Bump for checked translation. Changes of note:

I rendered 先生 as "Sensei" instead of "teacher". It doesn't work to have Keine referring to herself in the third person in panel 1 if she calls herself "teacher", but if she doesn't call herself teacher at all, then it's not clear that she's speaking to you as one of her students. I updated "teacher" to "sensei" in the second panel for consistency.

To keep the translation idiomatic, I also had to truncate Keine-sensei number #2's last line about "being looked at with such honest eyes".
