Shiori returned home using consecutive holidays for her father-in-law who lives alone after her mother-in-law passed away. However, the reunion with my father-in-law who I met after a long time was subtle. That should be it, once my father-in-law and Shiori had a physical relationship from loneliness. Even though it was a one-time mistake, it can't be easily forgotten... I can't treat my husband as usual, and my relationship with my husband becomes awkward. One night, my husband went out for a drink and my father-in-law was alone with my father-in-law for dinner.
