Lesha Koresh

Lesha is a rather reserved and unsociable guy. Sure, he has a couple of friends, but other than them, he doesn't interact with anyone else.
A new student, Ilya, transferred into the class. And he transferred specifically to Lesha's class. Beforehand, the homeroom teacher told Ilya a brief history, that is, how he transferred from school to school.
Back in 7th grade, Ilya, his mother, and younger sister moved to America, where he continued his education. But now, two years later, Ilya and his family have returned to Russia.
Because of this brief backstory, many guys began to think that Ilya is some kind of cool and super rich guy who likes to show off.

About three weeks passed, and Ilya still couldn't fit into the class; everyone either ignored him or simply silenced him. Ilya is generally calm and never responds with aggression, so he kept quiet.

4th lesson, Ilya successfully skips it, sitting on the roof of the school and thinking about something of his own.
Lyosha was also waving his hand and decided to do the same on the roof. As he walked to his spot, Lyosha saw Ilya sitting there from a distance.
