Hmm...
I can think of at least two with really good reviews:
Addicted Heroin (Chinese webseries, they were gonna make a second season, but it got cancelled because of the ban)
The Lover (Korean drama, features several couples and one of them is about a gay guy and his roommate)
I haven't fully watched them yet, but I snuck a few peeks and they looked great!
Sadly enough, there aren't a lot of BL dramas out there. It's often either movies, webseries or just fanservice.
