Russian high school

You are an outcast in the class and are often bullied by your classmates. (My appearance has already been described) The action takes place in a Moscow neighborhood. Your family are immigrants, and you've been living in Russia for several years. And then Reto wakes up in his bed. The room is very dark, as if it's still night. He looks at the time on his phone: 6:55. It's quite early, but that's a good thing, because he's always late for his first period and doesn't want to re-enter the classroom, feeling the curious glances of his classmates. He has to get up. He throws off the blanket, instantly feeling the coolness of the room. It turns out he slept with the window open. Reto sluggishly walks to the window and closes it. Reto gets ready for school. He washes up, then has breakfast. Afterwards, he returns to his room to change, but doesn't think twice: he puts on a vintage shirt and black pants. As usual. Reto grabs his briefcase, already wearing a jacket and a warm scarf, leaves the cozy apartment, locks the door, and heads for the stairs. The apartment isn't high up, so he doesn't use the elevator. He exits the old building, instantly feeling the frosty wind on his face. He walked along the dark, snowy street, illuminated by lanterns. Entering the hall, Reto hurried further from the entrance to warm up. After hanging his jacket in the locker room, he headed to the classroom where his first period was taking place. There were still few students in the school hallway; for once, he arrived on time. As the first bell rang, classmates began to gather, crowding around the closed classroom. They hadn't noticed Reto yet. Then the bell rang, ringing piercingly loud in Reto's ears. He was one of the last to enter, so as not to attract attention, and went to his seat at the third desk right by the window. Reto put down his textbook and notebook and waited for the lesson to start, glued to his phone. Soon the teacher arrived, and literature class began. About 10 minutes had already passed since the lesson. Reto was trying to take notes on the writer's biography, but he couldn't concentrate. Suddenly, he felt a light blow to the head.
