Hello! I am looking for a drama with amazing world-building and story, something that makes you feel like you are in a different world. Something that makes you feel like you are not just watching a drama but in that world with those characters. 

It does not have to be a fantasy/supernatural, can even be contemporary history or modern times but something with that immersive experience (that includes good acting, characters, etc). 

The best example I can think of is External Love/Ten Miles of Peach Blossom and I know there are a lot of new Xianxia but the characters and storytelling and visuals all seem so repetitive. That being said, if there is one that is worth seeing anyway, do recommend! 

Thank you!

Seirei no Moribito, perhaps? It's in three parts, totaling only 22 episodes

You might like Luoyang and The Longest Day in Chang’An. Both have the same kind of cinematography, storyline (suspense, action) and characters. Not much on romance tho.

Flower of Evil; Liar Game (both thrillers)  are very immersive because of the acting and the writing, also the cinematography (for FoE). 

Goblin is also good.

Thank you to everyone above! I had actually started re-reading the 90s shojo comic Basara as a way to get my fix. Just started watching Seirei no Moribito and I like it a lot so far!
