"Good Doctor" Kim Min Seo discovers Kim Chang Wan's secret.

September 17, an episode of the KBS drama "Good Doctor" featured Yoo Chae Kyung (Kim Min Seo) falling into shock after learning the secret about Director Jung (Kim Chang Wan).

During this episode, Director Jung's constant pressure on Lee Yeo Won (Na Young Hee) and Choi Woo Suk (Cheon Ho Jin) continues, so that he could take over the Sung Won University Hospital.

Choi Woo Suk tells Kim Do Han (Joo Sang Wook) that Director Jung had done many things to try to take over the hospital 15 years ago as well. He stated that as a result, the chairman of the board became sick with liver cancer.

Kim Do Han knew that Yoo Chae Kyung shook hands with Director Jung in order to get her father's hospital back from her stepmother. Kim Do Han scolds her for it but Yoo Chae Kyung refuses to change her mind.

Kim Do Han finally tells her, "You just shook hands with the man who led your father to his deathbed." Yoo Chae Kyung falls into deep regret and begins to cry.
