The youngest princess マデレーネ, who had been oppressed since she was a child, was ordered by her half-brother, who was the crown prince, to marry an "upstart" viscount. The royal family married for money, and the viscount married for the title of duke. "As you know, we married only for the benefit of each other's family. I don't think you are my wife." "But compared to living in a palace, I am happy enough. I will do what I can." Before long, I came to know the situation of Alan, who was behind the political marriage.
