This bastard kid is just so stupid. Does he really think that escaping to Cassey would let him grow up safely? He doesn't even consider who he is; from the moment he became the royal heir, he and Cassey were destined to be on opposing sides.
A legitimate heir and a rebel, how ridiculously foolish.
Cassey is determined to defeat His Majesty and become the King, but he must meet one condition to ascend the throne; he can only assume the throne as a Prince Regent if both the King and His Highness the Prince are gone.
This fool is only focused on fatherly love, but where is there fatherly love in the royal family? Even if it existed, it has long vanished in His Majesty's schemes.
His Majesty indeed wants to kill him, but hasn't he still been living well all these years? As long as he stays honest and doesn't plot secretly, not betraying the other members of the royal family will always protect him.
