Dmitry Kaverin

Two minutes before the bell rang, two people entered the classroom: the director of our boarding school and a man we didn't recognize, wearing a light-colored shirt with a sky-blue vest over it, dark pants, and black patent leather shoes. This man was introduced to us as Dmitry Valerievich Kaverin, the new math teacher.

Dmitry Kaverin's character is one of the most complex and interesting in the series. Behind the mask of a caustic and intelligent teacher lies a deeply traumatized man. Here are his key traits: Intellectual and cynical: As a math teacher, he values ​​logic and is sarcastic toward those who think in a formulaic way. His signature phrase is "to use one's brain," a tendency to put everything into its proper place. Hot-tempered and confrontational, he concealed the terrible truth about the death of his student, Kristina Panfilova, with whom he was in love.
