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.
