My wife Misuzu and my husband, who wished for the happiness of her family, lived peacefully, but their only son Nin divorced because of sexlessness and returned home. One day, I was surprised at my underwear that I happened to find while cleaning my son’s room, but it crossed the line of parents and children in order to heal my son’s hurt heart. It started with a cunning relationship that put up with the voices of my mother and son.
