Kanazawa Asa and her husband Tetsuya have entered their third year of marriage as "DINKs" (dual-income, no-kids). The couple agreed not to have children due to Asa's traumatic past, but the trust was cruelly betrayed when she found out that Tetsuya had secretly damaged the birth-control device and made her pregnant. Asa's life slowly turns into chaos with the unwanted pregnancy. At the same time, she finds out that an employee from the clinic she has been visiting is Tetsuya's junior from high school, who knew Tetsuya's past.
