The storyline is quite interesting but it is told in a boring way. I could say the same about the characters: they are well performed, but they are so boring. The female main character is one of the most boring ones I can remember. Honestly, I found this drama very disappointing. The first episode was pretty good and I was expecting a lot, but after that, it lost many of its interest. The best thing about it was its OST, which contains some nice tracks. I have read better reviews about other Gumiho dramas so, even though I haven't watched them, I would recommend them instead of this one.
