The School Nurse Files

The main characters are both nerdy, eccentric women with a similar feel. They both see supernatural or paranormal phenomena others cannot. Both dramas have similar themes.

Both are Korean Netflix originals with quirky characters and quirky storytelling with unexpected twists. Both have these "weird " vibes.

Mesmo não assistindo Glitch, desde que soube da existência desse novo drama, assimilei The School Nurse Files a ele, principalmente pelo fato dos dois serem de fantasia e terem a vibe de criaturas mágicas

Firstly, MSH is totally different in genre, theme and plot.
But both dramas revolve around school, its students and staff. Both deal with issues in school and how the leads solve them.

In both dramas a lady sees scary spirits/ghosts and feels exhausted and miserable because of it. People around her think she is cursed/crazy (both of them have a weird smile XD). Then she finds a man with special energy that can help her with a touch (such as holding hands, since it passes the energy).

Both feature a female lead who is very dramatic and over the top and a little bit silly.
Both feature a male lead who is just your average good-hearted dude who happens to have a special magical power that can help the female lead do her job.
Both feature the idea of the mystical world just beyond what most people can see and are about helping people.
Both have serious moments among lighthearted levity.

Both are short dramas with a bit unclear, eccentric and somehow supernatural concept.
I think they’re shot/directed in a quite similar manner or with a similar idea.
The plot of both dramas isn’t akin to one another (besides the school setting and the supernatural elements), but they both give you that eerie, uncanny feeling while watching, like something not okay is happening but you’re not sure what (kinda suffocating but interesting story - that’s how I felt).
Both are not really slow paced, but since a lot of events kind of lack bigger momentum and are shown more from the outsider perspective or narrated via inner monologue, it kind of seems like they are.
It’s been quite a while since I’ve seen “The School Nurse Files” but I’ve immediately thought about it after seeing the first episode of “S-Line”.
They give off the same “off-beat” vibe.

Also an absurd situation. The school nurse is the only one who can see the 'jellies" creatures that are invading her school and causing mayhem.

unconventional weird women, eccentricity as a style, grief, loneliness, friendship, societal/institutional critique, trauma, distinctive directorial styles, hidden thoughts and desires expressed, convoluted, incoherent mysteries, knotty, messy, bold and interesting

Both have super power themes in high school, but Mob Psycho has the leads as students. Both of these have odd, offbeat visual styles and involve characters that can see hidden things, plus weird humor.

Both are offbeat, unusual fantasy dramas in which one of the leads hunts supernatural beings/objects and the other has a special power regarding them, causing the two to work together.

Monster? Superhero?
+ weirdness & comedy.
One of the best cg adaptation i love from korea productions. It was so japan vibe. She was a great actress.

they‘re both off-beat fantasy/magical short school dramas based on popular webtoons.

Although they’re very different in terms of plot, they remind me of each other in the way the story is told and the school setting.

It's similar in the fact that both are set in a school and both are supernatural mysteries. I watched Akumu-Chan 7 years ago so I can't specifically point out any other similarities or anything else but I do know that when I watched The School Nurse Files, Akumu-Chan was the first thing that came into my mind.

Other than taking place primarily in schools, the plots are not similar at all, but both of these shows are very unique. Both have a weird vibe to them I cannot describe.
