The real estate agent showed me a relatively expensive property that seemed to have something to say. In a situation that is very unconvincing for a young man who has moved to Tokyo from the countryside, Mirei, a big-breasted wife who lives next door, peeks out. A young man who was fascinated by her appearance at first sight simply signed a contract for an expensive property. A young man who has moved into a contracted property is immersed in the delusion of venting his desires while simply admiring every move of the beautiful wife Mirei who lives next door. One day, a young man witnesses a real estate agent having a friendly conversation with his wife. Even though he doubts the relationship between the two, he is still a young man who develops delusions.
