Despite struggling with infertility, the young couple never gave up hope. One night, the daughter approached her mother with a serious expression and pleaded, "Mother, please carry my child." Deeply moved by her daughter's words, the mother ultimately decided to fulfill her daughter's wish. A few days later, after confirming the mother's fertile window, the daughter and her husband began the intimate process. At first, tension and anxiety dominated, but gradually, emotional connection grew, and time after time, the son-in-law's seed was deposited deep inside his mother-in-law. Several months later, the embryo successfully implanted, and a child steadily began developing within the mother's womb. As the baby grew, profound changes also started unfolding within the mother's body.
