Hana's household consisted of a happy family of three: the daughter-in-law, her husband, and her father-in-law. However, unable to conceive a child, the wife began to carry a heavy burden. When she consulted her father-in-law, he too was at a loss for answers. Noticing that her husband had many siblings, she began to suspect that her father-in-law possessed strong sperm, and so she asked him to impregnate her. Initially, their encounters were purely transactional, but gradually, she became deeply drawn to the intimacy with her father-in-law, losing her heart to him. They had promised to end their affair once she became pregnant, and upon confirming the pregnancy, their secret relationship came to a close. Yet after the baby's birth, unable to resist their desire any longer, the two resumed their breeding sessions once again... This story unfolds into a profound exploration of desire, morality, and the complex nature of love within the family.
