Nice chapter, but this one was very harsh on my boy, I mean...
why does HE needs to say "sorry"? For all is both the other dude's fault for watching porn videos (even though is normal for his age) and her girlfriend's fault for overexaggerating it (pretty sure she looks at other men like any other girl would do, it's also normal). Also, I think the way sensei acted was rude, pretty sure if the genres were reversed and we had a male teacher, he would have to say sorry instead.
