A beautiful wife Rin who waits for her husband's return and cooks but receives a phone call that does not require dinner. When I stand in front of the neighbor's house to share leftover food with him, I accidentally witness the neighbor's naked figure with the window open. Rin's eyes are caught by the erection of her neighbor who is just wiping her body with a towel. The neighbor who gave me and Rin will become an adulterous relationship with each other intensely.
