Sensei knocks on Rin's door while she's getting dressed, and has to decide whether or not to "be good for once" and wait outside until she's ready. Futaba is staying the night with a friend, and when Sensei wonders where she is, Rin jokingly asks if he has fallen for Futaba. She talks a bit about their relationship, calling Futaba her "borderline-sister". Sensei suggests that he could stay overnight in their dorm room, supposedly for the sake of scientific experiment — an explanation which Rin calls "totally believable and not-at-all unusual". Sensei tells her that he really wishes she were more naive sometimes. Rin says she's is feeling a bit tired today and wants to sleep, but suggests they watch movie with Futaba sometime.
