Hi, I was looking for a romance manga where the girl is the delinquent and the guy is good.

I hope the guy isn't a total loser. Just a normal, nice guy.

• No yaoi / yuri, oneshots or really short mangas please.

My destiny is to be forever free, in ecstasy on a hill that awaits for me.

Yandere Kanojo is the only one I can think of at the moment. It doesn't exactly fit your requirements though.

I think The kidnapping of Minja Jo's Boyfriend fits what you're looking for: http://www.mangaupdates.com/series.html?id=6151

onidere?

Can we say Haruhi Suzumiya is a little delinquent ?
Or it's more eccentricity, I think. 😀

She's ex-delinquent (and goes back to being a delinquent for a short while) in Shinshi Doumei Cross.

If you've ever thought or said "Nice Guys finish last" and really meant it, then you should probably read this LJ post by DivaLion. It's incredibly insightful whether you're male or female.

From a bumper sticker I like:
"If you're gonna ride my ass, at least pull my hair."

Well, I suppose Superior could apply since you didn't specify no fantasy... even if "delinquent" is not really the right word for her.
