I think it was called Jealousy.
I checked the ones with 'jealous/jealousy' in the title, it's not. Thank you for helping tho

So there is 'Fuck Buddy' but it's not cheating. First 2 men have sex with women, then with themselves and women. But they all agree on that. Could be classified as bisexual, it's not that dark until the characters' past is revealed which could be considered pretty twisted. It's short, so try reading, maybe you'll like it :)

Ah, I already read this one before. It's a good story. This isn't the one I'm looking for, but thanks for helping.
I read the story I'm looking for a long time ago and it had a really dark? Somber? Brooding? Atmosphere? Cuz it seemed like the three of them were in a polygamous relationship - the two of them were okay with it (seme and woman) but uke needed some time before accepting he was likely the only one who had feelings involved in the relationship, one-sidedly in love with seme. He never met the woman before getting brought(? Whisked away?) to that inn-like house and discovered he had a competition to the seme's "heart". My memories are honestly kinda hazy, but they didn't have sex with any other partners except the people in that house.
If only I can remember what the cover looks like, or whether it was a oneshot/extra/spinoff or not. This search would be so much easier.
Thanks for helping! This isn't the one but some of its setting match the ones in the story I'm looking for. :)
Does anybody know a yaoi manga that's kinda dark and involves some bisexual cheating? Like, I remember the setting was on some isolated location as if an inn or resort and there, the seme has sex with uke (main protag) and another woman. The woman knows and accepts that this is all just sex with no strings attached and is very cool with seme having sex with another [male] partner and that they're all living/staying in the same house. Meanwhile uke is hurt because he likes/loves seme. I don't remember how it ended and the title so, if anyone can help me, that'd be great. I don't remember if the woman's face was even shown.
Avoid dj recs/titles.
