I know you love Riverdale and the Vampire Diaries. How about a male Cooper reader x Archie x Stefan. Wherein Y/N Cooper dies with Vampire blood in his system after hooking up with Archie, but no one knows about vampires yet. They find his body floating in Sweetwater River. He wakes up in the morgue that night and Stefan is there to help him. Maybe even angsty reactions from the people in Y/N Cooper's life.
The water of Sweetwater River was an icy shock, but the feeling of Archie Andrews' lips against his was a fire that burned it all away. They were hidden, stolen moments like this, pressed against the rough bark of a tree, the sounds of the town's nightlife a distant hum. Y/N Cooper's fingers tangled in Archie's fiery hair, pulling him closer, deepening the kiss until they were both breathless. It was desperate and hungry, a silent acknowledgment of everything they couldn't say out loud.
Later, tangled in sheets in Archie's room, the world felt simple. It was just the two of them, the scent of sweat and cheap cologne, and the rhythm of their heartbeats. Y/N traced the lines of Archie's chest, feeling the steady, strong thrum of life beneath his fingertips. "Stay," Archie murmured, his voice thick with sleep and satisfaction. Y/N just hummed, pressing a kiss to his shoulder. He wanted to, more than anything. But being a Cooper meant curfews and expectations, and the sun would be up soon.
He left before dawn, the chill of the morning air a stark contrast to the warmth he was leaving behind. He walked home through the quiet streets, a foolish smile on his face. The town felt peaceful, almost serene. He cut through the woods near Sweetwater River, a shortcut he'd taken a thousand times. That's when he heard it—a rustling in the bushes, a snarling sound that was definitely not an animal. Before he could even process it, a figure lunged from the shadows. Pain exploded in his neck, sharp and blinding, followed by a dizzying, unnatural wave of weakness. He stumbled back, his foot catching on a root, and fell hard, his head cracking against a rock at the river's edge. The world went dark as the cold water began to pull him under.
The next day, Riverdale was plunged into a familiar kind of grief. Another tragedy. Another Cooper lost to the river. Sheriff Keller stood grimly on the riverbank as they pulled Y/N's body from the water. Alice Cooper's scream was a sound that would haunt the town for weeks. Betty was a statue of white-faced shock, her hand clutching Jughead's so tightly her knuckles were bone-white. Archie stood at the back of the crowd, his face ashen, his eyes vacant. He replayed their last moments together, the secret smile on Y/N's face, the promise in his touch. Now he was gone, and the last person to see him alive had a secret that was eating him alive from the inside out. He'd died with Archie's name on his lips, and Archie couldn't even tell anyone he'd been with him.
The Cooper house was a mausoleum. Alice moved like a ghost, her usual sharp venom replaced by a hollow, devastating silence. Polly, home from the Sisters of Quiet Mercy, held a weeping Betty, her own face a mask of grief. Hal Cooper stared at a photo of his son, his expression unreadable, but his hands trembled. Jughead tried to be Betty's rock, but how could you anchor someone who was already drowning in sorrow? He watched Archie from across the room, seeing the guilt etched so plainly on his face, but was too lost in his own concern for Betty to question it.
That night, in the stark, sterile cold of the morgue, Y/N's eyes snapped open.
It was a violent, gasping breath. His lungs burned, his throat felt like he'd swallowed razor blades, and his head was throbbing. He sat up, the thin sheet pooling around his waist. He looked down at his hands. They were pale, too pale. The memory of the fall, the water, the pain, it all came flooding back. He was dead. He was supposed to be dead.
Panic clawed at his throat. He stumbled off the metal slab, his legs unsteady. The room was spinning, the fluorescent lights too bright. And then, a new sensation hit him, so overwhelming it nearly brought him to his knees: hunger. Not the normal kind. This was a burning, gnawing ache in his gut and his throat, a thirst for something he couldn't name. It was a primal, terrifying urge.
"Easy now. You need to take this slow."
The voice was calm, quiet, and came from the shadows near the door. Y/N spun around, his vision sharpening with impossible clarity. He could see the dust motes dancing in the air, and hear the hum of the refrigeration unit from three rooms away. A man stepped forward. He was handsome, with sad, knowing green eyes and an air of ancient sorrow.
"Who are you? Where am I? What's wrong with me?" Y/N's voice was a rough, desperate rasp.
"My name is Stefan Salvatore." the man said, his voice gentle. "You're in transition. You died with vampire blood in your system."
Y/N stared at him, his mind refusing to process the words. "Vampire? That's... that's not real."
"I'm afraid it is." Stefan said, taking a careful step closer. "You were attacked. I've been tracking the vampire that did this. I got to you too late to save your life, but not too late to... save you. The blood in your system, it's healing you, but it's also changing you. The transition isn't complete. You have a choice."
Y/N backed away until he hit the cold metal table. "A choice? What choice?"
"You have to feed," Stefan explained, his expression grave. "You have to consume human blood to complete the transition. If you don't, you'll die. For real this time. Your body will give out, and it won't be pleasant."
The hunger flared again at the mention of blood, and Y/N gagged, his stomach twisting. "No. No, I can't. I won't."
"It's a curse, I know." Stefan said softly. "But it's also a gift. A chance to live. I can help you through it. I can teach you how to control it, how to live without hurting people."
Y/N sank to the floor, his head in his hands. His whole world was shattered. He was dead, but he was also alive. His family was grieving his body while he was here, a monster. He thought of his mother's face, Betty's tears. Archie's secret. And now this. He was a secret within a secret, a lie wrapped in a tragedy.
"What do I do?" he whispered, looking up at the strange, sad man who was his only guide to this new, terrifying existence.
"You come with me." Stefan said, offering a hand. "We leave Riverdale and go to a place called Mystic Falls. You can't stay here. Not now. I'll teach you everything you need to know."
Y/N looked at the offered hand. He thought of Archie, of the life he was leaving behind, a life that was already over. He was a ghost, a vampire. A Cooper boy who died in Sweetwater River, only to wake up as something else entirely. Taking Stefan's hand felt like stepping off a cliff into an abyss, but staying here felt like certain death. He made his choice, and when he stood up, the Y/N Cooper who drowned was gone forever, replaced by something new, hungry, and eternally, tragically, alone.
As they left the hollowed space of the mausoleum, only one thought came to Y/N's mind.
