Yayoi Miyasaka from Chiba prefecture is 54 years old. The Miyasaka family, who has been married for 35 years, has three children with her husband who is a self-defense officer, and each of them is already married and has four grandchildren. It seems that it was good until last year when the house was rebuilt and the eldest daughter and her husband and grandchildren started living together, but the sound is so clear that it makes me wonder if the newly built house is defective. The self-defense officer's husband lives in a distant base and has been sexless for many years, and Yayoi is frustrated.
