Badass Female Leads

I LOVE badass female leads in dramas. I want to watch a drama where basically the female has a double identity, and in reality, she has the upper hand in everything. Maybe she pretends to be poor, but she is actually really wealthy with power. Just something similar it doesn't need to involve a hidden/double identity, but a powerful and smart female lead. It doesn't matter what genre it is, but the only thing I can't handle is infidelity. It doesn't matter what country is from.  Thank you! 

I just know these, actually these FL not a baddas, but they keep low profile and hide their identity as a rich.
