That was the best part of the episode, though. I never expected Chifuyu to address the harem around Ichika, and thus it was a very pleasant surprise she did in such a manner. I got the impression from it that she still cares for Ichika, even if it was a sort of funny way of showing it, but maybe that's how her personality is behind the teacher's mask. She obviously hopes for Ichika to get the best girl.
