Anime/manga version of 'Roxanne'

For those of you who don't know, Roxanne is an old comedy movie strongly based on Cyrano de Bergerac. In both cases, a good, brave, poetically eloquent man is in love with a young woman but feels his love is hopeless, in large part because, however much she cares for him, she is interested in a different man. Knowing this, he does not reveal his feelings but attempts to get the two together. The man is interested in her too, but is rather clumsy and can't get it right, so the hero's matchmaking work makes it to the point where he's actually romancing her through this other guy. Ultimately she truly falls in love with the man, for his eloquence, charm, etc. (basically all the things the hero did in his name or told him to say). The main difference is the end.
So, my question is are there an manga or anime where a man plays matchmaker between the girl he loves and some other guy, and where she falls in love but ultimately finds that everything that she fell in love with was from the matchmaker himself, or finds after the fact about the matchmaker's feelings and the revelation makes her realize feelings she'd never noticed?
In summary:
A loves B. B has a crush on C. A decides to help get B and C together. If someday B finds out about A after she starts dating C, she ultimately decides that C isn't the one she wants after all. If she doesn't ever find out, it's still clear that her love is based upon what A had done.
