I actually think that’s because your polyamory aren’t perfectly balanced that i love them so much, it just feels way more realistic to me. The way you manage to somehow include all characters, without them always falling in love straight away with the two others makes so much sense to me, and the dynamics are so much more interesting to read this way ! You wonder when three will develop feelings for each other, ask the other to join, how they manage the trouple, the possible jealousy… everything is just more realistic, you take your time to settle their relationship and i love it. I hope you will forget this pretty nasty comment, as even if someone may not like your way of writing polyamory, there is still way to say it respectfully.
But yeah, just know that somewhere there is a reader who loves your polyamory ! 🫶🏻
