I have not finished these so I don't know how good the endings are...
Special A (also comedy the romance doesn't really come in very much to about mangá 5 I think)

Alice in the country of hearts( the first 9 chapters only really have hinted romance though)

Oresuma Teacher

And Arina Tanemura makes good mangá with romance in it from her I have read
Full moon o sagashite (very good, romance is not the main story but it is still defiantly a big part of the manga)

Gentlemans alliance cruz (good, same descrição as one above)

Sakura hime (I didn't like it much but you might..)
