A noble man in silk clothing appears in front of the fifteen year old Eun Hong, who is about to be sold off to the Courtesan house due to her father's debts.
He was the same man who occasionally bought the straw shoes that Eun Hong sold at the market.
After coming across him at the courtesan house, Eun Hong is sold off to him for a handsome sum of five hundred taels…

"Until you are able to fulfill five hundred tael's worth of work, you are my bride. Will you marry me?"
"I cannot do such a thing because I do not love you."
"I will give you 3 years. You can start paying back the five hundred taels after 3 years. Until then, all you need to do is pretend to be my bride."
"Pretend to be your bride?"

Choi Taewoong, the 21 year old leader of the Fire Dragon Trade business, the largest business in Joseon. He buys and sells everything with money, but will he be able to buy a bride with money as well?
