An arranged marriage between the crown prince and the heiress of a famous company. Everything was going smoothly--that was until a few days before the heiress was set to come back to Korea. She fell ill and was unable to make the trip back. Her father--not wanting to risk the king finding someone else for the prince--found a replacement for his daughter.
