Ch. 01 · The story

What it's about

Spoiler level: Minor — for the synopsis & review below

Princess Riette expects celebrations before her sister’s wedding, but an imperial envoy arrives with a threat instead: marry his cousin Kain and uncover his weaknesses, or her sister’s safety is at risk. The formidable grand duke resists her attempts to approach him, leaving Riette to propose a contract marriage. As their arrangement develops, the man known for his impenetrable reserve becomes unexpectedly attached to her. His changing behavior makes her question how much of their new intimacy is simply part of the bargain.

Ch. 02 · Our verdict

My take

The appeal is the sharp shift from Kain’s formal distance to unmistakable attachment, with Riette’s liveliness providing a useful counterweight. Korean comic reviews praise the artwork and the way his family warms to her, suggesting that the domestic material matters alongside the mature romance. The political coercion gives the opening urgency, but readers wanting a freely chosen courtship may find that foundation uncomfortable.

✓ Read it if…

Riette’s warmth changes the atmosphere around a man used to strict expectations. The pleasure comes from watching guarded reactions become personal ones, allowing small departures from etiquette to feel revealing even when the story also offers more explicit expressions of desire.

! Skip it if…

The marriage begins with a threat against Riette’s sister and an obligation to gather information about Kain. This entry uses the explicit Korean mature edition. RIDI also offers an edited version, and the currently listed comic run ends with a Season 1 afterword rather than a series finale.
