Scheming FL

I dunno how many dramas I've seen with scheming/strategic MLs or FL antagonists, but rarely any true scheming FLs. 

Got any recs? 

Currently watching Plot Love on iqiyi and lovin every minute. 

There are actually quite a few of them, some I can think of right away are these; 

So for korean dramas;
The World of the Married
Secret Boutique
The Good Wife
Big Issue (although there is also a scheming male lead here)
Whisper

For chinese dramas;
Rookie Agent Rouge
Stealth Walker (I really recommend this one)
