The theme is "holding back your voice"... I am an office worker who has been living a peaceful life with my wife for five years. One day, I hit it off with a man named Ikeda, a craftsman who was dispatched to do exterior wall work on our house, and we decided to have a drink at my house. My wife is a full-time housewife and her shoulders and back get tired easily, so Ikeda, a craftsman who smells of alcohol, decided to give her a massage "right behind the sofa where I sit"... An NTR drama where you have to hold back your voice, focusing on "blind spots" throughout the entire story!
