School 2013. Jang Na-ra is portraying a kind-hearted and caring teacher there.

I don’t have a really good match here, but the drama that came to my mind was Crash Course in Romance. Hear me out, though, because it isn’t an ideal recommendation and I know it…however, I thought that its teacher-forward story line here was one of its most endearing.

CCiR contains significant scenes of teachers talking to teachers about teaching. The relationship between Choi Chi-yeol and his former teaching colleague, Jeon Jong-ryeol, in particular, was amazing—and spent some quality time delving into why teachers in secondary education in Korea, teach.

There’s a lot of emphasis on student life in CCiR, but because this drama is essentially about what it means to be a “star teacher” as opposed to an “everyday teacher,” it really can be understood as a teacher-focused drama (from time to time :)).

Black Dog: Being a teacher The drama is not fast paced, but it has a great cast comprised of Seo Hyun Jin and Ra Mi Ran covering the obstacles faced by teachers. I enjoyed it.

From 2014, my my first year of kdrama watching, the first thought that came to mind was 'Biscuit Teacher Star Candy' aka Hello Teacher
I was so desperate to see Gong Yoo again (Coffee Prince was my gateway drama) that I had to buy the DVD set since I couldn't find it online. Very enjoyable show!!

Black Dog was really interesting. There was Ha-Joon as a teacher for the Otter team :p

Master of Study was about the students and the teachers. Bae Doo-Na was a cute English teacher.

In My Strange Hero, the FL is a teacher and the ML is her old student. It was pretty fun.

School 2013 and Black Dog have already been recommended, so these teacher-focused dramas may be a stretch, but
Class of Lies
The School Nurse Files
Moving

Black Dog: Being a Teacher (2019) takes a deep dive into contract teachers at private schools, and Seo Hyun-jin is excellent in it.

Nobody Knows : A detective and teacher story where the detective is female and the teacher is male. A little character subversion trope.
Crazy Love. This one is very good.
Sky Castle.
High Class. I'm not exactly sure about this one. I don't know if the main focus was on the moms or on the teachers.
Crash Course In Romance.
Moving : This isn't at the fore of the story, when it was time to spotlight on it's teacher, it was just done well.

Black Dog is the only drama focusing in teachers' life I've seen. Don't remember much except for Ra Miran. I thought Chun Won Hee was one of the teachers, turned out it was Seo Hyun Jin. Didn't even realize Ha Jun was there, too.

I might add Kim Ha Neul as homeroom teacher to a bunch of rebellious boys in Gentleman Dignity was pretty memorable, too.

Moment of Eighteen has a strong focus on the different teachers attitudes in terms of being supports for the students or being susceptible to the bribes by the parents.

My first love time travel teacher ends up teaching his teen self.

The Queens classroom is about a teacher who uses unusual techniques to teach the children about the harsh reality of adult life. It was too harsh for me. I initially thought it was like Nanny McPhee but the emotional impact of her manipulation was too much for me as we see the children falling apart emotionally as they learn to make their own choices and have confidence in each other. I wanted to see how it ended but in the end decided it was not worth the stress. The lead child actress grew up to be the female lead in Moment at Eighteen and Salon De Nabi.

MASTER OF STUDY

NOBODY KNOWS

WHAT'S UP

SPECIAL LABOUR INSPECTOR JO

Master of Study
Class of Lies (Mr. Temporary)

In Twinkling Watermelon, it isn't a formal teacher, but the ML does a lot of sign language teaching to his future mom as he travels back in time. I love shows with sign language and try to learn a few signs if possible. Just watching the family he is in is very interesting also as he is the only hearing one in his family so there is a lot of signing which the actors do very well.

A Good Day To Be A Dog.

Earlier this year, One Day Off starring Lee Na Young as a high school literature teacher had a couple of excellent episodes that didn't focus on the classroom, per se, but was the most thoughtful kdrama I've seen in discussing the developmental relationship between teachers and students.

I enjoyed I am Sam. It's mostly about the students but maybe a 60/40 split. I'm particularly fond of the scene where the teacher played by Yang Dong-geun has his students rapping in class.

Angry Mom. The FL wasn't a real teacher, instead she became one to get into the school to defend and protect her daughter. Very good drama.

Gangnam Beauty

True Beauty

Dream High

Doctors (Kim Rae won was PSH’s teacher at the start)
Biscuit teacher star candy 🙈
And what was that one with ahn jae hyun and the woman from hwayugi? She was a PE teacher and he was chairman of the school board

This may be a little off tangent (and I cannot recall being part of any k-drama teacher subject matter), but YonHap News reported today the number of elementary, middle and high school teachers who took their own life over the past decade amounted to 144.

Teachers across the nation have recently demanded better treatment and guarantees of their authority in classrooms in the wake of a series of suicides by teachers who apparently suffered from unruly students and malicious complaints from parents.

I have watched some dramas where some of the main characters are teachers, but teaching is not the main plot:

_ Solomon's Perjury.
_ Something about 1% (2016).
_ At a distance, spring is green (here some teachers have their own arc).
_ My Lovely boxer.
_ Seasons of Blossom.
_ Monstar.

Melancholia starring Lim Soo-Jung & Lee Do-hyun

The Real Has Come

**ducks behind sofa to hide**

ML in REVENANT is a folklore professor in uni, which is VERY important plot-wise, but it's likely not the drama you're looking for lol.
Something tells me this theme must be all rage in cdramas as well... Probably more in costume shows than modern ones tho, for extra glamorous flavor.

When We Were Young 2018 (CDRAMA), and Sassy Go Go are more student focused but they also have very good teachers as core parts of the story too, so might work.
They're also my top two HS dramas that I'd recommend anyway.

My Strange Hero and Special Labour Inspector Jo both have unconventional premises, especially regarding what you're looking for haha, but they're both fun and have good characters.

The CDRAMA RAY OF LIGHT has quite a strong focus on in the teacher being the centre, the ML almost, and helping all the different kids. I didn't like the ending and I thought some of the development was rushed/too easy, although some of that was due to the nature of the drama.
I have stupidly high standards though and others really enjoyed it haha.

High Kick which is a sitcom/not a drama has two main characters that are teachers. This is a hit or miss kind of show with some very funny episodes mixed into some not so funny parts. I think it was very popular when it aired and launched many careers. The parts with the teachers are really funny. This is older, 2007. I really liked watching a k-sitcom with it's 1/2 hour episodes as a change from the k-drama. It is pretty over the top at times. The more I think about it, there are lots of dramas with teachers, many of them in music settings like Dream High, Do You Like Brahms, Penthouse.

Law School focuses a lot on the professors as well as the students. To me, the main professor is into the best kind of teaching as he wants his students to learn not through memorization but by overcoming difficult moments where they have to find the answer, band people together, and strategize. His true star student looks like a bad student, as she’s awful at memorizing, but she is the best at all the other skills. It’s true a lot of the drama happens among the students, but I enjoyed it most due to this meta teacher perspective.

KBS Drama Special: The Red Teacher(2016)
Lee Dong-Hwi as a teacher at a all girls high school.
Jung So-Min as the student who authors a erotic fiction novel .slandering a army general.

i can name a few.

School 2013
Crash Course in Romance
Master of Study
I also consider Dream High.

Crazy Love ans Crash Course in Romance were goos examples of teacher focused dramas.

The School Nurse File and Moving had good teacher-student portrayals but not necessarily teacher-centric stories.

What about "Big"? LOL. Joke.

Real recommendation: Seasons of Blossom. ^^

The Chair (Netflix) isn't a kdrama but it stars Sandra Oh as the chair of a small university English department, and she has Korean father and there's some Korean dialogue in the show as I recall. Anyway it's a short fun but fun series about life in academia.

Ive never watched this but just recommending for the heck of it - Biscuit Teacher and Star Candy, starring Gong Yoo and Gong Hyo Jin. I’m sure the name makes sense in Korean. I also found out the boring alt title is Hello My Teacher.

School 2013 for something that's more student centric and I love to see Black Dog as its equivalent but for something that's more teacher-centric. Also more people should watch Black Dog that thing is one of the most heartwarming drama I've ever watch tbh

Surprised Biscuit teacher Star Candy isn’t mentioned. Gong hyo-jin starts off this one as a HS teacher and then Gong Yoo ends up being one by the end. 😂
