Hospital Playlist and Doctor Stranger are similar because both are Korean medical dramas centered on doctors and hospital life. Both series feature skilled medical professionals who face challenging cases, perform surgeries, and work under intense pressure in the hospital.

The two dramas also explore the doctors' personal lives, relationships, friendships, and emotional struggles alongside their medical careers. Both feature talented doctors with different personalities and backgrounds, creating strong character dynamics within the hospital setting.

While Hospital Playlist focuses more on the everyday lives, friendship, and teamwork of five doctors, Doctor Stranger has a more intense story involving medical competition, romance, mystery, and political conflict. However, both dramas share the same core medical setting and provide engaging stories about doctors, patients, hospitals, surgeries, and the challenges of saving lives.

For anyone who has an interest for Sado and Lee San that drama special is interesting as it covers a short period of teenager Lee San investigating his father’s story (Prince Sado). The 2007 Lee San is an epic journey covering his whole life with all the Palace intrigues and plottings.

On one side we have a fiction and another side s story that is a mix between historical events and fiction during Joseon. Rookie Historian seems to have been inspired by Lee San’s story as we know that this Prince had to fight for years to unveil the true about the unfair death of his father (Prince Sado) and was autraciyzed in the Palace for being the son of a traitor. In Lee San the Prince gets support by the painters bureau in Rookie Historian from the historians. Both had to be present in every event around the Palace to make records.
Rookie historian strongly advocates for equal opportunity for women and men, Lee San did it a little bit. Both are beautiful period pieces
