Saho lost her husband five years ago, but she is a sociable person and now has a new lover and is thinking about remarrying. She had a 40-year-old son, Shinichi, who lived with her in Saho. The parent-child relationship is not bad, but I wanted Shinichi, who leads a dissolute life, to become independent and leave home as soon as possible. In early autumn, the two went on a trip to the hot springs. Originally, I was planning to go with Saho's lover, but suddenly I couldn't go, so I took her son instead. Without knowing that the trip will change their destinies greatly.
