Hmm, I'd say the first of the Mujihi series (wonderful series which I recommend to every fujoshi), which is called Mujihi na Otoko. Uke has loved seme for about a year until he finally confesses (also kind of forces himself on him) but the seme realices that he loves him. It's a really beautiful series! :) And then the rest of the series (Mujihi na Anata and Mujihi na Karada) is just them together and hardships that they face.

It's one of my favorites manga!
Uke has an unrequited love for seme, i would prefer a long developed one till the seme realizes that he loves the uke back.
