Facing the harsh reality of infertility, a young couple's life takes an unexpected turn. The daughter, who had always dreamed of a perfect life, continued trying to conceive after marriage, but pregnancy never came. Medical tests confirmed she was infertile—an overwhelming shock for the couple. After much anguish, they were forced to make a difficult decision. One night, the daughter and her husband approached Sumire, the mother, with solemn expressions. In their hands was the infertility diagnosis. Surprised and confused by the sudden revelation, Sumire listened as her daughter made an emotional plea: "Mother, please carry my child." Confronted with her beloved daughter's sorrow, Sumire could not refuse. A few days later, on Sumire's confirmed ovulation day, the moment arrived. With the daughter present, Sumire engaged in intercourse with her son-in-law. Though tense and awkward, the act succeeded—her son-in-law's semen was deposited deep inside Sumire's womb. Months passed, and within Sumire's body, the fetus steadily grew. Alongside it, a new feminine awakening stirred within her, nurturing the seed of a new life.
