The maid Duk Im meets the Crown Prince at the funeral of the late Royal Noble Consort Yeong, then learns of the banned book that she was warned that she would be killed if she read, and her anxiety increases when she learns that the book is in the Crown Prince's library.

San struggles to catch a rampaging tiger inside the palace, then unwittingly gets help from Duk Im, as he pretends not to be the Crown Prince in front of her. To prevent further casualties, this fierce tiger has to be stopped.

Duk Im seeks to help the maids escape from the tiger and is rescued by San, who almost receives punishment for mobilizing the army in the palace without the King's permission, while those who want to depose the Crown Prince try to exploit what happened to their benefit.

Duk Im is stunned when she discovers San's true identity. She is angry because she thinks he tricked her, but she is chosen to be his maid, while Princess Hwawan finds a way to set her up and punish her.

San saves Duk Im from a murder plot and finds out who was involved in it. Duk Im prepares to celebrate the coming-of-age ceremony for the court maids. However, the Queen does not make the day pleasant for neither San nor Duk Im.

San is still confined, and despite the long and tedious time he spends without books, Duk Im keeps him company, then volunteers to convince the Queen to help him.

Following the bathtub incident, San listens in on the conversation of the court maids and discovers something that brings him joy, while some symptoms appear on the King that indicate that he is not as healthy as he always was.

After the court maids are searched, a royal book turns up in Duk Im's belongings and she is suspected of stealing and interrogated. Hong Deok-ro defies the Crown Prince and recruits a royal doctor for the Dongdukhoe meeting for an unknown reason.

The King orders San to go visit the royal tomb, and then the ladies of Gwanghan Palace plan to get rid of him. Duk Im and Seo watch a number of gunpowder bags belonging to the East Palace being thrown into the river.

The King suspects San of planning treason for having the soldiers enter the Royal Temporary Palace when he was the one being attacked, while Duk Im tries to save Seo after learning that she was forced to join Gwanghan Palace.

The King gives orders that San be locked in his room, and Duk Im tries to help him get out of trouble. Then she discovers a secret document of a promise between the King and the late Crown Prince.

The King confesses that his current situation makes him no longer suitable for ruling the country, and he recalls the promise he made to his late son that he would make San the next king.

An attempt is made to kill San, but his royal guard saves him. He then discovers that his half-brother is involved in treason, while his love relationship with Duk Im suffers.

Wonbin suddenly dies at a young age, and Deok-ro must locate the court maids who suddenly disappeared. Meanwhile, Duk Im sets out alone to find her best friend, Kyung Hee, because she is also missing.

San orders Duk Im to get out of the palace. One year later, Deok-ro meets Duk Im and suggests that she run away with him. As San sees Duk Im by chance at Princess Cheongyeon's palace after a long time, he decides to leave the past behind.

Enraged by jealousy of Duk Im, Hwa frames her for having an affair with a man and makes Queen Dowager question her. Later, San makes his final decision about it.

For the sake of the country and their unborn child, Duk Im and San recover their strength. Close people around them die due to the plague and other events. However, San works hard to place the country on the road to peace.
