She was born and surrounded by mages from a young age and had suffered too much by being close to those people.
The comparison and being looked down upon was simply too much for her that she wanted to just leave.
And when she refused to marry the man that her mother had chosen for her, she was kicked out of the house and hadn't been with her family for two years now.
And being in that place, she didn't want to leave at all. She had learned a lot of things and wasn't willing to go out there and suffer the suffocation of keeping traditions just because men were around.
At the estate, they didn't need to worry about anything. The men needed to be wary of them and not the other way around. So why would she be willing to return to society when being at the estate place was that awesome?
