The king is just a decoration atp cuz wym you cant control the rumors that the duke spread about your son he's not even trying to do something he just visits and acts like he cares bro and acts surprise like he didnt know what really was happening just earn money and leave the family
Its explained better in the novel but essentially he's a king with no backing, so hes current in an unstable situation. He only ended up there because all other heirs apparent died. The court is now split between two Dukes who hold more political power.
This is also why Arsha is in a weird predicament.
What chapter in the novel is chapter 25?
Ch 58
