Yulicia, the saintess of the Kingdom of Eufrande, has one duty: to receive the will of God, the "Divine Oracle." One day, God declares, "To save the world, you must have a child with the prince!" Yulicia, who also happens to like the prince, immediately proposes to him. However, he does not believe in the Oracle and flatly rejects her, saying, "If you can make me fall in love with you, not as a saintess but as a woman, then I will have a child with you." Stung by his challenge, Yulicia vows to make him fall hopelessly in love and regret ever turning her down. But for some reason, the prince suddenly begins showering her with overwhelming affection... "Wait, I was supposed to make him fall for me, so why is he being so sweet instead? His intense advances are escalating so fast... I cannot take this anymore!"
