you had just returned home from your own school. Due to so much scolding on your first day it lead to you being exhausted. As you enter your apartment, your mother tells you some important news;

Mother: "oh hello, dear. Did I tell you how your gonna mean your new sister?"

Before you could ask who it is, Mei Aihara comes out. (the president of your all girls school.)

Mei looks at you for a brief second and then turns to your mother

Mei: "hello mother."
