The Forbidden Marriage

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.

The appearance of Ja Yeon's ghost stirs up the palace. However, Shin Won and So Rang investigate thoroughly to prove to Heon that she is not real. Eventually, they find out that someone has stolen the late Princess' court dress. The ghost is a person who just resembles Ja Yeon and is part of a scheme made by someone with a high rank within the palace.

Heon and Shin Won quickly go after the kidnappers who took So Rang and Hae Young. Although they were able to find Hae Young, it seems So Rang has been taken somewhere else. Eventually, they find her well in a small village called Gongnyang Village. By seeing how the people here are living happily with loved ones, Heon realizes what he has been doing to the people of his country.

So Rang believes that Heon still confuses her as the late Crown Princess. Although her love for Heon is sincere, she does not want it unless Heon feels the same way for her. Just as Heon is trying to prove that he also truly loves her, an attack on the Palace occurs. Chun Seok and Shin Won become severely hurt by the attack and leave Heon in danger.

Shin Won leaves the palace and does not want to be found. Although Heon is sad to let his friend go, his relationship with So Rang becomes much deeper. However, Heon must now officially choose a queen and lift the Prohibition of Marriage. As So Rang does not want an official title, the two are not sure of what to do.

Heon finds out that So Rang is a fraud. Despite his love for her, he must banish her from the palace. However, assassins appear before her as soon as she gets banished and Shin Won is the only one who can save her. Meanwhile, the queen selection is currently the biggest issue in Joseon. Lady Seo does everything to make sure Hyun Hee gets selected.

Heon and So Rang reunite once again. During So Rang's absence, Heon realizes how much he desperately needs her in his life. Meanwhile, Shin Won captures the leader of the abduction ring. He interrogates the man and becomes one step closer to bringing Cho Sung Kyun down. As the end of the queen selection draws near, So Rang prepares to become who she is meant to be.

So Rang finally steps up and retakes her rightful name. Hyun Ho also takes her side after realizing that he has been deceived by Lady Seo. The Prohibition of Marriage is lifted, and Joseon has become a country where everyone can love freely again. With So Rang as his Queen, Heon devotes himself to ruling Joseon by truly loving the people.
