To make a Drama based on a bad Movie (which itself was already based on a book) which got 27% on Rotten tomatoes, 5.4 on IMDB and 42% on Metacritic, and expect it to be successful is really daring, well, they tried.

I have read the book (In French) and seen the movie (disaster), still, Jang Geun Suk is the only reason I decided to watch this drama and boy oh boy do I regret it.
The actors did a great job (they carried me through the drama) with the weal plot/story they had, and I found myself caring for Bo Tong and Ma Te more than I really should have. Would I re-watch this again? No chance as a whole but there are some scenes I enjoyed and would not mind taking a peek at once more.
