5 years married. Not blessed with children, the Shiraki couple's activities were decreasing day by day. One day, Yuko decided to take care of her son Takafumi while her neighbor's couple went on an overseas trip. Yuko, who has loved Takafumi since she was young, thought she would entertain her with a luxurious dinner, but she is not feeling well at all. Therefore, the three decided to play hide-and-seek to encourage Takafumi. In order to hide from her husband who became her demon, Yuko invites Takafumi and hides in a dark closet.
