A young and beautiful bride wanted to have a happy marriage, have children, and build a normal, happy family... The bride lives with her father-in-law, who lost his wife and husband. Her husband is earnest and hardworking, but he's unsociable, cold, has no sexual desire, and they have no sex. He even confesses that he hates children, leaving the bride in despair and crying. Her father-in-law, on the other hand, is kind and loves children. They share the same blood type and birthday, but they're complete opposites. The bride, drawn to her father-in-law, harbors immoral thoughts of wanting a child with him. His father-in-law also secretly has feelings for her, and he catches her masturbating with her underwear. Having made up his mind, the bride seduces him and begins a relationship. Like a kite with a broken string, the two make love again and again, and eventually the bride becomes pregnant with his child.
