Kim Myung Soo is suspicious of even his own son.
On the 7th episode of tvN "The Three Musketeers" (script Song Jae Jung, director Kim Byung Soo) broadcast on September 28th, In Jo (played by Kim Myung Soo) is looking at the petition that Kim Ja Jeom (played by Park Young Soo) raised.
The pertinent documents were that there was a person on the inside that was talking with the Yong Gol Dae (played by Kim Sung Min). In Jo was all alone and started to imagine who was communicating internally with the Yong Gol Dae. Like that, they were standing all alone and going crazy as they started to even suspect Choi Myung Gil (played by Jun No Min).
In Jo said, "Choi Myung Gil? No he's honest. A right person would not be doing that" and shook his head.
Meanwhile, "The Three Musketeers" is a period drama set in the Joseon Dynasty. It follows the crown prince Sohyeon (played by Lee Jin Wook), his warriors Heo Seung Po and An Min Seo, and a man named Park Dal Hwyang who is preparing for his military examinations. Actor Lee Jin Wook is collaborating with director Kim Byung Soo and screenwriter Song Jae Jung.
