Rin Shima has left her hometown in Yamanashi to live on her own in Nagoya while working for a small publishing company there. On one winter’s weekend in the not-too-distant future, as she’s planning a bike tour, she unexpectedly receives a message from an old high school friend, Chiaki Oogaki, saying she’s currently in Nagoya. Chiaki now works for an organization promoting tourism in Yamanashi, and she’s in charge of a project to reopen a facility that was closed a few years ago. When Rin casually suggests that such a large property would make a good campground, Chiaki is inspired. She gathers up all of their old camping buddies— Nadeshiko Kagamihara, who works at an outdoor goods store in Tokyo; Aoi Inuyama, who’s now an elementary school teacher in their hometown of Yamanashi; and Ena Saitou, who works at a dog grooming salon in Yokohama—and the campground-opening project is set in motion. So the story of five outdoorsy girls who became friends thanks to their shared love of camping begins once more, taking on a new challenge with the knowledge and experience they’ve gained.
