K-Drama that are similar to Shows like Supernatural and Buffy

I love the structure of 'Main Story + Aventure/Monster of the Week' of shows like Supernatural, Buffy, Smallville etc.

But is really hard to find korean shows like this for me.

So any recommendation? Thanks in advance.

Thank you very much emeraldarrows. I'll add the four shows in my watchlist.

Revenant has one big baddie, but it also features different ghosts in each episode--at least early on.

And I don't know how open you are to older dramas, but Secret Investigation Record is a good one. It's arguably closer to The X-Files than Bufffy or Supernatural, though. If you don't mind the lower production value--especially compared to new dramas--I really recommend it.

For K-Dramas similar to *Supernatural* or *Buffy*, try *Goblin* (2016), which blends romance and supernatural elements with episodic adventures. *The Master's Sun* (2013) and *Let's Fight Ghost* (2016) also feature ghost-solving mysteries and supernatural themes, offering a similar structure of main story plus weekly adventures.
