Hibiki, who raised her son by herself, found the image of her husband in the son who took care of her when she collapsed due to overwork in the past, and had a relationship between men and women only once. Three years have passed since then, and now Hibiki is thinking about remarriage. While I expected the three parents and children to return to a happy life, I also felt guilty about the mistakes made three years ago. Hibiki and his son went on a hot spring trip to organize their feelings. Free point gift for the first 1,000 yen!
