Actor Yoo Yeon Suk has joined the cast of The Writings of Nine Houses/The Gu Family Book! This actor was recently playing the bad guy in A Werewolf Boy with Song Joong Ki. He'll be playing Lee Seung Gi's rival and his character will be very skilled in martial arts, a top scholar, and just an all around perfect boy. I have never seen anything this actor has been in, but if he was acting alongside Song Joong Ki and now with Lee Seung Gi, then he must be good. Can't wait for this drama to come out the end of March/beginning of April. Little tidbit: this drama will be the first Historical drama for all three of our leads. Interesting, we'll see how they do!
