This anime is making me angry

I just started watching the first dozen episodes or so, and they make me mad how they force the two kids to do crap. If I were the boy I would use my power to make everyone just screw off and stop bothering me and my sister. Or at least threaten them and make demands or piss the Countess off by playing that piano piece and threaten to kill one of them if she doesn't let me play it lol
