The most puzzling thing about this slightly odd drama is that it’s not based on a manwha. It seems tailor-made to have been based on one of the melodramatic, romantic manwhas that are so often the rage in Korea and Japan. And yet it’s an original creation from screenwriter Kim Kyu Wan – to which all I can say is, you got grit, to break from the tailor-made drama template most screenwriters use in this way. Kim Kyu Wan tends to write problematic dramas with a lot of potential, like Cinderella’s Sister and Robber. Iron Man centers on Joo Hong Bin (Lee Dong Wook), the oddball CEO of a hugely successful game company (video games, not board games). A chance encounter with Son Se Dong, an aspiring game designer, and the unexpected appearance of a young son he didn’t know existed, turns Hong Bin’s world upside down.
