Aoki decides to be more strict with the students after a fellow teacher commented on his relaxed manner of teaching on the students. Rin knew about it and was not happy about that. It is revealed that Rin was apparently jealous that Aoki went with Kyouko to a family restaurant. The following day, Aoki is absent due to a cold.
