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.
