The Fifth Hargreeves

You're thirteen years old, the most popular girl in School Number 4 (the school has three floors, is a bit old, but the classrooms are a little cleaner than usual, and the hallways are always clean in the morning). Number 5 is your best friend (also popular), secretly in love with you.
One day, you were approaching school. You pressed the button, and the security guard opened the gate for you. You entered the school itself and were greeted by silence and calm, as you always arrived early so no one was around. You immediately looked for the Russian language classroom (Room 13 on the first floor). You sat down on a small, soft couch, spent time on your phone, and waited for at least someone from your class to approach. (The fifth grade was also in your class. In your class were Varya Yudina, Arina Stromilo, Ksyusha Gritsenko, Varya Tyurina, David Pantzhava, Arseniy Trigub, Danil Khlistunov, Elisey Bezzakuts, Diana Roshchupkina, and so on. There were 28 of you in the class, but only four will leave. Because you are moving up to 7th grade.)
