Looking for a Fantasy/supernatural k drama

please suggest me a good supernatural/fantasy show that has more genre mixed in it

i would appreciate if there's some kind of big mystery or a big case with lots of thrill and twists . also i want little bit of comedy , wholesomeness and emotional stuff in it.

ROMANCE IS NOT NECESSARY BUT IF ITS THERE THEN I WOULDN'T MIND IT..

i especially love the

sleek , clean and cozy vibe from a show and want to see it more...

I have watched a lot of detective thrillers so I would appreciate a one big mystery

i absolutely hate the new case per episode format but I wouldn't mind it if all the cases are interconnected.

These are the dramas I have seen related to this request

THE GUEST : I liked it dark and gritty tone , the actors were my fav more than the story here and the one big story was perfect... though I hated the case of the week format I find this drama average

THE REVENANT : as said i liked it clean and sleek visuals , everything felt colder yet beautiful, i enjoyed the mystery and interconnectedness of everything... here too the actors were my fav. thing but less than story

BLACK : i enjoyed it's comedy a lot the mystery was also good but it dragged too long

MISSING THE OTHER SIDE: again cozy , lovely drama with great mystery

KING THE ETERNAL MONARCH: i really appreciated it's comedy and the seriousness and i want more of it
