First, this drama is uncommon. The chemistry between the characters is incredible, we feel the strenght of theirs feelings. Then the story is interresting because it's funny to watch all this technology and the world of hackers. The must is the past story : illegal radio and close friends -> a very good mix. I liked also the fact that there is no bad guy, or rather a stereotype of the bad guy. There are bad people, but they have some reasons to act like they do. The psychology of the characters is very impressive and good used. Congratulations, this drama is a success.
