I'm glad the author shown Teru-chan as a great and proper teacher. all this time, she is basically function as jokes material. either she is fear of Nako-chan (she think Nako is a delinquent) or when the students just leave her alone during holiday. but this time, Teru-chan really act like proper teacher. she gives advice and support for her students when they deciding their high school. and she even promised to help Nako to preparing for entrance exam to the same school with Bocchi. I like it so much!
