hmm just trying to connect the dots here, feel free to follow up if you want:
so the guy who abducted her and raped her was that 31 y/o dude who was arrested, but the brother also does the same to random girls? did he do it to Mizuho? does the mom knows? did she go to the doctor to check for STD's? does she remember the raping but fakes ignorance? didn't Adam Sandler made a movie with this same plot without the rape?
