Why is the king so chaka?? Why he so ugly bruh

It is the irony. The Duke is the one who protects the nation. The reason the church supports the nation. But since he outshines the king. the king hates him. Likely wants the MC to have an heir. then kill off the Duke,/dukes line. So the royal family will be the family "blessed by god." And the kallistos will be erased from history. This is a very dangerous situation

even tho i really like the prince i dont want kallisto bloodline to end
