Ayumi married a divorced man who is twice her age and has a child. She was living a happy married life, but there was one thing she was worried about. It's about her son-in-law Kodai. She is in a rebellious phase, has quit school, and is wandering around without a regular job. She felt that she had to do her best as her mother... A young and beautiful woman, who was closer to her father's age, came to her house, which had been unfeminine until now, and began intervening and preaching to her.
