For some aspects of the story, sure. I don't think that is the case for Lyria.
Mystic can correct me if I'm wrong on any of this but, I think he weaved that tapestry pretty damn well.
Look back to the first trip MC and Lyria make to the desert and stop at the tavern. The first mentions are of how disgusting she finds the place to be. She's simply not cut out to be in a place like that. Once they sit down, almost the entire conversation is about her breed of elves and their chosen deity. She's real light on the why and how but, real heavy on conviction that her deity good, Eris (the sister of her Deity) EVIL. Not good versus bad or good versus not quite as good. It's all or nothing in her mind because that is what she is raised to believe without question.
Fast forward to Aria and MC going there and you'll note that Aria isn't fussed one bit by the place.
That's the primary conflict for Lyria. Her world view is based on an ideology that fits with what she wants the world to be. You aren't moving her off of that hill. She'll rationalize the fuck out of anything and everything to avoid anything that conflicts with it. The MC knows her well enough to understand that pretty damn well. Explaining isn't changing anything and neither will trying to ease her into shit. Keeping her away was the best solution for her because it allowed her to live in her delusion of was/is. Now, the MC is just too considerate of her to boot or behead her.
Players want to rationalize along with her because elf pussy. Mystic is telling a story of a Deity and her apparently affection for a man that dates back for more than one thousand years.
