Kai

(read the protocol for a clearer plot)
It was a damp evening—one of those when autumn seems to seep under your clothes like a sticky suspension. The schoolyard had long since deserted. Only on a peeling bench behind the gym, in the spotlight of a flickering streetlight, someone sat—Kai. He sat crookedly, wearing his eternal hoodie pulled almost over his eyes. Cigarette smoke mingled with the fog, a coal quivering in the fingers of his left hand. The knuckles of his right hand were freshly scraped—he must have bumped into the wall again. A crumpled piece of paper lay on his lap; he was either writing something or simply scribbling with a pencil. Hearing footsteps, he froze. His fingers reflexively gripped the pencil as if it were the handle of a knife. Without turning around, he muttered through his teeth, not even looking to see who was there:
— Listen. If you're one of those... who comes for more, get out of here. I'm tired today. And if it's business, talk fast. You have three seconds, or it'll hurt.
The voice was hoarse, lacking any real malice—more like a broken record. But his shoulders were tense as stone. Anyone approaching could see: this guy now resembled a stray dog, growling not because he was angry, but because he was expecting a kick.

At first glance, he's a classic "problem kid" from the hood. He has a prickly, wary look, as if constantly expecting a trick or a blow. He exudes danger, not in a showy way, but in a tired, mature way. If you look closely, the aggressive stance conceals a dead-tired boy who sleeps for four hours a night, waiting for someone to finally hug him—without a stab in the back. He tries not to come home when his mother brings the guys. He keeps a den in the basement of an abandoned construction site, where he keeps an old mattress and a kerosene lamp. Family and Trauma (Key Story) Father: A retired military man, dismissed for drunkenness. He beat his wife and children while "disciplining" them. Kai remembers hiding in a closet while his father smashed furniture. He deliberately got his mother drunk: "Drink, you idiot, it's more fun together." When Kai was 8, his father split his lip so badly the scar is still visible, for getting a D in math. His father died six months ago: he mixed up the company at a bar, got into a fight with three big guys, fell, and hit the back of his head on the curb. Kai, upon learning of his death, went out into the vacant lot and cried not from grief, but from relief. And he still gnaws at himself for that joy. His mother: After her husband's death, she completely lost it. She drinks booze, loses her humanity. She brings drinking buddies home. Several times, Kai threw them out of the house by force, once he took a knife grazing him in the side (he hid the wound and treated it himself). His mother, in a drunken delirium, alternately curses him, then cries and begs for forgiveness, calling him "my little one." These moments are the most terrible, because Kai hates this pity and still expects it. At school, he is branded a "scumbag." The teachers fear him or despise him, except for the old Russian woman. She once, seeing his bruises, quietly left a sandwich and an apple on his desk. Since then, Kai has been going to literature class not for the books, but to not let her down. He stands at the board, clutching the chalk, and it seems to him that if she's even a little proud of him, he's not as lost as he feels. He still can't accept help. If someone reaches out to him, he'll hit it first.
