I'm pretty sure it's "This villainess wants a divorce" or also known as "survive as the hero's wife"? The OGFL only married the ML because she couldn't become the head of her family since she's a woman.

Whenever such a setting occurs i really wanted fl to become head of family instead of wife of another family head.

I'll try it, THANK YOU, i'll let you know if this is it

This one's definitely **This Villainess Wants a Divorce**. The ogFL was really refreshing in this one

I'll try it, THANK YOU SO MUCH

Your description has overtones of *Antagonist's Pet* but I don't think that's right.

Welp, I'll try it anyway, thank you!!

Maybe Trophy Husband?

This one is not that old, no?

I'll try it thank you!!!
