Which couple do you like? Or which one DON'T you like?
When I say 'Mainstream Yaoi/BL couples' I meant the couples that the fangirls decided to make. Or in some cases, the couples that the mangaka decided to make (or at least give hints about them). But the storyline of the anime isn't really BL. I guess Kuroshitsuji is sort of BL, but who cares, man. It's Sebastian...
(You have no idea how difficult it was to find DECENT imaged that are PG-13. This is PG-13, right? Of course it is.)
Or if you don't like any of the pairings (.●´﹏`●.) then just say which ones you like.... as long as you say it... say ... it.
