Episode 1

As night falls, a solemn atmosphere fills the Joseon-era castle.A group of assassins sneaked in quietly like ghosts, breaking the tranquility of the castle.At the same time, the imperial doctor Cui Shanglu was diagnosing the pulse of the empress dowager.What he felt was not only the physical discomfort of the Queen Mother, but also the undercurrent of crisis under the castle.

Inside the castle, the sound of clashing weapons pierced the tranquility.The assassins broke through the defenders and targeted the king.However, this sudden attack did not achieve the expected effect, and the king evacuated safely under the protection of everyone.However, this chaos brought unforeseen harm to Dr. Cui.He was seriously wounded in this battle and his fate was grim.

In another corner of the castle, the crown prince Li Jian quietly left his residence.He accidentally met a liar who claimed to be the exiled prince. Although this liar was full of lies, he unexpectedly triggered Li Jian's thinking about identity and responsibility.He saw through the liar's lies and handed him over to the police, but was accidentally injured during the fight.In order to cover up his injuries, he had to put on makeup, which foreshadowed his future actions.

When Li Jian returned to the castle, he faced his father's reproach and the queen's concern.He knew that his actions had aroused dissatisfaction and suspicion among everyone, but he stuck to his beliefs and secrets.At the same time, rumors about the prince began to spread in the castle.Some people rumored that the crown prince often sneaked out of the castle to have private meetings with a woman.These rumors not only caused the ministers to question the crown prince's ability, but some even began to propose that the crown prince's half-brother Daocheng should be replaced.

The Queen Mother was also dissatisfied with the Crown Prince's behavior. She believed that the Crown Prince went out frequently because he was addicted to sensual places.In order to save the crown prince's reputation and future, she proposed to let Cui Shanglu's daughter Choi Myung-yun be the crown prince's concubine.However, this proposal was rejected by Li Jian.He knows his true inner thoughts and pursuits and does not want to be restricted by worldly constraints.

Cui Mingyun is a unique woman. She inherited her father's medical talent and devoted herself to becoming a great doctor.She is eccentric and passionate, often treating the poor, and fearlessly confronting rebels and thugs who are many times stronger than her.She firmly believes that she belongs to the civilian world, and even though she lives in a castle, she always maintains a simple heart.

However, fate did not seem to favor this kind woman.An old sage's prophecy puts her in a difficult situation.The prophecy that she would bring disaster and death to her husband deeply worried Choi Sang-rok.He tried to persuade his daughter to give up her relationship with Li Jian, but Cui Mingyun firmly believed that her destiny was in her own hands.She decided not to marry Li Jian because she didn't want to be the woman who brought misfortune to her husband.

At the same time, another bizarre murder occurred in the castle.Li Jian found the body of a girl in the palace pond, but the autopsy results showed that it was suicide.However, this is already the second such case.Last year, a maid was found dead in the same place, and was also ruled a suicide by royal doctor Heo Jin-soo.These two cases did not seem simple, and Li Jian decided to investigate the matter personally.

As the investigation deepened, Li Jian gradually discovered some shocking truths.It turned out that the Queen Mother actually had an improper relationship with a palace doctor.And this secret seems to be inextricably linked to the two murder cases.Li Jian is determined to uncover the truth of all this and seek justice for those innocent souls.

However, as he sinks deeper and deeper, the danger gets closer and closer to him.A group of mysterious rebels began to hunt him, and their leader turned out to be a figure inextricably linked to Cui Shanglu.All this made Li Jian realize that he was in a huge conspiracy.He must remain vigilant to uncover the truth and protect himself and those around him.
