Omg, yes. Great point. I never thought of this before but now that you point it out it does make a lot of sense.
I can feel that too, it's hard to come across a BL comic where the two MCS or even the side couples like each other, usually it's one-sided or for their own benefits or because they're forced to or just wanna play around.
Half of Bl mangas are just focused on sex. It is sad but is not like we can blame the author since yaoi is an echii genre so romance isnt required, they just use some cliche plot as the basis for the sex scenes. If you want love storys you should ready shounen-ai or search for the tag (=・ω・=)
is it just me or does it feel like half the time in yaois they never really like each other? don't get me wrong, i love a good ol enemies/rivals to lovers, or characters that really dislike each other falling in loooove or whatever, but when they're in a relationship i wish it'd feel like they actually... like each other?
