After marrying her husband, Masayuki, Suzu discovered that he was an extreme mama's boy. She spent her days being bullied by her mother-in-law, Keiko, who would nitpick everything, including the taste of her cooking. The only source of comfort for her was her father-in-law, Shigeru, who cared for her, worried about her, and treated her with kindness. Before she knew it, Suzu began to feel attracted to her gentle father-in-law more than her own husband. Then one day, her husband and mother-in-law went away on a trip. In the large house, they were alone together, and she knew that her father-in-law was also lonely and isolated. The daughter-in-law and father-in-law gazed at each other in deep thought... and without thinking, Suzu was the one to seek a passionate kiss...
