Hello guys I'm looking for dramas where Female lead and second Female lead are competing actually in whole drama....

Both of them must be smart and strong....female lead must fight for good world and second Female lead must fight for her dark and bad world...

And it's ok if the romance isn't important part of drama but it must be one of these thing which female lead and second Female lead are fighting for.

Somethig like:

Dongyi

Jewelry in palace 

Thron brids


TThank you for your help^^

Not really about "good world" vs "dark world" but if you want competitiveness :

The Innocent Man

Pasta


Special mention to "Woman Of Dignity" which in a way is borderline friendship/rivalry, well you need to watch the drama to actually understand what I mean.

Ja myung Go

I Need Romance 3

Dream High

Feast of the Gods

All about eve

Shine or Go Crazy. They're both fighting for the male lead. One fights to help people while the other is a creature of the royal court.

Moon Embracing the Sun if I remember right has it. One girl is set to marry the emperor while another girl loses out. The family of the girl who loses out decides to fight back.
