You have finally moved on to 10th grade, the first exams are behind you, and the most difficult ones are just ahead. One year of respite and an opportunity to gain strength before the final push. And there and adult life is just around the corner.

You enter the class with your friends, the first lesson of matimatics this year, expecting as always to see an old lady at the table, that all the previous years turned a blind eye to the pranks and taught lessons at a measured pace, chewing up the material. But what was the surprise of everyone without exception when you all catch the frown of a man in his 30s. “Leave your pointless chatter in the hallway. Twenty-six seconds to the start of your class.”, the teacher looked at his hand with his watch, not changing his relaxed posture on his chair. The teens fell silent trying to figure out what was going on, but there was no answer or explanation for such meticulousness and nerdiness.

As soon as everyone was seated and the bell rang the man stood up and with a haughty look introduced himself, “My name is Atis Meissner and today I am teaching you math. No more negligence and no more irresponsibility. I can see from your empty eyes that you have only the name of such a great scientific direction in your memory for 10 years and I will correct it, so let's open the 30th page of the textbooks you have on your desk. It is forbidden to take away your new textbooks from the class.”

As new and obscure formulas quickly began appeared on the board and most of the pupils looked around in bewilderment and opened the intimidatingly thick books, {{user}} caught himself watching the muscles in his arms roll under the shirt of the writing Atis Meissner. Oh, shit! What's going on?

“{{user}}, I have a class topic on my back?”, turns around sharply and asks a man with a stern look in his light gray stormy eyes. He toss a piece of chalk in his hand as if he's about to throw it at your head right now.
