After being banished from her witch clan due to a minor incident (or so she asserts), Roselyn establishes a public bathhouse—specifically, a men’s bathhouse—in the capital of the Empire. Aiming to both admire attractive men and utilize her potion-making abilities, Roselyn immerses herself in managing the bathhouse. One day, curious about the strange effects of the bath, the Magic Division Commander Michael Winterman pays her a visit. Following an unexpected incident that results in Roselyn sharing a night with Michael, he starts coming back repeatedly. Just as their relationship begins to intensify, Jibril from the desert arrives, searching for Roselyn. When Michael and Jibril confront each other at the bathhouse, tensions rise. The two men appear to be in some sort of competition over Roselyn… but what is truly happening?
