I dunno I feel like sex and romance in RPG's has kinda gone off the rails completely, I don't like how EVERYONE is bisexual ( or even into dragon people and other '' beast '' races ) and worships the ground that you walk on seemingly by default.
I think sometimes not indulging the player actually makes characters and the setting feel more real and believable, it kinda feels a bit like a narcissism fantasy with how it's handled in RPG's nowadays imho ( it's not a personal accusation/ attack, I just dunno how else to describe it ).
I didn't romance Halsin so I can't speak on the specifics, but I feel like writers not indulging the player is actually a good thing because such is life sometimes even if it can disappoint me sometimes too.
I recently played WoTR again and the character I wanted to romance just straight up wasn't into women altogether, was I disappointed at first yeah but I kinda appreciated it in a way because it makes the character feel more real and like she doesn't just exist solely to indulge my fantasy.
It feels a bit more '' adult '' in a way, but I dunno if that's what people really want.
The world and its characters revolving entirely around your character and what you as the player wants is just kinda boring imo and makes things feel artificial.
