omg same, i want them too but they are very, very very few. also, i think the reason why is there is no point making guy A a main character so there's almost no story like it.

if you are interested, i had an unrequited love list where i have marked the mangas with love triangles but the MC did not end up with the guy he likes but ended with another.
look for the little flags
Is there any yaoi out there where there is a love triangle and the protagonist ends up with the second guy? [ the "rival" ]
