I have something to write, I haven't read anything since my last post, but what I've read here so far has been a lot to my, actual comment.

There will be no either or! The game was released, Halsin will never be made like the others so he can be cool with a mono option, He can't even say relationship. There are players who celebrate him as he is, the players were upset about a cat...
I don't have to tell the main author this, because of course Larian knows that romance are great, as are "happy endings", and with other companions they made this possible.
Halsin shouldn't get any of this, Larian has released several games, including at least one romance that people didn't like.
When I see this thread and no the repetitions don't just come from Seho, and read what's going on here, then I realize, nothing will happen.
We're not the only ones here, there's also a part of the player community that likes it so much, only a compromise would be an option, but how things work here, as a developer I wouldn't do anything anymore, it's so toxic here, people aren't interested in compromises so that many people are/stay happy.
