Romance Manga, shoujo?

I need help. This is going to be very vague, but I read this manga a long time ago, and can't remember the name of it. All I remember is that it's romance. The guy picks on the girl, and then something happens, she gets mad and cuts his hair. I believe he's a delinquent. The style was very similar to Miyasaka Kaho (maybe it is her). Any titles that sound like this?
