One more and I promise I am done:
Sekai-ichii Hatsukoi
It is the most romantic gay love story that I have ever seen about two guys that have loved each other for 10 years, but due to misunderstanding broke up in high school, only to fall in love again. The setting is in a publishing company (hint hint metaphysics alert ). There's something about unrequited love that just makes my heart jump a few steps faster
Oh, I almost forgot 07-ghosts is really funny and interesting too.
Mikage and Teito's relationship is so cute and sad. (When Mikage dies, I couldn't help but cry Seriously watch it )
I've watched the entire series, kyo kara maoh in japanese. Good show and lots of subtle humor. The two guys actually adopt a daughter (If that is not gay subtext, I don't know what is).
It's not really Shonen-ai or Yaoi, but the story is pretty good for a fantasy storyline. I advise watching the original Japanese with English subs as it extends beyond season 2.
Just be careful you don't end up with certain Dōjinshi that will forever change your views of certain character relationships
I am re-watching Descendants of Darkness for instance, but there has been a lot of good ones over the years.
