If they took Halsin, the drows, Mizora, all that optional content out of the game, SH is shown as being naturally monogamous throughout her whole romance with the player. Just because the player has the option to make her join a polyamorous/open relationship doesn't mean she is written to be like that normally.
Sure if none of it existed you'd be right. But it does exist, and that allows what I said to be true. And I will never agree those choices should be wholesale removed from the game. I would much rather they finish developing the dynamic to be better. This is of course still with exception to Halsin whose behavior if you turn him down is unacceptable and needs to be adjusted.
