What is the happy ending of royal love in Princess in the Palace?

Your Princess Wan was finally sentenced to death by the Emperor and the Empress Dowager, because Wan's last behavior was revealed, which is also the reason why Highland and other concubines designed it. Highland did it just to avenge Ruyi.

Wan Fei in Ruyi Palace is a woman with a deep heart. She is just an ordinary little maid-in-waiting, and she has a boyfriend named Ling Che Yun. As a little maid-in-waiting, Wan was humiliated, while Ling was just an ordinary soldier, unable to shelter from the wind and rain. Therefore, Wei Yiwan chose to throw himself into the arms of the emperor.

After becoming a high-ranking imperial concubine, Wan became more and more obsessed with the scheming for favor, and pulled Ruyi off the stage by despicable means. Finally, Yi Ru was forced to use his own death to frame Wei Dianwan. After Yi Ru's death, the emperor did not attack Wei Yan, although he suspected that he was gentle. At this time, Wan was deeply rooted and had four children. It's hard to beat her.

In order to avenge her, Ruyi's good sister, Highland, secretly collected evidence and joined Wan Di to expose Wei's scandal in front of the emperor. The emperor interrogated Di Wei Wan's maid Chun Chan, who told Di Wei Wan all the bad things she had done. So the emperor and the empress dowager decided to put Wan to death.
