The Makoto couple's neighboring apartment was moved into by his mother-in-law. Since his father-in-law passed away, the wife had been worried about her mother who always looked lonely, so they discussed and decided on this. After that, they occasionally had dinner together and got along well. One day, when the wife went out with a friend, Makoto was left alone with his mother-in-law. He accidentally found her sex toys. 'You saw it, huh...' said the mother-in-law to Makoto.
