At least we now explicitly know her problem: she incorrectly reads her feelings as selfish and transactional instead of mutual desire. And mutual desire in addition to her concern for Xiya’s wellbeing is a good sign. I don’t think she’s dense or stupid. I just don’t think, culturally, she has any concept of what these feelings are beyond her need for mana. It’s like a child going through puberty, but one that’s taught that the feelings that are coming up are something completely incorrect, and that was never corrected as they grew older.
