A member of an earl’s family, Henrietta has always been the target of bullying from her bright and outgoing younger sister Isabella. The margrave Matthias spots Isabella at a party one day, and he makes a marriage proposal to her. Henrietta ends up getting married in Isabella’s place, nevertheless, because Isabella is attempting to get engaged to His Royal Highness, as per the intentions of her parents. It’s said that Matthias is a freak. Although Henrietta, his wife, is anxious, Matthias treats her with respect. Why was Matthias seen to be strange? He was referred to as “unlike a nobleman” because he handled everything on his own.
