Now, I understand that hime can seem way to distant from player character. Which is understandable, she spent 10 years without you. And no matter whos fault it is, it is Keroses, she still missed you and she can't be hellped to feel like she feels. Still , as you noted, her being distant is here being more extreme version of Kiyoko. Sickeningly polite and well meaning to everyone, but only really opens up to her consort.
Now, I do have problem with how we got to that point, but I never got the feeling that she hates us. She just treats us like everyone else. I think that even our character notices how on to prestigious she tries to make herself to be. To the point, that when she yelled at as, their first reaction is same as mine "that is my girl". I think that is going to be one of things addressed in her quest line. I at least hope it will.
