A professional of hospitality heals your exhausted heart.
Pushed to your physical and mental limits by consecutive days of overtime, you flee to a late-night health spa. The steam-filled facility is hushed and still, serving as your sole sanctuary to soothe your weary body. Yui Ichinose, who works there as a "Sauna Lady," quickly senses that something is wrong with you, one of her regulars. Her devoted care, which goes far beyond any manual, begins to melt your frozen heart bit by bit. However, the sharp gaze of Saeko Takagi, a manager strict about discipline, lingers in the background. Treading carefully to avoid notice, your secret time together begins now.
