A diligent professional woman who remained unmarried throughout her life passed away in a pitiful condition, leaving behind no family or loved ones. Her niece, Yamaguchi Narumi (35 years old and single), was deeply affected by this news and decided to abandon the search for marriage in favor of preparing for her own death. She believed that the only way to die peacefully without causing any trouble would be to live a solitary life like her aunt had done.
