a/n: hi! I was sitting around on my phone, and then I thought, what if I wrote a Backrooms-themed fic? And here we are. I hope you enjoy it! Btw, reader and Phainon are both students :>
Chapter 1
Outside the coffee shop's panoramic window, an autumn rain was falling. Large tears of rainwater streaked down the glass, breaking the neon signs of the evening city into hundreds of colorful reflections. Inside the shop, the air was filled with the scent of freshly ground coffee, cinnamon, and old paper. It was your favorite place, always quiet, with the soft, dim lighting of the floor lamps creating a cozy and isolated atmosphere.
You and Phainon had been sitting at a corner table for three hours. You had a stack of history lecture notes in front of you, but your studies were progressing slowly.
"You're frowning again," Phainon said in a soft, velvety voice.
You looked up from your notes and met his warm, inviting gaze. Phainon tilted his head slightly to the side, a subtle, gentle smile playing on his lips. He always exuded an extraordinary sense of calm. He had an uncanny ability to make any worries fade away, as if he were a safe harbor in the midst of a storm.
"I just don't understand this chapter," you sighed, rubbing your temples wearily. "The letters are already blurring."
Phainon chuckled softly, a pleasant, lulling sound. He carefully pulled your notebook closer, turning it towards him, and tapped the tip of his pencil against the intricate diagram.
"It's simpler than it seems. Let me explain it again from the beginning," his voice was so soothing that you couldn't help but relax your shoulders. For a moment, his fingers accidentally brushed against your palm as he handed you a pencil. The warmth of his touch sent a pleasant flutter through your chest.
You sat there for about half an hour, while Phainon patiently and gently explained the difficult terms. Finally, he closed his notebook.
"I think that's enough for today. You've done a great job. Let's pack up and stop by the grocery store on the first floor. My mom asked me to pick up some things for dinner, and you might as well grab something to eat before bed."
You happily agreed. You packed your textbooks into your backpacks, went down to the ground floor of the building where the large supermarket was located, and took a shopping cart. Phainon walked slowly between the rows. He chose the food with his usual care: carefully checking the expiration dates, carefully putting everything in the cart, turning around to you from time to time and gently asking if you wanted anything.
You reached the farthest, half-empty wing of the store, where household goods were sold. For some reason, it was suspiciously empty, and the usual music from the supermarket's speakers suddenly stopped.
"Hm, that's strange," you remarked as Phainon stopped near a long rack of laundry detergents. "It looks like they're renovating here. Look."
In front of you, right between two tall shelves, there was a strange opening instead of the usual concrete wall. There was no door, just a narrow corridor with old, faded yellow wallpaper on the walls. A monotonous, barely audible electric hum came from the depths of the passage.
"It's really strange. Let's not go there, just in case," Phainon smiled softly, and warm sparks flashed in his eyes. "Let's go to the ticket office instead, we still have to study for the exam."
He gently touched your elbow, about to turn the cart around. But for some reason you were slow. Your gaze seemed to be drawn to this strange yellow corridor. It seemed to you that in the depths of it, in the midst of absolute silence, there was a faint, barely noticeable gleam — as if someone had turned on the phone screen.
Curiosity was stronger than caution.
"Wait a second, I'll just take a look," you said quietly.
Before Phainon could stop you, you took a step forward, entering this strange passage.
"Hey, where are you going, Y/n? Wait," Phainon sighed. There was a soft, almost parental acceptance of your adventurous spirit in his voice. He left the cart and confidently followed you down the hallway, reaching out to grab your shoulder.
You took another step deeper... and in that moment, the floor beneath your foot simply disappeared.
You didn't stumble or fall; you literally sank through the solid tiles, as if they had become transparent like smoke. A scream caught in your throat. Phainon, who was standing right next to you, reacted instantly, lunging forward and wrapping his arms tightly around your waist in an attempt to hold you up. However, an unknown force also pulled him down. For a brief moment, the world blurred into yellow streaks, and all the sounds of the store ceased abruptly, leaving you with a wild sensation of falling into nothingness.
You both came to your senses at the same time, inhaling sharply in the stuffy, dry air.
You found yourself sitting on the floor, with Phainon holding you in his arms, his breath coming in short pants, shielding you from the unknown. His face was slightly pale as he pulled back to examine you, but his clear blue eyes remained calm and focused.
He gently touched your cheek, helping you to recover.
"Are you all right?" His pleasant, velvety voice was quiet, but it was filled with so much enveloping warmth and genuine concern that the approaching panic subsided a little. "Y/n, look at me. It's okay, I'm here. Did you hit yourself?"
"I... I don't think so," you whispered, swallowing hard. You looked around, and your heart sank.
The supermarket has disappeared. You were sitting on an old, damp carpet that exuded a faint smell of dampness. There was an endless expanse of empty rooms with strange, crooked walls covered with sickly yellow wallpaper. And there were rows of fluorescent lights right above your heads. They burned with an unnaturally bright light and hummed loudly, monotonously, clogging up all thoughts.
You turned back frantically. But there was only a solid, blank yellow wall behind you. There was no way out.
