In the first episode that aired on September 10, Han Jung Soo played Secretary Go, who follows Joo Hong Bin (played by Lee Dong Wook). He follows the orders of Joo Hong Bin, who is a hot-tempered foul-mouthed CEO of a game company.
Despite the anger management issues of his boss, Secretary Go is loyal. Han Jung Soo portrayed this character very well. Despite his deep voice and masculine appearance, his comical behavior matched well with his profile. In a scene where Lee Dong Wook threw clothes at him, he was quickly able to catch all of them. And when Lee Dong Wook got furious, Han Jung Soo was able to lift him up and run down a busy street. There was even a cute scene where he got annoyed because he found out that the driver, who he lives with, secretly took some of his essence.
Even though he has his comical and cute characteristics, Secretary Go is also a character that Joo Hong Bin is able to rely on. Since Joo Hong Bin is in conflict with his father, Secretary Go is the one that takes care of him. Much anticipation is given to how Han Jung Soo will be able to portray this character with contrasting qualities.
Meanwhile, “Iron Man” is about a man, Joo Hong Bin, who is able to sprout knives out of his back when he gets furious. He soon changes as he falls in love with the warm-hearted Son Se Dong (portrayed by Shin Se Kyung). It airs every Wednesday and Thursday on KBS.
