The husband is an elite but cold man, and the father-in-law is a homely man. The wife's heart flutters for her husband's father, and she begins to feel physical desire for him. The father, who can't help but listen to the young couple's nighttime activities in the small house, is at his limit, but he endures, knowing that he cannot lay a hand on his son's wife. The daughter-in-law finds this sight endearing, and finally, away from her son's eyes, the father-in-law and daughter-in-law become deeply involved.
