Go watch Hakkenden. It's like a BL harem basically. And it got pretty intense (gay wise).

oh and K got some super gay scenes here and there as well. Tho it's not the main theme. But I tell you, once it gets its gay moment, it's super gay LOL. And sorry for spamming....

I agree that it's not worth it to pursue Zetsuen no Tempest because I myself stopped watching the anime after a few episodes. No hints on bromance because one of the lead guys was still inlove with his step-sister who was the girlfriend of the other main chara. I HATE that girl, that's why I dropped this anime. But the art is good. Hakkenden is really nice! Mangaka is Abe Miyuki of Super Lovers (and some other great titles like Komatta...) and it captured my interest because of all this BL hints. :D Owari no Seraph might be a good choice but slow built.
well, Iwas recommended by someone to watch zetsuen no tempest, it says the main two chara is having a bromance feels,, but I kinda reluctant to watch it cuz the synopsis tells me that the chara is in love with a girl and they can't move forward from her (sorry if anyone see this as spoilers) well, what to do guys? do I have to watch it cuz what I need now is something reaaly bro one like free or 07 ghost,,,,
sorry for my rambling, hope to see your replies all
