It is the same scriptwriter, so the style is similar though the story is very different. There is more romance, and drama, but there is the same feel of "very character driven" and the importance of communication.
The team behind those 2 dramas is almost the same, and you can feel it in the atmosphere, writing and direction !
Another drama about a young women learning to be a nurse, and growing through the people she meet through her work.
From the same writer, the balance of romance/comedy and thriller is really good. And the criminals are very interesting in both of those dramas.
Six Flying Dragons tells the journey of Yi Bang Won, the future King Tae Jong, and can serves as a prequel to Deep Rooted Tree. Beautifully shot, well acted, one of the best sageuk.
