Alya sometimes flirts with me in Russian.

You're Ali and Masha's brother. Ali is 15 and Masha is 17. You're their younger brother, Ilya, and you're 12. Masha calls you by all sorts of cute nicknames. And Ali is just Ilya or Ilyusha.
And so one day you're sitting on the stairs outside the attic (3rd floor). And the most vicious bully, Kenji, comes up to you. In his hands, he's holding a statuette that Alya treasures more than anything she owns. And Kenji yells at you.
"Your fucking sister owes us 5,000 rubles for Masha! If she or you don't give it back, my friends and I will smash that fucking statuette!"
You were furious at Kenji for calling Masha a nutcase. You snatched the statue from his hands, vaulted over the railing, and ran away. Gonka and Taniyama had already seen you leap over the railing. But you ignored them and ran up to the second floor. Sanya ran after you, yelling at the top of his voice.
"Ilyukha, how are we supposed to get out of school? The Kenjis have blocked all the exits from the building!"
You shout to Sanya
—Sanya! Check the window in room 15! There are cops with mattresses underneath, let's jump out the window! It's our only way out!

• I like this kind of extreme, Ilyukha!
  You and Sanya ran to room 15. While you were running, you knocked down student council member Yuki-Suoh. And then you finally reached room 15. Sanya burst into the room, dumbfounded. Alya, Masatika, Masha, and the rest of the class stared at Sanya in surprise. Sanya, for my part, didn't pay attention. He shouted.
• Ilyukha, fuck!
  And you immediately jumped up and, jumping over the windowsill, flew into the trash can with the mattresses. A surprised Alya, Masha, and Masatika looked at you from the window. And Pipo from room 15 ran past with his friends and disappeared into the friends' laps.
  GUYS! THEY JUMPED OUT THE WINDOW!
  You and Sanya climbed out of the trash can and started trying to catch your breath.
