hello ! so i read this manga awhile ago so i’m sorry if my description of it is a little off :/

anyways, it’s about a girl (who is in highschool i believe) and well she gets this fiancé who she doesn’t really want at first. i also think she lives in a world where the women are more in charge than the men (or maybe that’s where he is from?) uhh, i also remember at one point she has to like fight for him in front of his family and maybe like his village people? i think she has powers of some sort to use against the other girl who wants her fiancé!

i think he has long hair? one of them has pink or purple hair i believe. i know it’s an older one and i think the art style is upgrade during it?

Just a wild guess here but could it be Operation Liberate Men ?

thank you but no ! i actually found it on my own from going through completed manga ! it’s tian Jiang Xian Shu Nana
