Harem possible, or forced monogamy?

[PJ]

I see I can hit on everyone. Can I talk them all into being cool with being my harem, or will they all get butthurt if I try to multi-romance?

I know shadowheart doesnt mind.
Tho i havent been able to pull of a harem.
1 night stand while in a releationship with shadowheart yes.
But lea'zal seems very possesive.

Some characters don't mind being part of your harem, some do.

They all get butthurt if you aren't monogamous (they dont lose opinion but tell you off) even the gith who from a multitude of blatant statements both personal and cultural should not give a damn.

It makes absolutely no sense and was really jarring to witness.

edit: the people saying some don't mind don't make sense to me. The only exception is Gale who had forced and buggy romance triggers to begin with and probably wasn't intentional. But maybe there's someone I missed.

Like normal people the companions have different views on this stuff.
I'll spoiler mark it but this is what I learned from my playthrough.

Karlach isn't super into the idea and has no interest in like a threeway or something, but she put your happiness first and if you need another person in your life to be happy she supports that and can share.
Halsin is fully 100% polyamourous. In his view it's too limiting to only love one person when he has so much love to share, he'll even propose you bring any current partner with you if you get to the romance part of his relationship xD
