“My Body Has Been Possessed By Someone” right?
https://www.mangago.me/read-manga/my_body_has_been_possessed_by_someone/ definitely (I remember the cover you're referring to, it was probably the novel's)
Fl is on the cover with both of her red haired brothers and father. She makes medicine and helps the queen when she ends up all itchy, brothers mistreat her and even her supposed fiance with white hair doesn’t care for her. According to rumors she ends up with her dad lollll but I think it’s a loop regression or something like that
