Sell Your Haunted House (2021)

- Deal with similar themes such as demons, possessions, and exorcisms.
- Mysterious and dark (the guest is much darker and serious)
- The Guest is more of a pure horror drama and has a bleaker tone in general.

I think that "The Guest" is the best horror kdrama.

Similar vibe, both are comedy-horror stories about ghosts. The main characters in both dramas team up after a rocky start.

Both feature ghosts, mystery/horror elements, and a strong friendship that can be read as romantic but doesn't have to be between the leads.

Both are about a FL who can see, lives with, and is haunted by ghosts. Both FLs are colder/distant personalities, while the MLs are warmer personalities.

Korean dramas about a lead who can see ghost(s). The plots deal with closure and moving through grief.
