Because it's basically reverse rape. I mean, he was completely innocent. and they keep abusing and taking advantage of his naivete. Frankly, it's disgusting. Imagine if this is reverse and the mc was a girl. It's not okay, just because he is a boy, and doesn't understand that he is being taken advantage of. It was such a good story too, such a shame. It's sexual abuse people. He's 14 but honestly he more like 5 when it comes to sexual relations and they are taking advantage like predators.
