Blood (2015)

In both plays the main actor has fantastic medical capabilities and most of the scenes are shot in the hospital makes it even more interesting for the fact that patients arrive with wounds and that doctors must treat them and they are always the challenge of who is the best surgeon of the hospital, the SOUNDTRACKS are too cool. Just watch both of these dramas are very nice

Vampires are topic and vibe is very simmilar. Both are romantic with comic moments.Out of all vampire drama those two are the most simmilar.

Set within a hospital. A vampire works as a doctor. A battle between good and evil as well as immortal love takes place.

Though they might be a bit different, Blood is still a medical drama which I have enjoyed as much as this one. You should totally give this a try, you will never regret it :D

Both are dark fantasy dramas. The MLs have a condition that makes them consider themselves to be monsters and have to suppress their violent tendencies. They start out hating the FLs, who are normal humans, before getting to know them better and deciding to work together. The villains act like they want to be friends with the MLs and see themselves as more than humans. Both dramas have some humorous moments but are overall tragedies.

Orange Marmalade and Blood are both vampire dramas.
In Orange Marmalade (it didn't air yet), if they follow the webtoon, it should be about a female vampire in high school falling in love with a boy who hates vampires.
In Blood, the vampire is a surgeon looking for a way to become human and trying to figure out who killed his parents.

These two dramas have a similar supernatural feel about them.
Blood is modern about a doctor infected with a supernatural virus, and Gu Family Book is about a half-gumiho.
The main characters personalities are different but they look very similar when they are "transformed". (Green eyes long nails etc)

Similar themes of:
Forbidden love
Supernatural creatures
Humans in situations with supernatural beings

Both series are about vampire it also has
Action
Doctor
And the romance is good
But most importantly the main is totally hot

They both are about man with special powers.its not a typical vampire story . looking to the subject from a different aspect makes it unique!

Different stories but you just can`t not watch any of them, in both romance, vampires, and hot guys are there :P

Supernatural creatures in the real, every-day world. Interactions between human and otherworldly creatures

they are both medical romance dramas and the main leads have special talents when it comes to medicine.
