Life

If you're looking for something similar to Doctor Prisoner, Life may be your next watch. They're both fast paced kdramas that keeps you on the edge, they both deal with corruption, they have smart male leads, just a spoon of romance and Life is also a medical drama.

The tension between the director and the ML is also incredibly similar to Yi-Je's and Min-Sik's relationship and the acting from every actor (Specially Lee Dong-Wook and Cho Seung-Woo) is outstanding. Just by watching the first episode this series keeps you on a chokehold and I really recommend it!

Not only do the shows have similar casts and the same writer, but the structure and quality of the shows are very similar. They're both massively exciting and explore disabilities and mental illness in a nuanced, emotional way. I adore both shows and I think if you enjoyed one, you will absolutely enjoy the other.

They are both dramas where characters are trying to rejuvenate a business that is failing in some way. Life is set in a hospital when the hospital is suddenly put under new management and AoN is set in an umbrella company for many different businesses and focuses on mergers and acquisitions.
Each has a rather clever male lead where it's hard to know what he's thinking. Life also has a very well acted antagonist who acts this way.

Doctor Lawyer, Yihan (a surgeon who becomes a lawyer) and Prosecutor Seokyoung want to reveal the truth of medical malpractices and negligence in Banseok Hospital. And, there's Jayden Lee with hidden agenda.

""Life" is about a medical drama that depicts the power struggles and human stories that take place within a university hospital.

Son Sukku looks like Jo Seung Woo (I had to. But it is more than appearances). Both are Gu 'sajangs' with that kind of personality.
The dramas slow vibe, music, directing, etc.
The romantic relationship in My Liberation Notes, and a similar one in Life only it was very subtle.
Following lives of multiple characters.
Greatly written.

Both are about ordinary people trying to live their life in the work place. You might even call them dramas about (among other things) office politics; it's just that Life took place in a hospital and Incomplete Life in a trading company.

Both are medical dramas that provide a more realistic approach to the medical field and the lives of doctors. While "Hospital Playlist" is more on the comedic side in comparison to "Life," both stories show how rewarding yet challenging the medical field is.

Both are based on medical practice and has a gory feel.... The cross is mainly focused on revenge whilst Life is mainly focused on the business side of hospital. There is little to no romance in both show.

The main character in both series are doctors and their work is a major focus. A lot of the issues that the main characters have to deal with in their interpersonal relationships are similar.

About the people who do business and people who actually love their jobs.
Cho Seung woo character is similar to that of Bae in Hotelier.

Both dramas realistically depict the dark side of hospital politics. They both take a satirical look at malpractice and power plays within a university hospital.

Life focuses more on business and what goes on in the overall hospital, while White Tower focuses primarily on the main character's life.

White Tower is a man's tragic story towards his desire for success, his ideals, and his path from nothing to honor to shame to redemption. Life is more of a murder mystery where doctors clash with a businessman who attempts to make the hospital a profitable business.

White Tower was a critical and ratings megahit in Korea, and the Japanese novel it was based off of was a critical and massive hit in Japan.

Life seems to be headed towards that critical acclaim as well.

Both dramas have similar feels in the hospital setting and both don't have romance. But Life is more about political matters and don't have so much surgeries as Heart Surgeons.

This isn't a medical drama, but it felt somewhat similar. They both have abuse in the workplace, corruption and growth of characters (especially the male lead in both drama). As well a caring and nice female lead who stands out.

Both series have a main male lead who is morally upstanding in an increasingly corrupted work environment. Both of their bosses also dislike them and would like to see them fired.

Both focus on daily routine of doctors and the politics affair in it: Money versus medicine, the hardships of being a doctor, the family patients affairs etc

Calm and passive male lead and great female doctor in both!
