Wife Ruriko (pseudonym) is a 27-year-old office worker with no children. Having been married for just nine months, she describes her family relationships as harmonious, especially cherishing her father. Influenced by this bond, she finds herself emotionally drawn only to older men and is inclined toward relationships with significant age gaps. Following this tendency, she chose an 18-years-older man with prior divorce experience as her husband. He works at a housing-related company, while she sells imported furniture. They met through model room work and had a whirlwind marriage just four months after dating. However, problems quickly surfaced after marriage, and she began struggling emotionally, saying, "I started worrying about the future..." This film portrays the inner turmoil, instability, and conflict of her newlywed life.
