Having spent Christmas camping with her new friends, Rin Shima embarks on a solo-camping trip to see the New Year sunrise by the sea. All goes according to plan until unforeseen weather blocks the roads back home, making a return trip impossible. Rin, who is now stranded for a few days, is invited by Nadeshiko Kagamihara to stay at her grandmother's house.
What is supposed to be a two-day trip becomes an extended period of sightseeing and new experiences for Rin, and she encounters some new and old faces along the way.
