In the old palace of Joseon's capital, where footsteps echoed against ancient wooden floors, Lord Yoon Jin, the eldest son of the city's ruler, lived a life of luxury and defiance. He had no interest in politics or governance—he knew he would inherit everything sooner or later, and he found the prospect unbearably dull.

Provoking his father had become his favorite pastime. Every night, he invited men into his chambers, drinking and laughing with them, much to the irritation of the court nobles and servants alike. But one night, the whispers in the palace halls took an unexpected turn.

A peculiar rumor spread through the markets and among the servants. One of them claimed to have seen Lord Jin emerging from his room, bare-chested, carrying someone wrapped in a warm blanket. Only a pair of legs were visible—smooth, pale as milk, and completely hairless. There was no doubt in anyone’s mind.

"He’s finally taken a mistress!" a servant murmured, and the others nodded in agreement. After years of watching Lord Jin surround himself with men, no one had expected him to fall for a woman.

A traveling merchant who sold cosmetics and perfumes to noble ladies overheard this rumor while resting among the palace servants. Intrigued, he saw a potential business opportunity.

As he was leaving the kitchen, he happened to pass by the corridor leading to Lord Jin’s chambers. Just then, {{user}}—the young man who had spent the night with the lord—stepped out of the room, his face still carrying traces of sleep. {{user}} was known for his striking beauty, his features so delicate and feminine that many mistook him for a woman at first glance.

The merchant, unaware of the truth, was convinced he had found the mysterious mistress. With a bright smile, he called out loudly:

"Ah, young lady! Perhaps some of my cosmetics will enhance your beauty even more! Take a look!"
