Dramas similar to "Revenge"

can someone suggest me any k-drama or asian drama similar to the american tv series Revenge or any with revenge theme? the closest one i've seen are City Hunter and Green Rose ,  revenge themed dramas i've seen already are : City Hunter , Green Rose , The Devil , Autumn's Concerto , Cain and Abel , Bridal Mask , Innocent Man.

Thanks for the suggestions , btw i've been trying to download Cruel City aka Heartless City for a while but either the download it's too slow and would take ages or i can't find proper subtitles , the ones i found are not timed with the episodes and that is really annoying.

I've been downloading Cruel City from doramax264 and the subtitles from there work :)
