"Jung Do Jun" Kim Soo Young betrayed Yoo Dong Geun and put crown prince Wang Chang on the throne.
On the episode of KBS1TV "Jung Do Jun" broadcast on April 12th, Jung Do Jun (played by Jo Jae Hyun) put Lee Sung Kye (played by Yoo Dong Geun)'s family member Jung Chang on the throne after Woo Wang was banished from the throne.
However, Jo Min Joo argued that Lee Saek (played by Park Ji Yil) and the crown prince had to be banished from the throne. In the end, Chang Wang at the age of 9 went to the throne and Jo Min Soo got the actual authority.
At Jo Min Soo's betrayal, the Lee Sung Kye clan was angered. However, Jo Min Soo said, "I didn't change my position" and started an official conflict with Lee Sung Kye.
