In the frozen duchy of Zentar, where blizzards bury travelers alive and darkness breeds in snowdrifts, a lone carriage arrives unannounced. Duke Millian Pastellio never expected a guest, let alone a fiancée bound to him by a contract devoid of warmth. Karina Leopold fled her family home without warning and journeyed to a land of eternal winter with one purpose: to say aloud what Millian has supposedly wanted since their first meeting.

But Karina isn't asking for freedom. She's asking for one year. Just twelve months under the roof of a man who has never loved her, in exchange for dissolving the engagement without scandal. Millian senses a trap, and his instincts don't lie — beneath her pallor and frailty hides not mere illness, but the "artistic malady." Those blessed with the ability to create miracles through brush, music, or thread pay with their own bodies, and for Karina, the price has reached its limit. She breathes life into her drawings, but every image she conjures devours her from within. The death sentence is already signed, and no cure exists. When Millian begins healing not her symptoms but her solitude, Karina catches herself entertaining a thought more terrifying than death itself: what if living is still worth it?
