https://avistaz.to/ it's a private tracker and have to get a invite.

Ok here you go, hope this helps.

Dramaday.me - Very good but they have link shortners.

Onlykdrama.com - My go to if a show is available in there. Direct link without any shortners.

Minidrama.net - You will find some drama that you can't find elsewhere, uses link shortners.

Dramaday.online - Another ddl Site. Mainly for variety shows.

Sinflix - A rentry with a lot of dramas with multiup links.

kdramahood - You will have to download each episode seperately but it isn't ad filled.

It's not quite a DDL and it's limited to what is posted, but this Telegram channel has been great. They've been posting newer series as they come out. https://t.me/kdramacxnat

I'm not sure how muuuch it has but I looked up a few on Kodi hooked up to real-debrid and it looks like there are links!
