Probs not it but "revenge wedding" has a similar trope in it so it could be worth checking out?
I raised my fiance with money?
But she's silver haired https://www.mangago.zone/read-manga/the_princess_doesn_t_want_to_be_spoiled/
y’all i appreciate the help like ily but it isn’t any of that the FL is an annoying brat and the ML just puts up with her kinda thing till later on she got character development? also it isn’t a reincarnation story. i swear i’ve read it somewhere and people was hating on FL (my brain cells are loosing i’ve been looking through at least 20 sites now)
"My royal marriage" is the only one i've read which doesn't fit the reincarnation trope.
https://www.mangago.zone/read-manga/save_me_princess/ i never read this, but i VIVIDLY remember it solely bc of how much the commenters HATED the mc for being exactly how she was intended to be written (spoiled)
and maybe this https://www.mangago.zone/read-manga/i_m_the_ex_girlfriend_of_a_soldier/. idk if ppl rlly disliked the mc, but i remember a few ppl disliking her for some reason
it’s a historical one where the Fl is a typical spoiled brat but got forced to married the ML who wasn’t rich?? idek i’m forgetting bro. she had blond hair and the ML has dark hair y’all i’ve been looking through all my bookmark and reddit but nothing helped
