Revenant

They both have a tones of fantasy realism and is related to the beings from the other world.

Island has a slight romantic/comedy touch while maintaining the element of mystery and horror (Which in my option is very hard to establish). The cast also has a wonderful chemistry with each other, which makes it a delight to the eyes.

This also has a part two (which is a continuation).

Fantasy drama that fight ghost or demons... both short kdrama that you can binged watch all episode in one sitting...

It has a similar dark vibe to it.

Revenant and Head Over Heels actually feel surprisingly similar once you line them up. In Revenant the female lead is the one pulled into the supernatural, dealing with possession and a dark mystery that completely flips her life upside down. Meanwhile, in Head Over Heels, it’s the male lead who suddenly gets thrown into the spirit world, forced to deal with ghosts and strange abilities he never asked for. Both dramas pair the affected character with someone who helps them navigate the chaos, creating a partnership built on uncovering hidden truths and trying to stay one step ahead of forces they barely understand. Even though Revenant is much darker and Head Over Heels leans more romantic and warm, they share that same core idea of ordinary people being dragged into the supernatural and having their lives changed forever.

Similar vibes. Both suspense thriller.
same more on resolving possessed people and looking towards the root cause.

FLs both have powers that are inherited from their parents, and their show charts their journey to reconciling themselves with that power and coming to terms with the death/disappearance of their parents.

Entertaining big families that come close to heart.
The way both dramas deal with family-only dynamics is peaceful.
Full of comedy.
Heart-filling romances.
Double in-law couples.

Past in the form a ghost or supernatural events happening in the present. The dynamic of a older detective finding out the truth behind with a younger female lead.

This drama is similar because it has something to do with spiritual Rome and afterlife type of events. It’s similar and different at the same time in it’s own way!!
