interesting ask! the closest i can think of that ive read is this > https://www.mangago.zone/read-manga/exclusive_no_love_zone/
the main conflict stems from the fact that our main character thinks the alpha love interest should go on happily without him and marry an omega. its also a really funny & surprisingly has incisive sociopolitical takes on omegaverse

ohh i just finished reading this theyre the opposite of fated mates lol https://www.mangago.zone/read-manga/salvation_spirit/
it’s a bit dark though and we still dont know if theyll end up together

Anyone got any recs for stories where the main characters aren’t soulmates? Like, they actually fight against fate?
