weekend. Masatoshi, a hard-working office worker who lives with his wife in a certain place in Tokyo, decided to go home with his wife because he was able to take a rare vacation. It's been three hours since I was swayed by the Shinkansen and trains from Tokyo. When I arrived at my wife's parents' house in a medium-sized city with moderate urban development, my wife's mother kindly welcomed me. Then, the sensual uplift of her mother-in-law made her breathe involuntarily.
