I was able to save up money for my release
What will you do with the money you have left over?
I'm going to purchase my female servant with it
That's great that you are working hard to save money for the things you want, but are you implying that you want to buy a person?
There is no point in surviving if there is nothing left to live for. I do everything for the money.
I hope I am understanding you correctly in that you want to hire a servant with the money you earned. As long as you are hiring someone and compensating them properly, it should work out just fine.
