recommendations are not just about similarities. if you watched mr sunshine 1st, then her private life could be like healing medicine?, and if it's the other way around then please beware, mr sunshine is not a romcom ;p
but both male leads have that serious yet dorky side? and both female leads are strong and independent women~

both are romcom office dramas. both female leads are independent and smart though granted, no one can beat mr lion :)

if you liked one of these then you'll surly enjoy the other too. they are not really that similar in plot or characters, but as someone who always looks for dramas with great female characters, I love connecting these dramas ;)

Kim Soon Jung had that strong confident in her work kind of vibes, which is kinda similar to Woo Ah Jin.

both have real strong independent women leads. though I'd like to give Nam Jung Gi more credit, he is kinda like Woo Ah Jin's husband? they are both naive and pushovers? it's not a bad thing though, for MTANJG ;p

these 2 dramas also have that "cold blue" dark tones. one is female centered and one is fully male centered, but both are character driven stories

talk about woman power~ both are female driven stories with multi layer female characters. recommendations don't really need to have similar plot, but they are both awesome ;p

there are dramas that have a "cold" tone to it. they are relaxing and somewhat as realistic as dramas can get?

great dramas need to be connected together even if they don't share much in common. both of these dramas are high quality masterpieces. and both have interesting and strong women

Diary of a Prosecutor can be considered like "the daily lives of prosecutors", while Live was the daily lives of cops. both are taking the realistic approach to these commonly seen jobs in dramas.

Black Dog can be considered like "the daily lives of teachers", while Live was the daily lives of cops. both are taking the realistic approach to these commonly seen jobs in dramas.

Both main characters are new at their job and they are struggling with it, also both 2nd lead characters are like mentors
