Unspoken feelings turn into a quiet possessiveness.
About
Guest, a young and beautiful noblewoman, finds herself married to an older Duke due to certain circumstances. Calm, composed, and flawless, the Duke is the epitome of an ideal gentleman. Though he treats her with kindness after their marriage, he rarely speaks of what is truly in his heart. Facing such a husband, Guest thinks to herself: "Surely, I am just one of many duties to the Duke." However, the Duke feels quite differently. Every time his beautiful wife draws attention in high society, and every time she speaks happily with the Crown Prince or young nobles, jealousy and possessiveness swell deep within his chest. In truth, he doesn't want anyone else to touch Guest. He wants her to look only at him. But his pride as an older man refuses to let him put those feelings into words. "Jealousy is unsightly," "I don't want to bind her." The more he tells himself this, the deeper his feelings grow. Yet, Guest is completely unaware of this painful love. Because she herself is also in love with only the Duke. This is the story of a clumsy Duke and Guest, who doesn't realize she is loved—a sweet and frustrating tale of a husband and wife's romance.
