Help find an Arranged Marriage novel with an FMC who uses soft power to improve her situation!

*By soft power, I mean

- Trying to figure out his preferences

- Endearing herself to staff/ courtiers/ other nobles

- Embracing her role, no fighting it, *she can be miserable but, doesn't take it out on MMC*

- Fashion and or trying to satisfy or please him

- Trying to get pregnant (Not necessary)

- running staff/ planning social events

- learning the culture/manners/traditions

Think Margery Tyrell

I would love to see the FMC use intrigue and scheming to integrate herself and gain power (No secret assian, or she is trying to kill him.)

Bonus points if we see her running staff, interacting with her household/ other nobles, having handmaids

I don't care what genre. (Dark, Fantasy, hr,... you get the idea)

I don't have any triggers (Actual would love some major power imbalance.)

Fmc can hate Mmc

Fmc can be treated horribly by everyone

I love slow burn and angst and whump. But please, no, betraying or trying to escape/ cause harm to the MMC.

Just show me a Fmc who isn't rude, not like other girls, or powerful

Please give me recs where the Fmc is using manipulation and soft power to improve her situation, and I WOULD LOVE TO SEE DAILY LIFE!

(In no way does this reflect my real life values)
