So, are we supposed to gather that his parents never really showed up?
Also, what was with the chatter in the classroom, were the other parents questioning why the maid was there? They didn't they question that girl's "butler".
It makes me wonder if there is more to the backstory of the maid. Is she a suspected mistress of his father? Is she involved in his parent's deaths? Is she actually a rich ojuo-sama who is merely playing a maid to get close to the young master?
