Koiyume Lover
This author never fails to make the characters express their love so loudly, I am taken away every time I read each manga. Uke-kun relies on a little zodiac icon to lead his way into seme-kun's open arms, their love is interesting and hot.
Hidoku Shinaide
This manga I enjoyed, mostly because of the romantic parts but it does include a relarionship starting after a rape. I've seen many people dislike it because of the beginning and such, but if you try to at least stick with it until volume 4, you'll start to see the real love.
Yarisugi Party Night
I don't care for promiscuous* boys, but I adored the romance arising from playboy seme and girl-crazed uke. It really made me love this story a lot, not to mention the tasteful scenes the author slipped in there. ;*
Sayonara Alpha
A superior Alpha student council president is actually an Omega! Super sweet story of a fated pair with quite the issue, ten years in between their ages.
Kawaii Obaka-kun
Uke-chan in desperate need of money decides to try out prostitution to make up for a debt, and unknowingly meets a love interest?! Hot, steamy and very detailed adult-time scenes with a drama and love typed added in.
