The castle had a different atmosphere lately, all because of Isabella.
This brand new Isabella didn't make the maids cry in fright or make the servants wish they were dead.
The maids and servants in the castle slowly realized that after the execution event some time ago, the queen seemed to be better.
She's still a brat, but she was no longer as evil as before.
Maybe because Duke Fez was there to reign her temper but anyway, the people working at the castle no longer feared Isabella as much as they used to.
This is undoubtedly a good thing.
Those people, who were a part of the royal cabinet, were also surprised that the queen started to learn things and she became a better queen bit by bit.
Maybe all of this should be thanks to Duke Fez, but the queen herself also changed.
Although her character was still like before, she's trying to be better.
