O Livro da Família Gu (2013)

Both are historical Korean dramas with similar pacing and tone, with the first couple/few episodes focusing on the ML's parents before the ML grows up and becomes the focus of the story. Both MLs have superhuman strength and are feared/wanted to be killed by others. The FLs are the ML's second love, not first. Both featuring supporting characters who are courtesans and are heavily involving in the politics of the country. The villain remains largely in power/on top for the entire drama, only meeting his end in the final episode.

Non-human-human relationship. The leads gets together and separated by fate. Both cuples meet still children.

Both are historical Korean dramas that have beautiful cinemaphotography and tell a tale of star-crossed lovers. Both also deal with underlining supernatural themes.

Both of them are talking about a main role the not a human..but the other is not
And both of them ends with the died of the main role
But gu family book is historical drama ....
But you should like it more than orange marmalade...

Both dramas are a fantasy-romance in a historical universe.
Both leads have supernatural power and try to find a way to get ride of their curses to save their lives and finally be able to live a normal life with their beloved.

If you like historical dramas with a lot of action and a slight comedy, these two are definitely your type.

- both the male lead have supernatural power or something even though the main lead of gu family book is not a prince or soon to be king.
- both have a combination of supernatural and historical genre

They are historical fantasy k-dramas with star-crossed lovers, good acting & pairing and great storylines.

Both of these dramas are fictional stories about half-human man who fall in love with human woman which ultimately makes them have to deal with death as a consequence

The female leads in both the dramas are disguised as a male. Both are set in ancient times.
Suzy's character in Gu Family Book is a girl who never goes anywhere without her sword and prefers to pass for a boy

Love, politic, drama, epic characters, more epic characters - and more drama! With humor. Emotional jurney across Korea.

This drama is about a Half human Half gumiho who wants to become human and its similar to this drama.

They are both historical dramas and have a little bit of comedy in them mixed with action and suspense. Although, The Tale of Nokdu does not have any fantasy in it - it is still very entertaining and humorous. Definitely worth a watch~

So many elements of Gu Family Book remind me on Inu Yasha:

both guys are half human, half mysthical beings; both have a girl they love from their past and a new love; both are going through hard times; and both would do everything for the ones they love and protect them with their own lifes.
These are just examples. I could mention many other similiar things.

As Holy Pearl is kinda a remake of Inu Yasha, you might enjoy this drama, too.

No one related these 2? I felt pain watching them both. .... and the ending is awful in both
