I remember thinking, when I dropped this series halfway through in my early days of anime fandom, that I might find the show more interesting if the main leads were pretty bishounen (because the way the show was, I got the feeling that it "wasn't for my demographic"). But...in hindsight, I'm not so sure. I'm not sure if I would get attached to the MCs any more if they were guys (because they still come across as being cold and uninteresting to me when I try to change their genders in my head), and the story still would've been slow, and I still would've been frustrated with the episodes where I felt the plot still wasn't going anywhere...

So. Yeah. I dunno. That would maybe help with the yaoi fandom but I don't know if it would've made that huge of a difference.
