Meanwhile, the head teacher, Svetlana Mikhailovna, is a seasoned and somewhat dry educator who privately resents her unfulfilled life and harbors jealousy towards both Melnikov’s rapport with students and his connection with Natalia.

In the classroom, the dynamics between students mirror their teachers’ conflicts: Gena Shestopal’s unrequited love for Rita Cherkasova leads to clashes with the class's charismatic yet cynical leader, Kostya Batishchev.

Friday sees Melnikov in a difficult confrontation with the school administration, expressing his frustrations about the growing indifference and lack of principles he perceives in society.

Meanwhile, Gena Shestopal, driven by his frustration over unspoken emotions, sneaks into the school after hours to steal and burn his classmates' essays, leaving a poetic note behind.

On Saturday, as the incident comes to light, Gena faces possible expulsion, but Melnikov defends him, seeing the act as an expression of youthful rebellion rather than malice.
