This show started off really well and the backstory/ set up was really promising. However, once it caught up to current times, the plot floundered. There was a real lack of story telling in this drama and I ended up pretty underwhelmed. The real saving grace of this show was the acting. Kim Rae Won and Park Shin Hye did a good job for the material they were given. There was some awkwardness in the beginning of the relationship, but then there was complete comfortableness and next to no drama. I wasn't a huge fan of Yoon Gyun Sang at first, but he grew on me through the run (but they definitely could have styled him better). Lee Sung Kyung was believable as a spoiled lonely rich girl. I enjoyed all the supporting characters save the doctor that played Seo Woo's father. He was so childish and immature that I found it hard to believe he was running a hospital. But the actor did a wonderful job of conveying the spirit of the character. He was immensely unlikable. There were lots of great cameos as well, and the most memorable was played by Nam Goong Min - his episodes were some of the better parts of the floundering middle. I wouldn't recommend this drama unless you are just a fan of the actors. There is not really a plot to it at all, and even as a hospital drama it was lacking. While it had a promising start, I only finished it because I was invested in seeing it to the end once I realized that the plot was never going to pick back up and that nothing was really happening to our main characters. All the action was happening around them instead.
