There are actually couple common factors why Bmblb become a thing (and why it's one of the more popular ones)

-They are teammates -They are partners in the said team -They are friends (because friendship = romantic love... The only thing stronger than that is the rival/friendenemy based hate) -They are opposites (Blonde/Black, Quiet/Loud, Introvert/Extrovert, Sun/Shadows, Happy/Angsty, Partygirl/Bookgirl....)

I'm pretty sure everyone can think several "fandom's main ships" that fits to these descriptions. Just add the fact that the voice actors are activelly teasing and showing their support towards it (which in my honest opinion should have been stopped from the start. If nothing else, they pretty much spoiled the whole plot point years ago) and no wonder Bmblb has become so popular.
