Story: The story for this drama was quite different to any other Korean drama I had watched, so it was really interesting. It pulled me in right away! I couldn't wait each week for the next episodes. At first the ghosts were a bit frightening... but then the ghost theme gradually became less noticeable, having more emphasis on the actual romance of the leads. There wasn't really a particular storyline (like with revenge...), but more just the storyline of why or why not the main leads can be together (which was kinda all determined by the ghost seeing power). Overall it was still veryyyyyy interesting to watch! Acting/Cast: The cast for this drama acted great! There was great chemistry between the main leads and the secondary leads. I realllllly liked So Ji Sub's character and Gong Hyo Jin's character. They both changed drastically through the duration of the drama. Gong Shil went from a clingy, whiney girl to a mature, independent woman. Joong Won went from a heartless, money hungry man to a devoted, loving man. I loved seeing their characters change. Music: This drama had realllllly good music. I even listen to it now just in my normal playlist. It helped to create the emotions and set the scenes better. Whenever I hear the songs again from the OST, they bring back happy, sad, funny moments from the drama... and makes me want to watch it all over again. Rewatch? Definitely! It has not a boring moment during the whole drama. I could watch it all again and still feel as good as I did the first time I watched it. I secretly wish it went for longer so I could watch the lead character's chemistry for longer. Overall: If you haven't already watched it... watch it! It is really interesting! You won't be disappointed... I hope. It is already very popular and highly rated, so it is worth a go.
