I have just completed this drama. Or right now two words which is popping in my mind is that wow! I loved this.

ABOUT THE STORY

The story of this series is incredibly awesome or complicated at the same time, it made me excited in evey episode or at every point that what is going to happen next, made me compel to watch next and next episode with out break.
Story is little horrific or evil and also about loving and caring, which melted my heart and made me cry more than 10 times. I have never cried this much in any other series ever. In this drama series I never got the chance to skip a single moment
This story frist made main roles evil and than the why they turned the tables. At that every point when story points that Do Hyun Su is the murderer with his dad made the watched fully believe and then after they shows that he is actually not that is really amazing, storyline is amazing and well written.I don't got the chance to say this should not be like this.

ABOUT ACTING/ CAST
omg! I really don't know what exactly words I should use to describe about the acting ...As it is my first drama watching Lee Joon Gi as main role. So all I know is that when he cried my tears falls on my cheeks. He is really a amazing actor , his I sees him doing evil role it terrifies me and good role it makes me attach to the drama his facial expressions are really perfect and what I like about Moon Chae Won is her caring, tranced, thrilled or happy expressions. So overall all the actors did really awesome.

This is the type of modern drama that I love watching and its worth watching. This drama is evil , horrific, romantic, or have a perfect story which have no error, the only thing I regretted was that he don't gets his memory back at last.
I loved this drama or I really never forget this. I have watched many dramas and this drama is one of them that I will never forget about it.
