Kim Rwe Wha felt blood ties to Suh Hyun Jin.
On the episode of MBC "King's Daughter, Soo Baek Hyang" (script Hwang Jin Young, director Lee Sang Yeop) broadcast on December 4th, Mang Gu (played by Kim Min Kyu), Ddol Dae (played by Kim Rwe Wha), Sul Nan (played by Suh Hyun Jin) ate together and showed a warm scene.
Sul Nan said it was this easy to be a princess and she had worried for nothing and bragged. Ddol tae said, "No. I definitely heard what Dae Woon (played by Sung Ji Roo) said. It's a waste to throw him away after one time use" and showed his doubt.
Ddol Dae's worries turned out to be reality. Sul Nan was caught being a fake Soo Baek Hyung and she was in a dangerous situation as she almost got caught by Eul Min (played by Jung Yi Gap).
Mang Gu and Ddol Dae used a bird of Baek Jae to deliver this message. Afterwards, Ddol Dae sat and cried. He cried, "I always regretted sending my younger sibling Bo Kyung but never Sul Nan. If you do this again, I won't let you be at all" and cried out.
Mang Gu's older brother said it'd be okay and comforted her as this made people feel a bit pitiful.
Meanwhile, "King's Daughter" is a period drama drawing on the daughter of Baek Jae King Moo Ryung, the ups and downs of the story of the Baek Jae dynasty and their dire love story.
