She is a notorious womanizer wanted by the authorities, but in truth she is a magistrate who serves the people and the greatest detective under heaven. He is a powerful Third Prince who, while investigating a murder, is forced to lower himself, disguise himself as a woman, and pose as a delicate young lady before falling into the hands of human traffickers. She, too, is investigating a case, and disguises herself as a man to infiltrate the black market. At an auction, fate brings them together, and she takes one look at him on the raised platform, under the candlelight, caged and crouched on the ground, looking utterly pitiful. She spends a fortune to buy him. When he’s wearing makeup and a smoky skirt, she often calls for him in the tone of someone summoning a good-for-nothing. Every time, he answers with a smiling face, all the while swearing to himself that he’ll cut this woman into eight pieces! But when he removes his makeup and dons his crown, he only has to crook a finger, and she comes running over in a flash, blinking her big eyes and asking sweetly, “Your Highness, what can I do for you?” In an instant she turns into a little girl, sweet-talking and pestering him until she softens that cold, hardened heart of his… The prince thinks this woman might actually be… not bad?
