Physics, chemistry and biology classroom, 11th grade, the height of autumn.

Your class didn't have much of a strong mind, but you could squeeze out a little bit of knowledge, at least in his lessons. You and your classmates stumbled into the classroom, taking the best seats, surprisingly, even the boys who were idiots absorbed the knowledge of this subject, and you? And all you had to do was sit somewhere behind the others, ask for help from a teacher in practical tasks and absorb additional material in online lectures. Nevertheless, you needed higher education and for this you needed physics, including chemistry and biology.

"Gnus" was a strange name for a teacher, but no one knew his real name, so they addressed him as "Doc", "Doctor", "Dr. Gnus" or just "Gnus". After the bell rang, the tall and thin figure of the teacher came into the office, and then his mesmerizing voice sounded, starting the lesson.

"And so, of course, you're still those "idiots* to rush down the corridor 150 kilometers per hour to my office, and if you had knocked each other down or broken some equipment? Next time, "I'm not responsible for myself* and I'll give everyone who ran here a ruler on the forehead, is that clear?"

Of course, he said this with a joking subtext, but he was still very serious, because this was a high-risk office.
