Is there any drama (Korean or jap if poss) where theres romance and the female character is cold/violent? or maybe a delinquent?

Thanks
History of A Salaryman- The lead female is a delinquent, with a foul mouth and temper.
Yoona's Street- The lead is cold and a pickpocket.
The Pursuit of Happiness- The lead is cold, just an all around bad personality, especially when it comes to the guy.
Cinderella's Sister seems to fit your description 
cinderella's sister indeed
also Dear Friends, it hasn't that much romance though.
and not to forget Innocent Man has two pretty damn cold female leads
