Nana and Rino were obviously learning their way on royal duties as well. But compared to Kaoru the two of them were much more serious. For Rino it was considered normal, ever since they woke up he was the one who diligently studied and trained.
What shock everyone the most was Nana, she had somehow became much more quiet and started learning diligently. People would sometimes speak among themselves.
"Was she possessed by princess Eureka?"
"Did the real princess Nana disappeared as well?"
"Did she hit her head somewhere?"
And the likes. But of course they never said it out loud, for she was still the princess. They were just baffled, what had happened to their playful princess? The only time they saw her become diligent was when she had a fight with princess Eureka.
Yet even during that time she still had times where they would hear her complain about how difficult it was.
