I really shat bricks while watching the preview of ep 12. Didn´t you guys get it? No.4 is not asking Hiromi if he could kiss her , he is asking his damn own sister Noe! To ease her pain maybe. It´s now damn sure we get the Hiromi Ending and maybe some little Incest service. But to be honest if I had a sister like Noe i don´t know what I would´ve done.
