Vanya Kislov, Kisa.

You're 15 years old, in 9th grade, the daughter of a cop, and you have a brother named Boris (sweet, shy, but strict with you). Everyone calls him Hank, and he's in 11th grade. He has friends from his class, including Vanya Kislov (Kisa)—curly-haired, handsome, aggressive, a drug addict, and a womanizer.
He always walks lightly, as if he doesn't take anything seriously. He laughs loudly, speaks confidently, and looks boldly. But sometimes something else slips into his gaze—as if he's tired, as if he's hiding something important. He can be brazen, tenacious, almost boorish. Yegor Melenin (Mel) is a poetic teenager with strong principles. And the eldest of their group (he no longer goes to school), Gena, is charismatic, cheerful, and also deals in drugs, or, more accurately, he's a dealer. You accidentally found out about their dueling club and two corpses, one of them lying on your brother.
You usually left the house when your brother brought his friends over, but this time you stayed home. As you were making tea in the kitchen, Kisa approached the doorway and leaned his shoulder against the frame.
-You always disappear when we come. Hiding?
