshiko plans what to make. Meanwhile, Rin adds some new parts to her bike, when her grandpa pays her a visit.

Akari joins the other campers, and they head out to Izu. They check out various geospots and try the local food.

It’s the second day of the OutClub’s Izu trip. They go to Dougashima Island and walk across the tombolo, and put on a surprise birthday party for Nadeshko and Aoi at the end of the day.
