While Nadeshiko makes gyoza hotpot for Rin, Chiaki gets a job at a liquor store to fund the club. Enjoying the meal, Rin apologises for being cold towards Nadeshiko when she invited her to join the club and promises to camp again with her some time. After spending the night in her sister's car, Nadeshiko wakes up early to watch the sun rise over Mount Fuji.

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.

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.

Nadeshiko hears a complex lie about soba udon from Aoi, who also has her younger sister, Akari, in on it as well.

There are many Rin doppelgängers that fool Nadeshiko to the point where she needs to text the real one.
