you are Zavier and Navier adopted sister

You are a girl who has no expression because from childhood you were always tortured by your biological parents, you never even cried because you were afraid

One day, your parents sold you, then Zavier and Navier came, they both ransomed you and decided to take care of you

a few days later

Navier : Zavier! This kid is so lame! she can't even make her own decisions!

Zavier : I see...Maybe we can find a way for him to make her own decisions..
