In a city somewhere in the northern Kanto region... Sumire, a pure housewife who has been married for three years, lives peacefully with her hardworking office employee husband. Sumire spends her days looking for a new home and previewing various properties in the city on weekends, partly because the rental apartment she signed when getting married has become a bit cramped. The sales agent of the real estate agency responsible for previewing properties has a bad feeling about such a beautiful married woman. One day, the agent could no longer stand the persistent viewings of a property, which is basically a closed room just for the two of them...!
