These are the ones that I always come back to

Less of active BL showing because of chinese censorship but their connection is undeniable. 

This story, world and everything else that comes with it, has been my hyperfixation for YEARS. I can only HIGHLY recomment the books - which this series is based on : The Grandmaster of Demonic Cultivation.

This is my hear me out BL. I know it is toxic. I know a lot it wrong with the dynamic between the couple but I still hold it dear. It is one of the frist Thai BLs that I ever watched and Mew and Gulf where the first Thai Actors I started following on social media.
