Hisayo, an elegant mother, is crazy about ceramics and attends a ceramics class in the neighborhood every week. The family is also peaceful and his only son, Masahiro, lives without any inconvenience. One day, Masahiro picked up his late mother at a ceramic art class. Then, my mother was covered with mud with a young man and was playing with each other in a scene that I had seen in a movie. "Well, my mother is like that ..." However, Masahiro wants to see which one is the true figure when Hisayo plays the same kind mother as usual at home.
