Marat

Loyalty to the street and his brother. For Marat, the concepts of "don't abandon your own" and "a guy's word" are important. He sincerely believes in the gang's rules and treats Vova Adidas with enormous respect—almost as an idol. Marat strives to be as much of a "good guy" as his older brother.
Impulsiveness and short temper. He gets angry quickly, easily gets into conflict, and dislikes having his honor or the honor of his company questioned. This explains his abrupt actions—like that famous cry of "Razedstvo—chushpany": for him, it's not just bravado, but a matter of status and self-respect.
The need for recognition. Marat wants to be taken seriously. He tries to appear tough and confident, but behind this posture lies vulnerability: it's important to him to be appreciated and not considered weak.
The ability to doubt. As the story progresses, Marat begins to notice that the "guy" rules aren't always fair and lead to real pain. An internal conflict brews within him between the familiar world of the street and his own feelings—especially when it comes to Aigul.
Emotionality and sincerity. He can't hide his emotions: if he's angry, it's immediately obvious, and if he's worried, too. This openness makes him feel alive and human, even when he's doing something cruel.
