https://www.mangago.me/read-manga/hate_girl/ (pretty new so you might want to let it marinate)
https://www.mangago.me/read-manga/but_please_help_me/ (a but different but still a good angst)
https://www.mangago.me/read-manga/july_found_by_chance/ (this is a slow burn angst but in a different way so I still wanted to recommend it)
https://www.mangago.me/read-manga/kakao_79/ (this was also isn’t exactly like that but one of the longest slowburn ive read)
https://www.mangago.me/read-manga/gradually_close_to_the_heart/ (this was a cute read)
https://www.mangago.me/read-manga/perfect_relationship/ (This one had a really interesting concept? it’s completed on a different website)
https://www.mangago.me/read-manga/my_husband_who_hates_me_has_lost_his_memories/ (havent got around to reading this yet but seems alright?)
https://www.mangago.me/read-manga/among_the_filth/ (havent finished but angsty also dont like the ml that much)
https://www.mangago.me/read-manga/there_were_times_when_i_wished_you_were_dead/ (now the ml in this was pretty hard to like ngl)

I want preferably straight non fantasy romances (isekai without magic is alright) where the ml hates the fl and maybe even likes someone else. And the fl who likes him slowly distances herself and then be falls in love and pining. But I want the fl to end up with him not someone else.
