I've already read it :<<<< but thx for the recommendation!!!

Love Me To Death is peak

D!ckheads in webtoon

Omg we seem to have the same tastes!!! I'd love to find more bisexual poly's or at least love triangles but they're so rare for some reason. Anyway this is what I have:

Bisexual harems with poly or open ending:
https://www.mangago.me/read-manga/love_me_to_death/ (probably the best and healthier example, FxMxM throuple)
https://www.mangago.me/read-manga/camellia/ (from the spoilers I think she has a more platonic relationship with her legal wife and an actual sexual one with her male lover at the end of the novel)
https://www.mangago.me/read-manga/a_lady_s_secret_life/ (!!non-sensical smut)
https://www.mangago.me/read-manga/a_changed_man/ (!!non-sensical smut)
https://www.mangago.me/read-manga/just_hold_hands/ (!!non-sensical smut)
https://www.mangago.me/read-manga/heart_throbbing_conqueror/ (there's one female love interest and a cross-dressing ml in her harem)
https://www.mangago.me/read-manga/otome_game_no_hametsu_flag_shika_nai_akuyaku_reijou_ni_tensei_shite_shimatta/ (a classic. no idea if there's an actual endgame here)
https://www.mangago.me/read-manga/for_the_happy_ending_of_the_tragic_novel/ (the saintess is one of the love interests, open ending but it's pretty obvious she'll get with a male lead)
https://www.mangago.me/read-manga/what_happens_when_the_second_male_lead_goes_on_strike/ (arguable LMAO I finished the novel's main story a while ago and I'm personally convinced it's a platonic throuple)

Love interests of both genders BUT monogamous ending (most of these with a ML):
https://www.mangago.me/read-manga/the_prince_of_myeolyeong/
https://www.mangago.me/read-manga/the_pet_of_the_villainess/ (this one made me so sad!!! I wanted them both as the endgame :()
https://www.mangago.me/read-manga/the_second_male_lead_is_actually_a_girl/
https://www.mangago.me/read-manga/fight_like_a_girl/
https://www.mangago.me/read-manga/mikazuki_mao_can_t_choose_a_gender/
https://www.mangago.me/read-manga/wistoria_s_wand_and_sword/ (I'm still letting this and its anime marinate but from the spoilers there are at least 2 male characters in love with him, even though the FL is clearly the endgame)
https://www.mangago.me/read-manga/ao_no_flag/ (spoiler! apparently straight but plottwist gay ending in like the last panels)
https://www.mangago.me/read-manga/saikyou_no_kurokishi_sentou_maid_ni_tenshoku_shimashita/ (only because her/his (probably dead) ex lover was a woman. I still highly recommend the novel though)
https://www.mangago.me/read-manga/surviving_in_a_harem/ (it's comedy, he transmigrates into a shoujo protagonist with a male harem but he already has a girlfriend at home)

Omgggg ty!!!! You're actually dropped a holy grail!! ε=ε=(ノ≧∇≦)ノ I can't thank enough (≧∀≦)

You're welcome :)))
