I can watch any genre if I feel the chemistry between the main characters. In this case, Oh my God, I can't feel anything!! Are they really acting? Why this guy always stands like he doesn't know where he is or what to do next or what's going on? And why this girl has always one expression in every her role? (I have seen 3 of them). When the script is not so good, the main thing is the leads! And what is going with NJH? He can't even kiss in this drama, think that he is the only one in this industry who has a girlfriend :) And one more thing-please, don't compare this drama to Goblin.the last one is still masterpiece in this genre!
The main thing in this drama is the chemistry between the leads. I wasn't surprised when I found out that they were actually dating in real life. And also it has a lot of life experiences and chances that we had to give each other. This was the first drama of Song Hye Kyo where I could see her really into the lead actor despite DOS in this drama she is great with the lead.
I loved every episode of this drama,especially OSTs, casting,main characters. Every single moment was beautifully shown. Love story and chemistry were amazing! I love first couple's romance,it was naturally and I felt they understood each other great. Second couple's romance was also great, otherwise it couldn't be, there is Lee Dong Wook. :) In this genre this is one of the most lovable and watchable drama and I advice everyone to watch this drama.
