Black (2017)

In both shows:
> The Female Lead has the ability to see ghosts. In Black she's born with the ability, whereas in TOTNT she developes/is given the ability.
> The Male Leads have few friends.
> The Male Leads are't human. In Black he's a grim reaper and in TOTNT he's a fox.
> The Male Leads are constantly protecting the Female Leads, more so when they develop feelings towards them.
> The Male Leads are strong, cocky but hilarious.

Having said that, Black is a lot darker than TOTNT.

Zhang Jing Yi is the FL in both. The chemistry is natural. The relationship had depth. However, BEITD does not have a satisfactory ending.

Black is about a detective possessed by the Grim Reaper. Ha Ram can see shadows of death. These two struggle to save the lives of people, breaking the rules of heaven.

Both dramas are OCN master pieces with a fair share of dark content. Don't expect too many 'nice' scenes since there are not any...

Both female heroine can see ghosts
Although Black is truly a serious crime-drama-fantasy, The Master's Sun is more light-hearted, romantic drama
Both dramas are worth watching!!

Both dramas contain a supernatural aspect. and the main leads are “possessed” in some way. In Black, the main character’s body is possessed by a grim reaper; in Oh My Ghostess, the main character is possessed by a ghost. Both also have crime/ thriller aspect, but Black is much darker than Oh My Ghostess.

Both female heroines can see ghosts
Although Spellbound is more on the lighthearted rom-com, both drama and movie are worth watching
