Mr. Ariga, who got married when he was young. The husband is successful in real estate and has lived a life without any inconvenience for more than ten years, but on the contrary it seems to be the biggest problem. It's a very difficult problem to understand, but from her point of view, her overly peaceful daily life is a repetition of the same thing, and she feels more bored than she imagined, and is desperate for stimulation. In addition, he complained about his husband, saying, "It's not enough if it's just kindness...", and he is not satisfied with his night life. What is sex that such a frustrated married woman is fascinated by!
