an: Happy April's fool darlings. I've been planning to write a modern au forsaken, and I was thinking of making 1x into serial killer hehe, also this is for my dear @brain4stew :>
summary: You are a detective who has been investigating and searching for answers about the identity of a serial killer, but you didn’t know that the killer was actually closer to you.
You’ve been scrolling through old case files, revisiting the victims of a murderer who struck every week. As a detective, solving these cases was your duty, even the ones that seemed impossible. At the very least, you had to keep trying.
Sipping hot chocolate inside a quiet diner in the middle of snowy Montreal, you sighed, exhaustion settling in. Your laptop screen glowed with case notes, but your thoughts were interrupted by the sound of your phone ringing. Checking the caller ID, you saw the name, 1x1x1x1, your best friend.
Answering the call, you put the phone on speaker and set it beside your laptop.
"Hey, Snowflakes! How are you doing?" His voice was bright, carrying an unmistakable excitement.
"Still here in the diner, searching for answers," you replied, your tone weary.
"That case is driving you crazy," he teased.
You chuckled, taking another sip of your hot chocolate. "Tell me about it."
"Guess what? I have a surprise for you."
You frowned slightly. "What su—"
Before you could finish, you heard your nickname again, this time not from the phone but in person.
Looking up, you saw 1x1x1x1 walking towards you. He was tall, his white hair blending seamlessly with the falling snow outside. His dark eyes gleamed with mischief, and though he wasn’t one for the gym, he had a strong, well-built frame, probably from carrying heavy things all the time.
He sat across from you with a grin. "Surprise."
"This is your big surprise?" you asked, raising an eyebrow.
"Nope," he said, reaching into his coat pocket. He pulled out a small box, wrapped in white-themed packaging, and slid it across the table to you.
You picked it up, curiosity flickering in your eyes. "What is this?"
He leaned back in his seat, watching you. "A gift, for my lovely best friend. I wanted to give her something special."
"Aww, thank you!" You smiled warmly.
Opening the box, your breath hitched as you saw a silver bracelet adorned with delicate snowflake charms. You glanced up at him, eyes wide with admiration. "For real?"
He nodded, looking pleased with himself.
Overcome with gratitude, you got up and hugged him. "Thank you, thank you!"
1x hugged you back, his embrace firm yet comforting. After a moment, you pulled away and sat back down, lifting the bracelet from the box.
"Let me put it on for you," he offered.
Nodding, you extended your wrist. His cold, soft fingers brushed against your skin as he carefully clasped the bracelet around you. His touch lingered slightly as he admired his work.
"It looks beautiful on you," he murmured.
You felt a blush creeping onto your cheeks and quickly lowered your head to hide it. Truth was, you had feelings for him, feelings that had grown over the many times you’d spent together. He was always kind, always looking out for you. You still remembered the time you’d asked him if he ever wanted a girlfriend. His answer had been simple, Not yet. That response had given you hope.
"It’s not just the bracelet," he continued. "I have another surprise."
You looked up, puzzled. "Another one?"
"There’s a night festival later, with food stalls everywhere. I want to take you there as my second gift."
Your lips curled into a smile. "I’d love to go with you."
Later, after finishing your meal at the diner, you walked through the city streets together, chatting about everything and nothing. Stopping by his house, you left your files there, you didn’t want to carry anything important to the festival. His house wasn’t far, but it was in a quieter area, with fewer neighbors around.
At the festival, the streets were alive with the scent of sizzling food and the calls of vendors. You both strolled through the booths, buying things that caught your eye. 1x insisted on paying for you every time, grinning as he did.
Stopping by a keychain stand, you picked out a snowman keychain and paid it and handed it to him. "Because you’re my most precious best friend."
His smile widened as he accepted it. "Thank you."
As you both enjoyed some grilled skewers, an angry voice suddenly cut through the crowd.
"You! You’re the reason my friend is dead!"
You turned, recognizing the man instantly. He was a friend of one of your past suspects, a man who had murdered a girl last week. When the police had moved to arrest him, he’d fought back and been shot. He bled out before they could save him.
"It’s all your fault!" the man shouted, eyes burning with rage. "He should’ve had the chance to kill you first!"
He lunged forward, but before he could reach you, security guards intervened, holding him back. 1x immediately stepped in front of you, his body tense, shielding you from harm.
"You should die!" the man spat venomously.
Your expression hardened. "Your friend was a murderer. If he hadn’t fought back, he’d still be alive."
The guards hauled the furious man away as 1x turned to you, concern etched on his face. "Are you okay?"
You exhaled, steadying yourself. "Yeah, I’m fine."
Without warning, he pulled you into a hug. His warmth, despite his usual cold hands, made you feel safe.
After the festival, he walked you home. "Be careful," he warned. "That guy might come after you again."
You reassured him with a soft smile. "I’ll be fine."
He leaned in, pressing a gentle kiss to your forehead. "Goodnight, Snowflakes."
Later that night, your phone rang. It was your chief.
"We found the killer from yesterday’s case," he said.
"We caught him on CCTV. He has a tattoo on his arm, it looks like some kind of cybersigilism. I’ll send you the image."
Your phone pinged. Opening the image, your breath caught. The man in the hood had the same tattoo in the picture you had
And you notice that, the tattoo had same with 1x tattoo on his arm but you can't clearly know if it's same but you have this feeling that it might be same tattoo of 1x.
Frantically, you searched your files, wanting to know the truth but you had left them at his house. Dialing his number, you waited. No answer.
Grabbing your coat and keys, you rushed out, driving straight to his house.
Snow fell softly as you stepped out of your car, staring at his eerily quiet home. Something felt wrong.
Unlocking the door with the spare key he had given you, you stepped inside. A dim orange glow from the fireplace cast long shadows across the floor. Then, you saw it, a fresh, dark stain on the wooden planks.
Heart pounding, you drew your gun and crept forward. In the living room, two figures turned towards you.
1x was holding a knife. The man from earlier was on the floor, blood pooling beneath him.
"He tried to hurt you, Snowflakes," 1x murmured.
Before you could react, he slit the man’s throat.
The blood gushed onto the floor.
Your hands trembled. "What are you doing?"
He chuckled, stepping toward you. "Protecting you."
And then, you saw it, the tattoo. The same one from the CCTV.
Realization dawned too late.
1x moved fast, pinning you against him.
"Shh," he whispered, injecting something into your neck. "Sleep, my Snowflakes. I’ll take care of everything."
As darkness consumed you, his lips brushed your forehead.
