I feel like aside from the obvious red ones (SA, pdf, grooming etc) and also triangles ofc, a mundane one I dislike is substitution sex. When A wants B but plays around with C. Still ends up with B tho, cuz they the mains. Idc if the characters a player as long as he don't like no one and is just a hoe all around but for some reason when he have affection for someone and still play around, I find that such a put off. People like to argue sex is not romance but imo idgaf. Ew.

I won’t lie, I’m not a big fan of hook up culture especially sleeping around. I see many in BL w/ NO CONDOMS. Helll no! Especially when they have an asshole personality with disregards to people.
I agree, 2nd choice feeling is not it. I still read the substitute trope in Danmei (Chinese novels) for the sake of satisfying grovel arcs.
LEAST favourite BL scenario/trope?
For me, Love triangles.
