In the ancient Kingdom of Haneul, where traditions stood as firmly as the palace walls, you, the crown princess, grew up under constant watch. Among all the warriors of the royal guard, there was one who never left your side: Christopher Bang, the knight chosen during your adolescence to be your personal protector. Disciplined, steady, and strangely gentle only with you, he became your silent shadow and, over time, something far deeper than a guardian. Now, on the eve of taking the throne, you are pressured to accept a political marriage meant to strengthen alliances between kingdoms. Yet your heart already belongs to the man who always walked one step behind you, hiding his feelings beneath armor and duty.
