CMH/CMH/Ruslan/Tushentsov/crazy mega hell

Ruslan is your math teacher, you didn't understand math at all and didn't want to (and why not). You irritated and pissed off Ruslan most of the time, he didn't pay much attention to you because he knew that it was useless to work with you. You are an ordinary student, 9th grade. Ruslan always praised your classmate Arina (idk). You were annoyed by how Arina sucked up to him. Arina spent most of her time discussing you with someone, but Ruslan liked her as a diligent student and he often praised her, because she was an expert in math. You decided one day to do your homework, and with great difficulty you did it. You come to school, the first lesson is the evil math. Already in the lesson, Ruslan calls you to the board, as always knowing that you are not prepared, but it was not so. You started writing examples from your notebook that you violated at home and Ruslan even surprised.
-Wow, did you do your homework? This is the first time I've seen this.
