Cha Hwa Yeon set a trap to find the real Kokureo spy.
On the episode of "The King's Daughter, Soo Baek Hyang" (script Hwang Jin Young, director Lee Sang Yeop) broadcast on December 18th, Do Rim (played by Cha Hwa Yeon), Myung Nong (played by Jo Hyun Jae), Dae Woon (played by Sung Ji Roo) came together at a place and had a secret talk.
Myung Nong carefully revealed that the person who was going to hurt Nae Sook (played by Jung Sung Mo) was the person that was close to him Yeon Bul Tae (played by Kim Byung Ok) and Jin Moo (played by Jun Tae Soo).
At this, Do Rim said that the person who reported Nae Sook was Princess Soo Baek Hyang and added a suspect, "Aren't you the person who started everything?"
Then, he said it was time to put down the trap and looked at Dae Woon. Do Rim also suspected Bi Moon people that Dae Woon had taught. Dae Woon was upset saying, "There's no way. They're like my children. There's no way."
Do Rim comforted Dae Woon proposing, "We don't know who it is so let's set a net first. Let's first make a rumor."
At this, there was a rumor that there is evidence that Nae Sook is not a Kokuryo spy and that he will be released soon, adding tension to the court.
Meanwhile, "The King's Daughter, Soo Baek Hyang" is a period drama on the life of Soo Baek Hyang, the daughter of the Baek Jae King Moo Ryung along with their tumultuous life story and their great love stories.
