This is where the stories that society tells, are shown for the lies and often reversals they are.
The stories say that girls are valued, that rape is a terrible crime, that girls must be protected at all costs, they are vulnerable, moreso than boys.
The fact is that girls are not valued, rape is not that bad when it actually happens (each case seems to have reasons to minimise), that there's no interest in protecting girls, and boys are generally more important and protected.
What the stories + the truth do is paint field as weak, and reduce their freedom, while doing zero to actually protect them.
This is patriarchy 101.
Appalling the form teacher who was worried about the situation was not aware of the boys situation. But that's always the way again isn't it. Boys and men must be given the benefit of the doubt, warning girls or women is not fair on the men and boys, it's assuming guilt etc.
The teachers could have been at risk too depending on his size. The female ones I mean.
