Both are medical drama, same kind of vibe where the main leads have family situations related to hospitals. In both dramas, one of the main leads have to leave a position in a big hospital in Seoul and move to a small one, with less technology and resources: in Teacher Kim, a countyside hospital and in this drama is a hospital ship.
They're both medical dramas that focus on a young doctor who strives to reach the top and eventually falls in love with a fellow female doctor. Also, both of the main leads have gone through some things in their past that made them enter the medical world and they both have some kind of mentor with whom they don't get along at first. They're very similar if you want to ckeck either one of them.
Both dramas have characters with great chemistry and detailed personalities. But more importantly, they both teach us valuable lessons that can actually be applied in real life. Both dramas are also centered around the workplace. In Misaeng, it is a trade company, while in Romantic Doctor Kim it is in the hospital.
Both dramas have similar tones and motifs. Romantic Doctor Kim deals with medical morals and obligations while Pinocchio deals with how media/news channels impact people's lives (lack of morals and ethics). Both have excellent actors and both dramas will have you crying for the character's struggles.
I know that at first glance both of these dramas seem very different begining from me main place where both stories develop, one is in the judges court and the other is in a hospital, but they both gave me the same type of feel. In both series there is an older main character that supports the two main characters in their growth. Also the older characters go against many people for what is right and end up changing the male lead´s point of view in many things. There is also romance involved but its not the main point in the series. In overall I loved both dramas and would recomer either if you want a show you can enjoy
