Well..I guess there goes my theory that the White Cat House Mistress actually loves the Black Dog House Master....I guess she could be divorced from Ameri's father..but I think this makes their secret love less likely.
I thought something was odd when Ameri mentioned her "mama is strict" in the last chapter. It's also kind of weird for her mother to say "call me house mistress when we are not at home"....you both live at a Boarding School, so isn't that your home? Or do both of them actually live in the same room in the Boarding House?
