Yukami Makoto is the protagonist of the story, a teenage boy who loves nothing more than soaking in hot springs. During his 100th visit, he stumbles upon Miyama-kan, a cozy inn run by four stunning women named Tokura, Akino, Tsutsuji, and Mitomo. Little does he know that his presence will lead to an unexpected turn of events when he accidently robs Yuri, the goddess of the hot spring, of her divine abilities. As a result, he finds himself employed by the inn.
