Oh the comedy! I laughed so much while watching this, a total crack drama starting from the very beginning. There is not much romance bur even more comedy and action. Eric and million funny situations, he is good with those. The plot is very simple: take a looser guy throw in a few misunderstandings and he somehow becomes a special agent, everyone thinks he is genius but it's all just a misunderstanding. The basic elements are very similar to Super Rookie and it's hard to say which drama was better. The main female character in this drama was better at least! There are slow moments but overall the episodes pass swiftly and I rarely found myself bored, towards the end there is a bit angsting but all the comedy makes up for the boring moments. If you want to watch an Eric Mun drama I suggest this (or Super Rookie), forget about crappy Myung Wol The Spy.
