Looking for dramas with SFL who are very possessive or at least preserve to get the ML. ML should end up with FL though. 

Can be Chinese, Thai, Korean, Turkish etc. 

Bonus if they are historical or fantasy dramas, Like Ashes of Love or Princess Wei Young 

I think, Princess Silver or Legend of Yun Xi have SML that could fit your request.

You might also want to try The Legendary Life of Queen Lau for a more  lighthearted historical drama with a persistent second lead.

*edit: I am sorry, I misread your request. Can't really remember any SFLs, that fit your request.

Leh Ratree: The SFL used to be his wife, but lied to him.  Once he finds a new girl, she gets obsessed. Trying to get him back. She is definitely evil tho. 😂

A Camellia Romance: The SFL is the ML's cousin. She has always been in love with him. She and her awful mother try to do anything and everything to get her the guy. Fair warning, she got on my nerves so easily... the whole time I was yelling at her though the screen to go away.
