The more i read this the more I wonder if he dressed as a commoner and purposely riled up kids who seemed to be sone kibd of nobility or at least a wealthy family to see how they'd act towards him.
I think he's trying to get the MC to snap at him since she didn't try to hit him or pull the "Do You Know Who I Am!?" Card ect. Yea she reached a bit, but she didn't get violent or try anything other than confronting and than giving up. Since she's mentally an adult, she won't lash out like a child would, and because she humbled herself, she doesn't act spoiled either.
He might be trying to prove all nobility are trash rn, and in the future, the ones who seem to be against him are especially his enemies.
Makes me wonder if he thought Tori was corrupted in the future, but than again he let a princess live before going on a killing spree.
I really hope the Mc doesn't get hurt by him before she has a chance to change him, bc sadly it seems like at some point he'll take it a step further in an attempt to make her snap.
