The biggest obstacle for Tittyko is acknowledging that she drains other people's fortune for her selfish personal gain, it's not a matter of being better than others. Look at her inner thoughts at school, she doesn't respect ANYONE at all, except for the butler.
If she doesn't learn life lessons the hardest possible way, she will never change.
As for changing to normal, I'm betting she will transform in front of his hazy eyes and he will think something shitty happened to him (Tittyko happened).
