[Machine Translation] When the defeated nation of Arnotes is offered peace terms by the enemy nation to "marry a saint," it offers its first princess, Sonia.... However, Sonia is a fake saint with no power who was only made to take the place of her sister, a real saint! Sonia, tormented by guilt, tells the truth to her husband, Charles, the brother of the enemy king, and asks him to forgive her country in exchange for her life, but he gently tells her that he has no intention of punishing his precious bride, even if she is not a saint. True to his words, no matter how long he waits, he is not executed, but rather cherished as a wife, and he finds himself living a happier life than when he was in Arnotes. Sonia is bewildered by her undeserved happiness, but after the arrival of the false saint Sonia, the enemy country somehow becomes wealthy, and Arnotes, on the contrary, begins to decline...?
