Yoshikazu and Haruka. A young couple in their fourth year of marriage, but strangely they were not blessed with children. One day, when Haruka received a medical examination, it turned out that she was infertile due to congenital factors. The two, who were worried, confided the fact to Saori, the mother of her daughter-in-law. A kind mother who pains her heart with the ordeal given to her beloved daughter's womb. However, the young couple said to Saori with a transcendental serious look. "Oh, my mother-in-law, my daughter-in-law, instead of Haruka, can you please give birth to a baby?"
