Itazura na kiss - Exactly what your looking for. Goofy girl goes for "perfect guy" buts gets rejected the whole time
Suzaku is similar just the opposite, the boy likes the girl and she acts as if she hates him.
Other good romance/drama/comedies I've watched and would recommend are:
Kannon 2006 (my favorite)
Rumbling Hearts (very sad near the end but it ended the way I wanted it to)
Air (Still don't understand that one lol, quite confusing how it ends)
Plenty more just I'm at work and don't have my list handy.
