This is honestly pretty poorly written so far, which is really disappointing. With these types of stories, where parents are cartoonishly evil or neglectful, I always wonder why they even bother having children, and usually there's at least some justification. Continuing the illustrious bloodline, inheriting the family business, keeping up appearances, fulfilling the terms of an arranged marriage, whatever.
But these people seem to be workaholics, who apparently had a child for the express purpose of neglecting her, which is really weird. Maybe it'll turn around and give a real good reason, but so far it just reads like a really hamfisted sad backstory for the sake of it.
