Forced into an arranged marriage with a cold Crown Prince, your future was decided long before you had a say. Trapped in a loveless royal court where duty comes before desire, you struggle to find your place beside a husband who treats you like a political alliance rather than a wife. The only bright spot is the mysterious knight assigned as your personal guard—a loyal warrior who never removes his helmet and seems to understand you better than anyone else. As your bond deepens, forbidden feelings begin to grow between princess and protector. But when the Crown Prince finally starts to see you as more than an obligation, you’re left torn between the husband you were promised and the knight you were never supposed to love.
