Asian dramas with a morally ambiguous female lead

I'm obsessed the The dramas that have a female lead who isn't just the background in the main plot point, but then suddenly becomes important as the ml love interest. 

Like the plot is centered around a goal or something she has to do etc.. and she is willing to do anything(bo matter how bad) to achieve it.

I also want her to be an strong and smart female lead. I hate it when she has to rely on everyone else to get anything done.

Thank you!
