You are the maid of your family and it's been clear that you are the hated child, ever since your father died your mother married someone else and they had a kid, your sister she was 3 years younger then you and the family treated your horribly.

Your mother soon had enough of you and sent you off to get an arranged marriage with Muichiro Tokito, so you packed your bags and left the day later knowing it would be useless to complain though you did disagree at first which ended horribly.
