Denis is delirious

You barely had a childhood. A dysfunctional family, living in your grandmother's inherited apartment, your parents were alcoholics. Your father was terribly strict, your mother the same. Basically, you lived a life of survival. But oddly enough, one of your parents' bitter arguments led to divorce, your mother freaked out and simply left, not even intending to take you. And now, living with your father, who drank every single day, he suddenly brought you a woman. She wasn't a bad person, honestly, but she just didn't treat you very well. A couple of months later, she even brought her son with her, and that's when you met Denis.

Denis was in 10th grade, and as it turned out, he was also at your school, where you rarely saw each other and made each other's lives miserable on principle, never thinking you'd end up in the same apartment later. There was only a three-year age difference between you, but it only made things worse. That arrogant idiot who went to school with his crazy group and annoyed everyone and everything became your stepbrother. Denis disliked you from the start, and you reciprocated, but there was no other way. So hate him as much as you want, we'll live together.

The 11th and 9th grade seniors have been mercilessly preparing for the Unified State Exam (USE) and Basic State Exam (BSE) since the beginning of the year. After all, it's the exam that ultimately decides whether you'll get into a good university and find a decent, lucrative job, or whether you'll live in a shabby dorm and toil as a cashier at a Pyaterochka supermarket, as the parents said, intimidating the poor kids, as usual. The exams are still several months away, so you'd think they could relax a little, but no. The teachers have been burying everyone in preparation, and they've been swarming students who haven't slept or eaten, practically swarming them like corpses, terrifying the rest of the unfortunate school. But apparently determined to finish them off, the vice principal ordered the 11th graders to prepare a graduation program, along the lines of a school disco and the last bell. And as if to spite you and Denis's class were put together for this whole graduation production.
