Mikuru works at a women's esthetic salon and is deeply passionate about beauty, regularly attending study sessions with colleagues to stay updated on the latest techniques and knowledge. At one such meeting, a fellow professional asks her to help out at a men's esthetic spa. Initially shocked at the idea of working with male clients and hesitant to accept, she reluctantly agrees after persistent requests. To her surprise, she finds joy in seeing how the male customers respond to her massages. Before long, she begins working at the men's spa two days a week, her latent sadistic side gradually awakening and driving her toward increasingly intense experiences. Through this journey, Mikuru discovers new aspects of her own allure and undergoes personal growth.
