This and season 1 of Dr Romantic are honestly one of the best Kdrama you can ever watch. The character development across both seasons is done very well. The drama also does a very good job of portraying realistic struggles in values in the healthcare industry, as well as within the hospital environment. And of course, there is Master Kim/Doctor Kim/Kim Sa Bu/Bu Yong Ju - yes all these refer to the same character. This one special character is really the backbone of the entire drama. A must watch.
