I was thinking that nakajima was not a fool for making a smart move against katou but why the why you told everything to that crazy girl and expecting praise from her! She is not right in the head, i don't even know whether she is a sadist or masochist.
@piracyknight I doubt he told her, she probably just figured it out along the way, also I think she's the ultimate masochist. She loves and looks forward to any pain and torment you can give her, while also forcing any guy to be her dom.
