One possible plotline could be Viserys facing challenges from within his own court. Maybe there are lords who secretly oppose his rule and plot against him.

Also, his personal growth as a king, learning to make tough decisions for the good of the realm.

Viserys is the main one, no doubt. However, in some stories, there are characters like a powerful sorcerer or sorceress who either helps or hinders Viserys.
