So, it is a classicAnd Ayakas issues, it's bit both. It's part of the "game of nobility" trying to get the favour of the Emperor to get status so she can do what she wants, to a point. And to get away from her family (mostly father) so she doesn't need to be subservient to him. Being a mage cut that tie, but in her foolishness of wanting a title she made herself subservient to him again while she is on his land (rank thing). And because of the family tie and the rank, she can't ignore his summons or it would look bad on her. It is a glorious cluster fuck that she created because she had ambitions to rise above her original status.

? However, I hope, that there will be shed some light on her father past. If he was a different man back then, why he decided to send her into monastery? Or perhaps the decision was made after the change? Also, it seems, that this family have a harsh legacy (seeing, how their land was cursed), but again, in such case, her father seems to be different at first. Different enough, that lady Miki had feelings for him (and she, for sure had much more freedom in such regard, than any other noble because of her nature, even if it stayed hidden). That brings a question, if Ayaka path was set in stone or it could be different, if her father would resist the change to the worse?
And, perhaps a coincidence, but a good man gradually turning to the worse, in the shadow of coming alignment? Could it be somehow related? Was the change of his choice, or some powers were nudging, gently pushing him in that direction, step by step, over these years?
