Shin Sung Rok affirmed that in the tvN Monday/Tuesday drama of "Liar Game" that ended on November 25th, he was an expert at acting in the role of a psychopath.
In the drama, Shin Sung Rok was a reality show host and producer, but his role spanned beyond that of an ordinarily show producer. As the show, "Liar Game" went on, he was able to understand exactly how viewers felt and had the supernatural power of controlling their feelings as well as the overall industry. With this, his character added tension to the plot week after week.
In particular, the character of Kang Do Young is a newly created role that has set itself apart from the original version of the piece, "Liar Game." Unless the original version, Shin Sung Rok was able to bring a significantly "Korean" aspect to the acting as his role was different to that of the original piece. Critics said that such helped to maintain the sharp sides of this character as Shin Sung Rok's sudden changes in expression and strong gestures added to the grotesque nature of the character and role. With this, Shin Sung Rok created numerous memorable scenes in the drama that will last in tvN drama history.
