This is the first ever medical drama that I have finished. I was not expecting anything but I ended up watching it in 2 days...

I don't really like watching surgeons doing things inside bodies and blood flowing and that kind of things but despite all that, I really enjoyed the drama. I can't compare it to the first season (because I haven't watched it) but the atmosphere that was created in the drama between all the workers at Doldam hospital is what makes it so enjoyable. Every characters interact with one another and it makes the drama more realistic, as you expect the same thing to happen in a real workplace.
There are many second characters and each one of them is developed and has a certain depth: Dr Shim Hye Jin, who first appears aloof, has a reason for it and finally fits in with everyone; Dr Bae Moon Jung has an interesting family background; even nurse Hyung Mi is not a simple extra.
What I liked the most was how the drama tackled issues that are relevant today in Korea: the place of women in the medical field, domestic violence, having to be in debt to pay for your education, etc. But it was done very subtly and well and did not take away from the main focus of the drama.
The romance was cute and not overwhelming, both couples had great chemistry.
Finally, I appreciated the consistency throughout the script: the patients did not miraculously disappear after they were treated (though I would have liked some mention of their departure for the most important ones) and we even got to know the reason behind Dr Bae Moon Jung's divorce that was briefly mentionned in the second episode.

If you are searching for a realistic medical drama (realistic in terms of working in a hospital, not in the procedures, I couldn't tell as I am no expert) with great relationships developed between all the characters, I recommend this one.
