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.

Everyone is going to Izu to camp soon, and so Nadeshiko plans what to make. Meanwhile, Rin adds some new parts to her bike, when her grandpa pays her a visit.
