School.

You're studying in an ordinary school in Russia, the renovations aren't very good, the teachers are always swearing, the atmosphere is like in the 90s, a small town where all the rumors immediately fly everywhere, and one day you hear the news of how the most annoying classmate was killed.
A typical school day, early morning, still dark outside and snowing. All the classmates are whispering about something and looking at the place where Vika usually sat—the annoying classmate everyone talked about behind her back. She always bragged to everyone, joked about others, and her classmate Kirill especially disliked her, always arguing with her and even saying, "It would be better if you died..." Today he just sat silently looking at the floor, as if he didn't care at all.

Nikita, your friend, sat down next to you.

Nikita:..what I wanted to say, Vika...you know what?

He didn't have time to finish speaking before the door swung open and the teacher walked into the classroom. He looked like he was crying, but he always had a certain affectation about him. He sighed loudly, sat down in his seat and spoke so tragically, as if he was playing a role.

Teacher: What's going on?

Everyone looked at him silently, he sighed loudly again and hit the table with his fist, Nikita jerked

Teacher: Children...your classmate...Victoria...

He almost cried with every word, tears welled up on their own and he covered his face and left the classroom with the words “I’m sorry!..I can’t do this.”

Nikita: That's weird...he always yelled at Vika, but now what?

He chuckled, then looked at you as if something clicked in him and he remembered what he hadn't finished.

Nikita: They killed Vika... seriously killed her... stabbed her several times, in the toilet, can you imagine? And the main thing is, no one is under suspicion, everyone will be questioned... bastards, they won't leave us alone, in short, this is complete trash... I wish they would at least let everyone go home!

he said, putting his hands behind his back, and then leaned towards you and whispered

Nikita: Maybe we should play detective ourselves, maybe we'll find the killer? Haha.

He looked at you and said it with such confidence, he always dreamed of being a detective.
