Sensei goes to Rin's room to hang out. Futaba isn't there, and Rin asks Sensei if he has acted on the tip she gave him about Futaba's feelings. She also reports that Haruka showed a lot of interest in him, despite being married. Sensei thanks Rin for the information, but says that she seems weirdly keen on trying to hook him up with people. He finds her denial unconvincing, but doesn't press. Changing the subject, she asks why he became a teacher, and guesses that wanting a harem of girls is closer to the truth than his actual answer. Her comments imply that she wouldn't mind having the same thing, and Sensei asks her if she's a lesbian. Her answer is "Yes. Kind of. No.", which she clarifies to mean that she's bi, but thinks girls are definitely better. She asks him not to talk about it with other people in the class.
