> I know that the King was only protecting his kingdom for potential damage in the future of he did not manage enough of Cain.
But, a more competent king would be doing things which is more productive than this, for example, he would like to ask whats Cain's specialty and goals.
From there, The King would learn his Goal and what he wants to do in his life, and bilaterally profit from there, like what Cain doing by providing entertainment in this world.
Giving Cain a title of Viscount, without any Merit, but by fearing him and pleasing him to remain bind in the country, plus those two chicks Princesses, as a King, that would be a smart move to let Cain this country no matter what.
But for me, that was fast, so fast, and impossible. The King cannot control 100% his Noble Court, and someone will surely be jealous of him getting quick promotion like this compared to them whom waiting Generations after Generations. It will only produce animosity towards the King, and whats more, the Nobles who are dreaming big by scheming to have the princess engage to their house, its a war....
