==This could have been one of the best dramas of this year but it wasn't, sadly!==

[spoiler] First of all, the plot was really good but, to me, this story should have been more sadly, dramatic and dark in order to function, when they add comedy to a very sad plot it just doesn't work.
The leads were good, not an extraordinary chemistry but good enough, I feel like L was overshadowed by Hye Sun cause she's a wonderful actrees and a top class being a rich bitch (lol) and L as Dan wasn't good tbh, such a waste because he's a really good actor... the other actors were good enough except for Lee Dong Gun, not to hate but his character wasn't relevant for me neither for the story, he was just a character to explain something they could explain easily with just a few scenes, and Yeon Seo wasn't even atracted to him so what is the point having an irrelevant character the whole serie? Also I think we needed to see more of Ru Na's background and life in order to understands why she was like that.
Directing was good (normal), sound mixing and sound edition also good, the soundtrack is maybe the best part of this drama. [/spoiler]

[spoiler] Overall: I feel like this would be way better if they shorter to only 12 episodes, too much unnecessary scenes and I love L but.. yeah, maybe another lead actor. [/spoiler]
My score: **7.8/10**
