Himori agrees to cosign a friend’s debt, only for the friend to disappear and leave him responsible for everything. With debt collectors making his life impossible, he flees to a rural hot-spring inn. There he meets Kiho, a lonely married woman, and their growing attraction soon lands them in bed together. Sharing the same loneliness, they fuck each other in a sweaty frenzy and enjoy a fleeting affair capped with a creampie—but their time together comes to a sudden end.
