A modern doctor transmigrates into the villainess Isabella, abandons the original host's arrogant nature, and insists on not divorcing her husband Sebastian—the dragon duke who is cursed, disabled, and trapped in shadows. She uses modern medical skills to heal his body and gentle warmth to soothe his wounds. The two move toward each other and redeem one another, fighting together against the Silver Wing Clan's revenge conspiracy, breaking the curse, quelling the war, and after enduring life-and-death bonds, finally staying together in happiness.
