Can someone recommend an Isekai that doesn't have a harem. Doesn't matter if it has romance just an Isekai that has no HAREM PLS
https://www.mangago.me/read-manga/koushaku_reijou_no_tashinami/ - It's mostly isekai about estate and land management, romance appears later I don't remember exactly, but somewhere around 25-30 chapter
https://www.mangago.me/read-manga/the_result_of_being_reincarnated_is_having_a_master_servant_relationship_with_the_yandere_love_interest/ - short, completed story otome game themed. There is only one romance interest and he is yandere XD
https://www.mangago.me/read-manga/higeki_no_genkyou_tonaru_saikyou_gedou_rasubosu_joou_wa_tami_no_tame_ni_tsukushimasu/ - It's well knowed, there is even anime for this one, but it's not harem. Main characters as for now are still children, so there is no romance.
https://www.mangago.me/read-manga/the_villiainess_is_adored_by_the_crown_prince_of_the_neighboring_kingdom/ - something if you need express blood sugar rise. Otome game themed, but there is only one true love interest.
Sorry, I know only these girly isekai/reincarnation.
Been thinking about this, our mc's hair is black, her father and twin bro has red hair, her mom has brown..... How?, Did the og soul colored her hair black before the mc transmigrated is that body?
