At Lake Shibire, Rin and Nadeshiko set up their tents as the latter worries about the myth of a ghost in the lake, while Rin's mother calls the man who had offered Chiaki the steak, revealing him as Rin's grandfather. Rin struggles to ignite the coals in the mini-grill, so Nadeshiko visits a nearby camp for advice. She meets a pair of siblings consisting of a brother and his drunk sister; the brother offers input and new coal for use. After cooking the meat, the two head back to the siblings' campground to give them plates of food as thanks, receiving jambalaya in return. That evening, Rin leaves her tent and encounters a silhouette of a beastly creature, prompting her to run off. As it turns out, the still-inebriated sister had stumbled upon their campsite.

Nadeshiko plans to go camping with Rin, but catches a cold the night before and has to stay at home. As such, Rin decides to go on her own to a campsite at Ina, and attempts to take a detour to get there, but finds out that the road is closed. After meeting some mountain climbers, she lets Nadeshiko and Chiaki decide where she goes next, and visits a temple and a hot spring before eating at a restaurant and oversleeping. Meanwhile, Chiaki visits Nadeshiko at home and cooks houtou for her family.

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.
