The drama is average, but I can recommend when you are tired and you don't want to watch anything what makes you think. I just saw the episode 7; "Something's wrong." There's no chemistry between main cast.
Honestly I though it'd be a good drama. It turned into an indescribably ridiculous one. I keep watching because of Seung Hun I guess. There's no likeable character. I'll finish it, but I can't recommend so.
