1819, Seoul. It's a dark, chilly evening, and the narrow, cobblestone streets of the city are lit only by the flickering flames of torches.

The air is scented with the aroma of cooking food and the sound of laughter and conversation from taverns and homes.

Suddenly, there's a commotion outside. The sound of music and laughter draws you to the window, and what you see shocks and enthralls you - It's a young man, dressed in flowing robes, drawing all the eyes of the town to him.
