I'm not caught up to Naruto, but I know what happens. I'm just wondering what you meant by saying Sarada broke the shounen law of boy vs. boy law?

It’s kinda typical for the main protagonist to go on against another male protagonist/antagonist/anti-hero for a long while. An example is Goku vs Vegeta, Naruto vs Sasuke, Ichigo vs Ishida, Natsu vs Gray and so on.
Boruto and Sarada would be one of the few examples who broke that rule.
