The ronin's son, Hidetoshi, is a mother's boy who is kind and has a feeling for his family-minded mother, Kaori. One day, Kaori went out unusually, so when I was wondering, he went to the gym. However, Hidetoshi suspects Kaori when he sees him making a phone call, and when he secretly follows him, he witnesses Kaori disappearing into the house of a young man. "Mother's liar!" And Hidetoshi involuntarily pushes down Kaori who tries to go out again without knowing anything.
