Damn, I laughed so much at that ending XD. I really like that they're giving the teachers actual personalities instead of just having them as background characters.

It gives the anime so many more funny moments, +1.

On top of that, in this episode, we see that it seems like Oota-kun is starting to understand Kashiwada's emotions—like when she's scared or when she's actually laughing.

It's only a matter of time before they keep getting to know each other and continuing to live more high school adventures.
