I'm a woman, I've only read this chapter, I'm not interested in reading the rest.
And you keep missing the focal point of the situation... this guy, the childhood friend (so, technically a person close to her and she trusts, not a complete stranger), went to see the girl IN HER DAMN HOUSE, and she let him in because she obviously trusts him. They weren't seen in the middle of a forecourt at night, in the park or in a dark alley. She's not the one who went looking for him, showing off who knows what kind of provocative attitude. He went into her house, saw her in a Tank top and shorts - which is very normal clothing, I would say - he got the bone to fly because she is beautiful and shapely, end of story.
But since to the reader's eyes it would have seemed only a filthy pig unable to keep it in his pants, the philharmony started on the fact that "the world is ugly, you're too defenseless, i says it to protect you"
Protecting her a big bullsh*t, is just a way to lighten his conscience by blaming the girl with an "oh, I told you that if you dress like that you risk provoking me. Then don't complain if I get my hands on you and r*pe you at some point, eh? "
