Mahjong is played on the second floor of a dimly lit Japanese house on a summer night. In the meantime, Natsumi, a beautiful wife who cares about the situation above, is downstairs. A gambling-crazy husband who has put his hands into all kinds of gambling throws in as much money as he can and loses, but his wife, Natsumi, manages to make ends meet with the minimum amount of money. However, after losing and losing at mahjong, the husband ran out of sticks, and as compensation, offered Natsumi's body, which had brought snacks, to the men.
