It seems that's the entire plot of the story: Everyone's trying to split our 3 MC's apart from each other, for the sake of their believes, prophecies, power struggle, etc.
On page 12, I know it's just a translation error and it's supposed to say "are your injuries healed already", but the king saying "Zack, you injured already?" is real funny and just sounds like the king's smack-talking him for getting injured so quickly.
Huh guess if a conflict would happen it would be the death of their dad not like he can live forever and no parent wants their child to never leave the nest
