I guess we're counting Gravitation, too.

I dunno if Loveless counts. b:


I've read a lot of different yaoi manga, but I never keep track of titles, and that was a long time ago, anyway.
I don't read yaoi the way I used to.

Right now? Crimson Spell. But I'm still a bit of a newbie.

Maiden Rose.

I'm pretty sure anyone that has read it has been blown away.

This is going to sound stupid, but I haven't read any yaoi manga except for Junjou Romantica (which I did not like). I prefer web comics such as 'Them Dudes' and 'Honeydew Syndrome' over the actual books you can buy in the store, as well as original content... like, in role plays. :'3 Still looking for a plot line that looks interesting. x_x

Edit: Oh wait; I've read Fake, but that's more of BL than yaoi, right? That one was kinda cute.

Ai no Kusabi (The spaces between) wins hands down. For anyone that hasn't watched it, I recommend you do. There's going to be a 13-episode remake of it, but seriously WATCH THE OLD ONE. It is the staple for what became yaoi as it is today. Sexy, delicious, and the ultimate forbidden love scenario. The novels of it are delicious too. It's 2 hours long - not very long as anime goes, but TRUST ME, it's worth it. Warning for anyone who watches it: There is a sad/touching ending. Be prepared to bawl your eyes out when you watch it.

For me, it's a three way tie between Junjou Romantica (it gets your inner-fangirl to squeal) Gravitation (makes you go AWWWWW) and Only the Ring Finger Knows (which makes your heart go doki-doki! heart )
