FirsaFirkan:
What about thai?
I'll include some Filipino and Indonesian too :)
War of Y (2022) - ep 7. 49 min in (I think it's on YT, you can tell its explicit bc i actually wrote the time?) Thai, BL, rated MA
The Legendary outlaws - ep 1, 2, 4, & 6 (on YT account Mono29) Thai. I absolutely loved it, but there are no actual eng subs. Still pretty great if you love action/thriller
City of Stars (2020) - ep 1 (the first 3 eps are on YT) Thai, BL, rated MA, he's in like every ep, but he's not one of the 2 ML.
Rerun - ep 1,2,3, & 4 (YT account one31) Thai, not great subs if I remember correctly, not sure he's exactly a ML tho
Cinta Selegit Dodol (movie, also on YT) - Indonesia, I feel like the asthma is pretty well portrayed, but I could only find auto translate for Eng subs
deni murid bang jampang (movie, again YT) - Indonesian, Karate kid knock off. Pulled the whole "willpower cures asthma", also only auto translate for subs I think
Oh, Mando (2020) - ep 1 3/3, 3 1/3 (on YT) Filipino, BL, rated MA
Boys' Lockdown (2020) - ep 4 & 5 (web series on YT) Filipino, BL, can't remember if it was explicit or not.
Bonus: Dead Friend Forever (2024?) - basically just 2 small mentions of asthma, and the whole thing is either explicit sexually or in other ways. but it's a pretty good horror/supernatural, if you're into that. It's also BL
