In the drama, Ji Chang Wook will be playing a bodyguard and former military soldier. He said about his numerous action scenes, "I ended up suffering from myalgia in my neck. This is a piece that helped me firmly decide in my heart that I will not do an action drama ever again. We're promoting the drama as bodyguard-action-genre, but I didn't see it that way. The relationships in the drama are entertaining."
He added, "The myalgia may have been because the weather was cold. I worked out incessantly. I practiced martial arts at an action school and also lifted weights to portray a manly role. This may be the hardest project I've been in."
'The K2', also starring Girls' Generation's YoonA, premieres September 23 at 8PM KST!
