same supernatural theme with a traditional background for 90% of the story
goofy main lead with amazing family powers
featuring the annoying ass female lead

Both tells supernatural stories,people who are destined to meet, reincarnation,involves korean fairytale creatures

Miki Ogawa yearned to live the life of a lovely girl and moved to the city from the countryside because of this. She holds a job at a fashion mail order company. Miki Ogawa also has a secret. She is transgender. Although she has a pretty woman's appearance, her sex is male. One day, Tadaomi Goto appears in front of Miki Ogawa. They graduated from the same high school. Tadaomi Goto is flustered by Miki's different appearance, but they happen to become roommates.

I don't know how to explain it right, but both of these fantasy dramas gave me a certain vibe that makes me believe that if you liked one of them, you would like the other as well.
Now, if you haven't seen any of these dramas and you don't know where to begin I could just simply say (without spoilers) that "the gu family book" has more "clear" romantic moments.

Gu Family Book is very touching like Healer although it is a historical drama. Perfect line up to Healer. Great OST especially the beginning story and first OST - My Eden will cure your Healer hangover!!!

Because I feel like You Who Came from the Stars is the sequel to Gu Family Book I will never get to see...

IT ENDS THE SAME EXACT WAY FOR SOME CRAZY REASON. Except Gu Family Book doesn't have a sequel, neither does Rooftop Prince, BUT GFB NEEDS A SEQUEL. It kills me even now..

if you like korean history dramas, and people with special powers, lee min ho, captivating story line, and just plain old good shows. its very similar to this show, except the story line is different. so basically if you like gu family book, you will like faith

These two are rather similar in regards to the main lead having sort of beast like characteristics due to their parents. Arthdal Chronicles is also a sort of historical take on the concept as well, similar to Gu Family Book. The main male leads are either Song Joong Ki or Lee Seung Gi, so you can't really go wrong there. Arthdal is on Netflix though if anyone is interested.

The backstory of GFB is quite similar to Maids, in that a spoiled nobleman loses status, suffers, and is forced to become a servant, causing her to become involved with a quiet, mysterious man.

It might seem a weird recommandation at first, but both dramas are starring Lee Seung Gi so it's a good point. And in both story, he meets a woman who does martial arts and acts like a guy so I think they might be considered pretty much alike!

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)

Os dois dramas envolvem lutas de espadas, conspirações e tensões entre povos.
Yeo Wool e Zhao Jian, as protagonistas femininas são muito parecidas em personalidade: fortes e independentes. Os protagonistas masculinos também lembram um ao outro, no começo parecem bobos e não querem compromisso com nada, quando na verdade escondem inteligencia e força dentro de si. Amo Lee Seung Gi e recentemente gamei no Steven Zhang. Vale a pena assistir os dois programas! <3

Similarities: Prince of Wolf deals with a human raised by wolves who has enhanced strength and senses, and is misjudged by other people (at least initially).
Gu Family Book deals with a half human/half gumiho (fox demon) who has special powers and is treated like a monster by everyone who finds out about his true identity.
Both kinda deal with other people freaking out about their wolf/fox demon rage issues, and have a female lead who understands their true nature.
Differences: Gu Family Book is a Korean Drama, and is set in a historical setting. MC is not as "innocent"? (father of the MC is though).

Male leads similarities:
- Their family dies and they were adopted
- Both have secret superpowers that they are unaware of
- Both have cute, cheerful and 'takes all the blame' personalities
- Both will do anything to save their loved ones even if they have to die
- Gets stronger and clever as the story progresses
- They want to know what happened in their past
- Want to take revenge on the person who destroyed their family

Female leads similarities:
- Both female leads have met their fated love when they were younger
- Two girls fight over the male lead

The drama similarities:
- Both are in historical settings
- Similar situations
- Both dramas are supernatural/fantasy

The drama differences:
- One is Korean
- The other one is Chinese

These two are definitely very similar you should try them out!
