Arang and the Magistrate (2012)

Both dramas deal with people who can see ghosts and who are initially bothered by their gifts. Both stories deals with a human who falls in love with a ghost with a turbulent past.

Although it doesn't have the time travel element, it is a fantasy drama that deals with the star-crossed lovers theme. Instead of time, it is death that separates them. Also the chemistry between the two leads is fantastic.

Aside from both being fantasy/romance/mystery, both gave me similar vibes, but they do have some differences.

Similarities:
- Both are Fantasy/romance/mystery dramas, with more mystery in the beginning and more romance towards the end
- Both have creepy fantasy elements and involve heavy emotions/decisions which gives them a similar vibe at times
- Both involve a non-human character
- Both dramas involve a main character looking for their parents/parent
- Both involve exploration of afterlife, gods, and have similar depictions of the journey to death (on a boat in a river)
- Both dramas involve quite a bit of saving

Differences:
- While TOTNT has some historical backstory, it is set in modern time and Arang is set in Joseon time
- Arang involves more slow burn romance where TOTNT the main characters fall in love much more quickly
- While Arang also has fun side characters, it feels much more contained/focused on the main characters while TOTNT has more of an ensemble cast feel

I would recommend these dramas if you think the similarities are why you liked one or the other drama, but if the things that are different between the dramas made you like one or the other drama, I would be hesitant to recommend it.

Similar fantasy world.. like the fantasy world has advanced from then on! The rules also seem somewhat similar.

It deals with the supernatural and fantasy aspect in the Chosen Dynasty along with a romantic storyline.

Unlike here the main is not a witch but she is a ghost.

The Storyline is different but both are equally exciting.

both are romantic comedies with fantasy elements and both have a character who can see ghosts ~ the female lead in who are you / the male lead in Arang and the Magistrate~ also both of them involves a main murder case in which the leads need to solve.

These two are both fantasy historical korean dramas. Both have sweet love story between leads. Lead actors are very talented and have amazing chemistry. 

Both have lead seeing ghost elements, Eun Oh has the ability to see ghosts, so he's used to being bothered by many kinds of ghosts. As a result, he isn’t afraid of ghosts anymore.

Then Eun Oh meets a virgin ghost named Arang.

Both shows are costume dramas, and each have all the elements of a great story. There's tension that keeps you on the edge of your seat, laugh out loud moments of comedy, tragic elements, and a rock-solid romance. They also have chilling/compelling villains that are way too smart to be underestimated.

Tight storytelling, beautiful romance, compelling characters. Your emotions are about to go on a roller-coaster ride.

Both have a human ML who can see/lives with the ghost FL.
