During the 'lockdown',as Rin calls it, Rin, Kai, Penny and the princes have their studies together in the morning. After lunch, Rin, Kai and Penny will go exploring and sometimes Violet will tag along.
And after dinner, the families will sit together and play games. Usually, the king doesn't have time to play with them but when he does, he will be there.
According to Rin, this routine is fun except when they have to learn. But other than that, it was fun. Prince Kai, on the other hand, thinks that the routine is boring and is a little bit jealous of Violet because she gets to spend more time with Rin then he does.
