On Monday morning, Nina arrived at school earlier than usual. She liked the empty corridors, the smell of chalk and the silence before the morning bell. She opened her locker and took out her history notebook, badly bent after the weekend. A sheet of paper fell out from inside, with a strange timetable on it. Under the title, someone had written in pen: History of Tomorrow - Room 313 - 7:10 a.m. Nina furrowed her eyebrows as school didn't start until eight. Olek appeared at the door, still with wet hair after the pool. She showed him the card, and he immediately asked in a hushed whisper. "Is this some kind of joke? We don't have room three hundred and thirteen at our place, seriously." "Maybe it's the new attic studio they're still renovating up there." "The attic is closed, but let's see on the evacuation plan by the stairs." There was a floor map hanging on the wall, and the number 313 didn't exist. There was a crackling sound from the speakers of the school radio, as if someone had just tested the microphone. A robotic voice said, Attention, lesson starts in five minutes. Olek snorted with laughter, but Nina could not smile at all. The hour in the note seemed more and more stubborn and true. Before the first bell rang, she suggested a trip to the third floor today. Olek shrugged his shoulders and then nodded, as if afraid to stay lower. The stairs smelled of plaster, and the new handrails cooled his hands through his sweatshirts. The higher they went, the fainter the lights became and the longer the shadows grew. At the end of the corridor they saw a freshly screwed sign: Room 313 strangely enough. It had certainly not been here before, which they both remembered accurately. Behind the door they could hear a gentle scraping, as if someone was sharpening chalk. Nina looked at her phone, which vibrated with a new notification suddenly. A calendar entry flashed on the screen: The Story of Tomorrow begins NOW. Olek whispered to go back in, but Nina touched the cold door handle cautiously. A whisper also came from inside, as if someone was calling her name. At the same moment, the doorknob moved from inside, quietly and decisively. On the other side, someone very calmly turned the lock without hurrying.
