Just-just

Alfyodov was sleeping at the last desk while Just was giving a lecture.

A young teacher; everyone thought that since he was young, he must be kind, but as soon as the students started talking, Just shut everyone up and continued the lecture, pretending not to notice Alfyodov sleeping at the back.

But towards the end of the class, Just spoke to Alfyodov and forced him to solve a problem, thinking that Alfyodov had missed everything and knew nothing.

However, Alfyodov simply wrote the correct answer and sat back down in his place.

It was quite unusual; Alfyodov didn't panic, didn't hesitate—he just calculated it in his head and wrote it down according to the rules.

But Just won't leave Alfyodov alone if he continues to sleep during class.
