The FL we need

FL divorces her scum husband and marries another kingdom's ruler.

Princess collecting her jewels for her harem- I mean to help her get on the throne

FL is a fan of ML and helps to increase his popularity with the public so that they're aren't so afraid of him. ML falls first, FL adores him as a fan but deep down I'm sure she likes him

FL gets to switch bodies so that she can have her revenge. FL pretty cuckoo and cunning, uses her assets to her advantage.

FL gets teleported to another world and now has to act as the Duke's fake lover to fish out the rats that dared to kill someone in his area (it was a prospective fiancee but no feelings)

MLs are all demons feeding off a specific human sin. FL is immune to their charming powers and helping(?) ML with having to stomach the sight of blood.

FL in an arranged marriage. They gradually fell for each other but FL is used as the ML's weakness and dies. 2nd life FL is more assertive and chases ML, pretty easy falling for each other. FL intends to take hold of her destiny more securely and not end up as tragic as the 1st life

FL knows how to charm people w/ her sincerity (especially females). wFL loves FL and outright rejects the Welsh (they're all awsholes, crazy, and seems to just want to possess her like an object).

FL has to collect hatred from multiple characters. ML is also a system host who has to complete quests which are related to FL's. FL only cares about food (though she can be quite sentimental at times)

FL is a war hero, ML is a warlock. FL had a one-night stand w/ her childhood friend. She's pregnant and she wants to have the baby. She runs away as she asked if ML still hates children and he answers yes; she's afraid he might do something to her unborn child.
