Cha Yang-Sun, a poor girl who embraced extraordinary dreams, lives in poverty. One day, her parents, burdened with nothing but debt, sell her to the Park merchants, rumored to treat their children and women worse than animals. Nervously, Yang-Sun enters the merchants' compound, where she meets the mysterious young master, Ki-Tae, whose heart races...

What could be more frightening than this? This is the story of the bubbly Cha Yang-Sun's tumultuous success!
