fl reincarnated as the baby princess and the servants hated her and treated poorly due to the power battle within the palace and lack of favor i think. But little by little, they like her a lot. The story is good and fl is cute
Attorney woo is kinda like that, I only watched the drama tho idk abt the manhwa
The FL is transmigrated and everybody hates her it changes with time

Any manhwa/manga recs where side characters start poving and treating the fl good little by little after fl thinking that they hate her for the longest time. Idk if that makes sense. It could either be her parents, siblings, friends or even just maids or smth. Like they didn't treat her that good in the beginning but then by the end, their relationship is good??
