While watching the drama I continuously asked myself: When will the awesomeness of that drama find his ending?! I already got hooked up after the first episode, and I never got dissapointed of a single one, which I think is a huge achievement for 20 episodes. I laughed, cried or just got hyper, even only because of the music they chose. And the best thing is: the end isn't predictable. So in all I would say you just can't go wrong with watching this drama :)
