I've been using avistaz for years and it's amazing.
https://avistaz.to/Not only do they have every Kdrama, Cdrama, or Jdrama worth watching, but they have popular dramas from every country in Asia. Plus you're in luck, normally it's invite only but it's open registration until the 30th.
As a huge plus, all popular/recent TV shows get marked with a golden star next to them for months or even years, which means it's a free download so it doesn't go against your download ratio. This makes it really easy to keep a positive ratio. My ratio is over 10 to 1 and I watch all the newest shows.
If you want I can even give you some recommendations if you tell me what you're into. Trust me I used to live in the Philippines and we watch more Kdramas than Filipino shows lmao.
