After discovering that the man she had loved since middle school was already married, the protagonist Yua begins visiting a marriage consultation agency. The agency's matchmaker, Fujisaki, recommends that she participate in a particular boot camp. Once Yua joins the camp, Fujisaki's demeanor changes completely. Transformed into an extremely sadistic sharp-tongued advisor, he mercilessly exposes the reasons why each of the female participants has been unable to marry. The story follows Yua and the other women, each carrying their own baggage, as they take on a grueling marriage-hunting program in pursuit of a happy marriage. The camp's stated success rate is one hundred percent, and the program promises to make anyone capable of getting married. As the narrative progresses, a turbulent marriage party begins, only for anti-marriage-hunting saboteurs to infiltrate the event. The series also introduces the only male participant to appear at the dojo, whose arrival stirs up further chaos. The story tracks whether Yua will ultimately be able to secure the happiness she seeks, building toward a dramatic conclusion.
