For some, this drama may have not lived up to all their expectations, but it certainly lived up to mine. And I love rewatching scenes from this drama. This drama is so good I am trying to force my family to watch it. It may be a little difficult since they don't like medical dramas though. First, I want to talk about what this story was to me and why I love it so much! This drama may have been played off as a medical drama, but, to me the medical stuff was only a backdrop for the real heartwarming story! This story was about a Romance that never died, even if Song Jae-Hee had died, I am convinced that Park Hoon would have never loved anyone his entire life. She was the only girl for him, and I loved that! I can't help it, a guy loving a girl no matter what whether she is dead or alive is my kryponite. This is why I loved this drama so much, the love spoke to me. To me, I can always get behind a romance if the guy is head over heels for a girl. The Heartbeat Couple withstood all the obstacles thrown in their way and got together. There were so many things trying to stop them from ending up together, other people who fell for Park Hoon, and also North and South Korean leaders. I heard that this drama was based on a book, and believe me I wish to read that book. Although, I heard that the ending wasn't as good for our Heartbeat couple as this ending was. Second, I wish to talk about the Cast/Acting. I loved it, all the actors played their parts well and I loved really believed that they were made for these parts. I can't really see any other actors playing these characters. Lee Jong Suk and Jin Se-Yun of course as our Heatbeat couple stand out! Also, just to let you know there are some really good kiss scenes in this drama! (I guess that is to be expected though, it is Lee Jong Suk after all.). Lastly, I want to talk about the music in this drama and the rewatch value. The music still brings tears to my eyes when I hear it because I can see the tragedy of our Heartbeat couple so clearly playing out before they got a happy ending. For the rewatch value, although, parts of this drama were clearly about medical operations and surgery, I would not rewatch those parts because I like my family am not into medical dramas. I prefer romance, friendship, action, and family over medical. But, I would rewatch the romance and the funny scenes. They were the core of this drama to me. Anyway, despite all the other reviews you read, I suggest you give this drama a try, because you might find that you love this drama like I did when everyone else gave it a bad review. I say it is well worth the time.
