What is the plot of "Palace"?

Plot introduction:

"Palace" is adapted from the comic book of the same name. It is a youth idol drama with fictional scenes. It tells us a modern story about the marriage between a prince and a commoner under the monarchy system.

As the emperor's condition became more and more serious, Crown Prince Li Xin promised the Queen Mother that he would marry the girl who had already made an engagement as soon as possible. At this time, Prince Li Xin was only a high school student. He understood that as the crown prince, with this special status, he did not have the right to choose personal preferences.

In the end, her sense of responsibility as the eldest daughter and the family's difficulties made her reluctantly accept the marriage.

Crown Prince Hyoyeol died in a car accident 14 years ago. His son Li Lu was ordered by his mother to return to the palace to fight for the throne that originally belonged to him. With the return of Ritsu, who also had the right to inherit the throne, the originally peaceful palace was stirred up. Everyone, including the Queen Mother and the Emperor, believed that the simple Lu would not have any ambitions for power or the throne, and were very enthusiastic about his visit.
