Saki, the young and beautiful proprietress of a traditional hot spring inn, once ran one of the most prestigious lodges in town. Now facing decline, she seeks advice from Kitashita, a powerful travel agency executive. He proposes a bold plan: leverage her beauty and charm to satisfy male guests, aiming for five-star reviews and restoring the inn's former glory. Though shocked, Saki agrees, having no other options. Introduced to influential local clients through Kitashita, she dedicates herself to exceptional service, believing their satisfaction is directly tied to the inn's survival. Proud of her high-class hospitality, Saki offers not just comfort for the soul—but for the body as well. To revive her beloved inn, this gorgeous young madam begins offering intimate, erotic hospitality. This is the beginning of a steamy innkeeper's tale.
