great historical dramas, with decent plot, interesting story, multilayered characters, relationships, emotions, visuals and everything... no (or much less) cliches, no vuxia and staff like that:
Arthdal Chronicles - it's more prehisorical alternative universe, but it's best ever not modern Asian drama, there is nothing like to compare, only "game of thrones"
My Country: The New Age GREAT with unforgettable bromance (enemies/friends)
The King in Love Beautiful story, more romance focus (amazing romance and bromance)
The Rise of Phoenixes classic historical drama, best historical Cdrama
Chuno very very good, quite different from usual historical dramas
Warrior Baek Dong Soo also great friends/enemies story and unforgettable anti hero SML (star of the show), if you will like "My county" you can try this one too, though as drama it can't compare to "My country", this one is way primitive, but bromance (like in my country) is so amazing, it's worth.
Chuno also has some similar vibes but is also better as drama.
