Five years have passed since I got married, which was the happiest time of my life. The current situation is far from the married life I envisioned at that time. After giving birth, her husband began to come home later and later, and she often spent time alone at night. And when half a year has passed since I stopped feeling the warmth of her skin, she has a smartphone on the tip of her extended finger and the two characters "adultery" on the screen... "Adventure named infidelity" begins for beautiful wife Sumire, who has reached her thirties and feels the danger of her as a woman.
