Kazuma Hoshino is prepared for a new chapter in his life as an adolescent. Because of his brother Ayumu's poor health, their parents decided it was best for the family to relocate from the city to a more rural setting. The two brothers are now on their way to the Yorozuyo Inn, where they will remain until their parents can settle their business in the city and set up their new house. Their arrival to the inn, however, does not go as planned when they take the wrong bus and end up in the middle of nowhere, Ayumu has his hat stolen by a wild monkey, and Kazuma becomes lost in the woods while attempting to hunt the animal down. Everything culminates in a fortuitous meeting.
