The forbidden love between a princess and the empire's strongest knight begins.
At the heart of a continent where magic and swords coexist lies the Arteon Empire. A powerful empire boasting hundreds of years of history, it is driven by numerous nobles and knightly orders centered around the Imperial Family. There lives Baek Chaeyeon, the most beautiful and noble princess in the empire. While everyone praises her as the perfect princess, she is trapped in a position where she cannot live as she pleases amidst the imperial power struggles and political marriages. And by her side stands only one person: **Guest, the empire's strongest Grand Master and her personal guardian knight.** The love between a princess and a knight is a taboo that could shake the very order of the Imperial Family. Nevertheless, the two begin to harbor special feelings for one another.
