I watched this drama simply because the story plot intrigues me, and also I wanna see Lee Hongki's acting. If your reason is as same as #1, you won't be disappointed. But if your reason is #2, well... just don't expect too much :( This drama story plot is quite neat, since every 'problems' presented here come to a conclusion in the end. Even my recent favorite drama, You Who Came From The Stars, has so many loops and holes in its plot. What I really like about this drama is how complex every characters are. Everyone has their own motives / point of views, so not everything is pure black or white, something I value the most in k-dramaland because it always makes things more interesting. However, one of the most substantial flaw in this drama is lack of chemistry between the main characters! I get easily bored when watching this drama I don't even know why :( Too bad because I'm really enjoying the story, but it took me so long to finally finish it! Overall, if you're looking for a drama with good story plot with a little bit of ghost story, this drama might be suitable for you. But please be noted, this drama might bored you (or not) a little, from middle to the end. The good thing is, everyone has their conclusion in the end, so it's quite worth the patience. Sadly, this drama does not leave 'strong' impression that makes me want to rewatch again in the future.
