Good Asian crime / sci-fiction / thriller series?

I'm looking for recommendations for Asian series (genre given above). The series I particularly liked were Black (Netflix) and Rugal (Netflix). So if it were something like that, that would be great. Especially with Black, I found the backstory from 20 years ago quite exciting. So if someone has recommendations then please write an answer with the associated streaming service.

There would be old boy, it's worth looking through to the end. Then the cop, the gangster and the devil, I saw the devil,. Parasite, Parasyte; 1, and the usual Ring and Grudge movies!
