when i first started this drama ofter reading the descreption i was exited and honestly the first episodes lifted to my expectation , but then the series just became boring and rediculous due to the lack of chemestry between the two main leads and the fact that they made fool of the NIS agents that they made them look as if they were a bunch of children playing hide and seek , an other thing that i didn't like is that the main lead played by joo won was hopeless and really stupid , i know that it was supposed to be a comedy so there must be some misunderstandings and hilarious situation but sometimes it just feels pethatic instead of funny , however I won't deny that i had some good time watching this drama and especially at the begennig , i laughed so hard until my eyes were full of tears and i really enjoyed the very few action seens dispite it was supposed to be a spy drama so my advise is don't be fooled by the dicription , the drama is totally diffrent , if you want some light drama with some funny moment and no actual depth it's for you , but if you seek a story that keeps you on the edge and leaves a huge emotional impression , then i don't recommand it .
