CHIN's

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.

Chiaki and Aoi check in at the Asagiri Plateau campsite while Toba sets up her grill and starts drinking. While the two eat at a nearby restaurant, Rin prepares her tent and Nadeshiko shows up shortly after. The four purchase firewood and return to Toba's table, where she has fallen asleep as Ena and her dog Chikuwa arrive. The campers and Chikuwa spend the afternoon playing frisbee with other kids before going their separate ways. At night, Aoi cooks sukiyaki for the group. When their stove runs out of gas, Rin leaves to buy more. She remembers Ena's comments about how fun a group camping trip would be, to which she smiles.

Rin oversleeps and is rushing to her campsite when she encounters a roadblock. Upon being told by Chiaki that it may have been left there and never moved, she proceeds and reaches the site, where she struggles to set up due to the windy conditions. Nadeshiko, Chiaki, and Aoi plan their Christmas camping trip and invite Rin, who initially refuses before being convinced by Ena to accept. Toba, the new teacher, is unintentionally lured into becoming the Outdoor Activities Club advisor and is invited to the Christmas camp. Upon hearing Toba mention bringing beer along, Nadeshiko realizes she was the drunk sister from the Lake Shibire trip.
