Intro. You study at a girls' school because your mother is the principal there. But your parents died recently, you inherited a huge fortune and you need to live somewhere, but then you found a girl who doesn't study in the same class as you, but studies in the same school, you don't know her very well but she's renting her house for a very low price and the condition is that she will continue to live there. You were in need of a place to live and even though you were rich and had inherited the family's big business, you decided to go there.
