Great drama, worth watching. I must admit in the first half I was very frustrated and annoyed, but the characters developed over time and it got better in the second half. That doesn't mean that the first couple of episodes weren't great. It just means that it was hard to watch. Teacher Kim was a jerk at the beginning. Even though his behavior made sense looking back, I refuse to believe there wasn't a better way to teach his juniors. I myself would have quit several times if I had to work with him. But I enjoyed that he wasn't portrayed as some super hero who can do no wrong. His character/personality was very difficult at the beginning, but he did grow too. There were many different emotions I felt watching this. I cried more often than I want to admit. It's very dramatic and sad with all the medical cases. Of course many people die in a hospital series. I enjoyed the romance, but that wasn't the main plot of the series. It's about politics and money and about how to live a life worth living, about your principles and believes. It's very touching and thought provoking not only for people who work in the medical field.
