Half a year ago, my wife and I had a quarrel over trivial matters, and as a result, my wife returned to her parents' house. After that, I lived a solitary life in a house that was a little too big for me to live alone. Maya Sawamura, a beautiful kimono-clad mother-in-law who came all the way from her hometown, came to visit me without any contact, probably because she was too tired to wake up in the morning.
