In Part 2 of MBC's Friday-Saturday drama "Couple," which aired on the 20th, Yizhang County (Namgoong Min) helped Yoo Gil-chae (Ahn Eun-jin), who was caught as a Prisoner of war, escape. Yizhang County found Yu Gil-chae fleeing and stopped all arrows trying to catch him from a distance, including an arrow of keratinization (Lee Chung-ah) wearing a blue mask. Yizhang County immediately shot an arrow in front of the horse of keratinization, and Yu Gil-chae escaped safely from the arrow of keratinization. However, despite the help of Yizhang County, Yu Gil-chae couldn't get far and was caught by the barbarians again. Often this was taken back to the Prisoner of war market, and Yu Gil-chae was eventually taken to the royal palace. Gu Won-mu (played by Ji Seung-hyun) left for Shenyang to reclaim Yu Gil-chae, but he was shocked by the opposition that he had "already lost his integrity." Gu Won-mu nevertheless headed to the Prisoner of war market, but "already sold. I would have tasted a man. " Yu Gil-chae was sold back to the Prisoner of war market the day after Gu Won-mu left. Yu Gil - chae found Yizhang County in a distant footstep, but he could not face his face. Yu Gil - chae shed tears alone when he dreamed that Yizhang County was coming to rescue him. Yizhang County pushed out keratinization, but keratinization continued to grow in heart and required Yizhang County to serve dragonflies. Yizhang County said, "I can give you my body, but I can not give you my heart." keratinization said, "I am different from her." Yizhang County learned that Yu Gil-chae was being held as a Prisoner of war through Liang Yim (played by Kim Yoon-woo), who came to Shenyang the next day. Yizhang County appeared on the spot where Yu Gil-chae was sold as an auction the next day, and Yu Gil-chae said, "I keep seeing things." Yizhang County was also fixed on Yu Gil-chae. Yizhang County overpowered all the men gathered at the scene and headed to Yu Gil-chae, looking at Yu Gil-chae and shouting, "Why the hell?" The two avoided their gaze and shed tears, causing regret.
