It's been 20 years since I got married. Her husband has been working alone for five years, and she loves her son Hideyuki and living together. One day, because of the loneliness of her husband's absence, she had a flirtation with love, but she was seen in Hideyuki. Hideyuki, who saw love not as her mother but as a woman, could not hide the shock and beat that feeling. The love that made my son happy had a forbidden relationship.
