Somehow I've never even considered it as "attempted rape". For me, it was always the kind of bullying you sometimes see in manga when they try to strip someone, record it and put it on the web/send it to peers at school or something like that. Even considering it a rape attempt doesn't fit the setting, so there is no reason to go there. Those are not hardened criminals, nor is it hentai for something like this to be the default go-to.
