Yi Heon, the king of Joseon has ordered the Prohibition of Marriage as he has not yet found a queen. However, the prohibition is already in its seventh year. Heon is not able to choose a queen as he cannot forget his beloved Crown Princess who passed away years ago. But then, a girl who claims she can be possessed by the late Crown Princess appears before Heon.

So Rang officially starts working at the palace as a court lady. Her duty is to make sure Heon eats well, sleeps well, and help him talk to Ja Yeon. Although she is nervous that Heon might think of her as a fraud, she still does her best to make him lift the marriage prohibition. Also, So Rang's past is revealed. She tries to avoid everyone who once knew her as her true self, Ye Hyun Sun.

Shin Won seems to realize that So Rang is Hyun Sun, but So Rang is not quite sure whether he knows or not. Meanwhile, Heon gets advice that it would be wise to go on a hunt. It is to show that Heon is still strong as always even without a queen. However, something unexpected happens at the hunting site and puts So Rang in need of a physician.

The absence of So Rang leaves Heon more bored than he expected. As she comes back after full recovery, she runs into a book writer at Aedaldang. Do Seok is a writer and painter who makes romance novels. With the masterpieces he made, So Rang tries to provoke Heon to wed a girl. Meanwhile, Lady Seo gets word that someone who resembles Hyun Sun is in town. She looks for her herself to get rid of loose ends.

Even if it means defying the King, Shin Won cannot bear to see So Rang spend a night with Heon. Because of his feelings for her, the tension between Shin Won and Heon grows. Meanwhile, a rumor spreads across Hanyang that the ghost of the late Crown Princess is witnessed. Shin Won and So Rang are in search of the person who started such chaos.
