Maris, raised as a “substitute slave” in the Flare Empire embraced by the desert. Raised as the shadow of a noble daughter, bearing the fate of taking all suffering and punishment in her place, Maris is to be married as a false bride to the dreaded “Black Rose King” Kufu, rumored to “devour women.” Though trembling at the rumors, Maris steps into the palace as a noble lady. Yet, when she glimpses an unknown tenderness deep within Kufu's cold yet beautiful eyes, her heart begins to stir quietly... A marriage born of deception gradually transforms their destinies into an arabesque of true love.
