both are supernatural historical dramas..with a blending of past and present


both have 2 love stories
1-warrior and person from the present.
the love of warrior is pure platonic one with lot of understanding..and he is always try to protect his girl
and the couple always try to overcome their difficulties together
2--king and queen
the love b/w king and queen had lot of misunderstandings though they love each other a lot...

both have bromance b/w king and warrior and the warrior was very loyal to the king

both have good friendship b/w two leading female characters and help each other to develop their love and all..

both have people who are jealous of the warrior and plotting against him and try to brainwash the king

But the theme of the story is completely different

cuz in faith its just one girl who time travels to the Goryeo era..
and in goblin many people from that era come to the 21st-century in different ways..
