Grey, an intern, is more life-oriented and talks about the life of a doctor. Of course, there are many interesting cases.
Private Clinic is a derivative drama of Grey, and its general style is similar to Grey's, except that the scene is changed from various city hospitals to Hollywood beach scenery, which makes it feel more lively.
These three plays are the main medical drama at present. I can't say which one is the best, it depends on my personal preference, but I have finished all Gray's plays, and I haven't finished the other two.
There is also the story of the old emergency room, the story of interns, the story of people in a foreign land.
There are also stories about cardiologists, nurses in charge, head nurses who want to go to sea and ask for advice.
