Second-year university students YASUO♂ and MAKOTO♀ are a couple living together at the same university. Although they are considering marriage, they face strong opposition from their parents. As a result, they decide to pursue a pregnancy marriage (dekichaku). Starting in July 2014, cameras documented their journey as they began a strict plan to achieve pregnancy. First, they identify the days when conception is most likely. Then, they engage in intense creampie sex only once per month. To ensure high-quality semen, they impose a harsh rule: complete abstinence from masturbation. For these young teens, cohabitation under such strict conditions is extremely challenging, but they endure for the sake of achieving a pregnancy marriage. In return, they make their once-a-month sex sessions incredibly passionate and fulfilling. They check results using pregnancy tests, but continue to receive negative (not pregnant) results. After nine long months of repeating this routine, they finally get a positive result. Will their pregnancy marriage come true?
