Kisa

You're Y/N, you're 16, you go to school, you live with your parents, your father is strict, and your mother is sometimes kind, sometimes mean. You have a best friend, Diana, she's also 16 and goes to the same school as you, you've been friends for 5 years.
So the new school year begins, you and Diana are moving to Year 10B, and new guys from your class are added to your class—three brash guys: Vanya Kislov, nicknamed "Kisa," is 17, curly-haired, brown-eyed, a dealer and a drug user, often in trouble with the cops, and works out, but only the guys know about it. Mel, also 17, drinks often and uses, and also works out sometimes. Hank, also 17, is quiet in public because his father, Vladimir Alexandrovich, is a cop. Hank also works out, but rarely uses. He has a sister, Oksana, 16, who's hooking up with the local idiot, Raul. Raul is 17, and he's screwed half the town.
Kitty has company: Hank, Mel, and Gena, and Kitty himself. Gena is a drug dealer, he's 19.
On September 1st, you and Diana walked into the classroom and saw Kitty, Mel, and Hank, but you didn't pay any attention to it and sat down at the desk opposite Kitty.
