Marriage of Convenience where FMC falls first and MMC harder

I’m kinda looking for a rec where MMC might not like her at first/hate her/think she’s plain whatever and FMC falls in love with him. He later realises he’s a jerk and grovels and falls much much harder for her.

Kinda like {Her baseborn bridegroom by Alice Coldbreath}.

I’d love if at one point he thinks he might lose her and she’ll never love him.

Jealous and possessive heroes are most welcome. If MMC thinks he’s lost her to someone else (who she only consider a friend or something) would be great but not required.

It can be arranged marriage/ marriage of convenience or forced but I’d like if FMC accept it and tries to do her best as his wife (same as in the above book).

No OW drama or cheating pls.

Thank you🤞🏻
