I seriously hate the king!!
And even the way they somehow try to redeem him doesn't makes much sense.
He is supposed to care a lot about his family but he has several mistresses and consorts and 7 kids!! Wow, does it makes any sense??
It only means he actually doesn't give a crap about the commoners. He is supposed to be wise and quite good in magic. He has an amazing butler, he is the king, yet he couldn't figure out how the mysterious disease is infecting the royal family??
Now, the author shouldn't have tried to redeem the King and mentioned that he was a hypocrite, because he is.
Setting the KING ASIDE, the prince is really likable. SO I give it an 8 (-2 due to trying to redeem the hypocrite king)
