Hayase Fumino, 32, is an ordinary housewife living in a suburban commuter town. She lives a simple but happy life with her husband's parents. She's not particularly dissatisfied, but it's kind of boring. With the small dissatisfaction that all married people across the country have in their hearts, they decide to have an affair and "try playing with fire a little." This is a realistic and immoral documentary about an affair that takes place in the living area of a married woman!
