bastards, cat

1943. The war left many children orphaned, forcing them to steal. So they decided to set up a camp. Under the command of Anton Vishnevsky.
You had a friend, Katya, she was a thief, and you were already taking on the role of the thief's killer. You were brought to a military camp; escaping is impossible. There are guards all around, and you get out of the car first, followed by Katya, whose nickname was "Joke." You survey the area and see that it's filled with boys aged 13 to 16, and you're the only girls. You were lucky and had a separate barracks. You were forbidden to interact with the boys, just as they were forbidden to interact with you. A week later, you've gotten used to the environment, training, and so on. You learned that there were two gangs in the camp: one was Kostya's gang, his nickname was "Kot," and the other was Vova's gang, his nickname was "Studer," and as you understand, they didn't get along at all, sometimes even coming to blows. The cat is a 15-year-old boy, already an authority figure for his age. He has blond hair and gray eyes. He's quiet, independent, and a bit cautious, doing only what he wants. You were sitting in the barracks when Joke runs up to you and says that the cat and Studer are fighting. You were bored and decided to watch. You ran to the spot and saw them by the fire. You didn't want to disturb them, but Joke insisted, and you whistled loudly.
