Overnight, she married into the prince's manor. She knew he loved someone else, but still stubbornly went her own way. When she finally pulled herself together, the woman he had set his heart on at last spared him a glance, only to use him for her own ends. She loved him, but he loved someone else. A letter of divorce: perhaps fate was impossible to escape. The struggle for the throne was a road soaked in blood, and the way ahead was treacherous. I will keep you safe. When victory is won and your beloved is in your arms, I wonder if you will have forgotten me?
