Yuko Anri is 54 years old and a full-time housewife living in Seijo. She has finally reached the 30th year of her marriage, her husband worked until retirement, and her children have found jobs and gotten married, so everything is going smoothly. She was supposed to pursue her own happiness, but as soon as her husband quit his job, he became like an empty shell and became self-indulgent. Yuko says that she no longer thinks of him as a man, as it seems like she has more children than a husband. The physical contact they once had in the bedroom has also disappeared, and all she has is free time alone... This is the arrival of a superbly mature wife who is enjoying the life of a woman to the fullest, and it's not over yet!!
