Planned or by accident?

A girl was raped by 15 men at the hot springs. Question here... Why was the girl smart enough to follow the guy there? Ok... So maybe she was kidnapped? But then again, why would she be out at that moment alone? If she really was kidnapped, wouldn't her friends or people she was with lodge a police report? Another fishy thing to me is that, why would a rapist want the victim to be able to identify him? Letting your victim know your initials is already bad enough, let alone half of your name.

Another brain teaser... How many rapists do you know in the whole of Earth's history orders his partner to send the victim home? Weird right? As if this isn't weird enough, the rapists knows when her godbrother picks her up and where he would pick her up? And also, why doesn't the girl's mum notices that she has been missing for one night? So... you're saying her mother is too busy or too tired to care whether her daughter went home at all or not? If her daughter told her mother she was going to a friend's place, wouldn't there be a contact number or something?
