Jo Hyun Jae (49 Days) has joined the cast of Yong Pal, the upcoming medical series starring Joo Won and Kim Tae Hee. In the new series, he will play Kim Tae Hee's brother and Chae Jung Ahn's husband.

Longtime drama fans may recall that Jo Jae Hyun and Kim Tae Hee already worked together before in the 2004 series Nine Tailed Fox (Forbidden Love). 

Although they played lovers in that series, there won't be any romantic feelings this time around (we hope!), as the two will be playing half-siblings in Yong Pal

Jo Hyun Jae will play Han Do Jun, the chairman of Hanshin Group who is married to the outwardly innocent but inwardly conniving Lee Chae Young (Chae Jung Ahn). Kim Tae Hee plays Han Yeo Jin, his younger half-sister, whom he puts in a coma to gain control of the family company (because what else are K-drama half-siblings for if not to scheme against for control of the family company?). 

Once Yeo Jin wakes from her coma, she plots revenge against those who wronged her. Enter Joo Won as Kim Tae Hyun, a talented surgical resident who makes illegal house calls to wealthy clients in order to support his sick sister. The doctor who goes by the code name "Yong Pal" meets the secretive heiress at the hospital, and we'll just have to wait and see what happens from there!

The premise is certainly interesting, and the casting is excellent. What do you think of Jo Hyun Jae playing the villain? Are you excited for this series? 

Yong Pal will premiere on DramaFever on August 5, following the conclusion of Mask. You can sign up to receive new episode alerts HERE! While we wait, you can see Jo Hyun Jae in the heartbreaking series 49 Days:
