Synopsis: A Contract Marriage Between Wealth and the Throne

The story centers on Sung Hee Joo (IU), a chaebol heiress from the Castle Group who has everything but "royal blood." Despite her wealth, her illegitimate status often makes her look down upon by the elite.

To secure her position and gain absolute social recognition, Hee Joo devises a daring plan: marry into the royal family. She then proposes a marriage contract to Grand Prince Yi An (Byeon Woo Seok).

Yi An is a prince with a high title but no political or financial power. Squeezed by the rigid palace rules and the strict supervision of the Queen Dowager, Yi An accepts Hee Joo's offer.

However, what begins as a cold business transaction slowly turns into a passionate yet dangerous romance amidst the intrigues of the struggle for the throne.
