Black Dog (2019)

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

Similar concept, same thing, both dramas involves Korean culture of academies for student that have them prepare for universities after school. Both series have internal teachers, fighting for positions, new challenges along with other rival academies and preparing lectures, classes, concept for studens.

this is another "recommendation doesn't mean similar", but both have a slow healing process and the main guy in Nobody Knows is also a teacher and some of the plot happens in a school

They both show the internal politics and struggles in a workplace: for Black dog is a school, in Hot Stove league is a baseball team. They both show faults of the systems they sorraund them. Both have no romance, but have a good portion of comedy and sometimes tension.

Han So Mang may not yet be officially a teacher, but she and Go Ha Neul both have hearts that go out to students who may look fine but are silently problematic. They are both set in schools and present students healing from painful experiences.

Both Agency and Black Dog share the vibe of female struggles in a work environment. In BD she was an uncertain newbie that didn't know if she'll survive the high tides while in A the fl is already well established and more than proved herself in her position but still the struggles and instability are the same, also the supporters

Lee Chang Hoon is also in both as the sweetie supportive coworker who's almost like a brother to the fl

Also both fls are one of my queens

this is a totally different story from each other.
but the vibes, atmospheres, and cinematography are very similar to each other, also, the main female lead in DYLB had the same shy personality of the main lead in black dog yet unique and refreshing, although they are shy but they stod for what they think it right.
if you like "do you like Bahamas?" I totally recommended you to watch "black dog" .

both dramas take place with teachers/instructors as the main characters while one is a romance and the other is more of a slice of life i think that they are similar enough character wise that the same audience might enjoy them both

both kinda talk about the work environment from a newbies pov. in both they go through alot of tension and struggles trying to understand the dynamics of a not so perfect and suffocating block that one can't easily fit into

Drinking Solo and Black Dog both centre on the educational system on South Korea.

While in Drinking Solo -which has a lighter feel- de follow teacher in an academy for aspiring civil servants, Black Dog -which has a darker ambiance- is about the daily life of teachers in a high school

Realistic dramas showing the daily life of Korean people ar work. In Black Dog we follow high school teachers and in Argon the employees of a TV chanel.

Both of these are work based dramas which show the struggles of the lead as they work within a temporary placement. In black dog it is a case of the FL being a temporary teacher whilst in kkondae intern, the second ML works temporarily due to being on an internship.

Both dramas contain characters which work within a school environment. Whilst love with flaws is more lightheaded being a romantic comedy, black dog is more serious in detecting the issues faced within schools.

Both these dramas show quite realistically the struggles of some of the MC making her first steps on the professionnal world.

Black Dog similar to My Mister because they both have cold, slow and calming vibes. I also found the female characters kinda similar
