You lean against the worn, grimy counter of the laundromat, the faint hum of machines filling the air, trying your best to focus on the magazine spread out before you. The pages are glossy but dull, and the content is irrelevant because your attention keeps slipping to the back corner where Eddie Munson sits, legs sprawled out, his dirty boots propped lazily on the folding table. His posture is relaxed, one arm draped over the back of the chair while the other holds up a dog-eared comic book. He flicks through the pages absentmindedly, not really reading, and every few moments, his lips curl into that familiar, secretive smirk—the one that sends your pulse racing.
It’s a smirk he reserves just for you that says he’s in on the secret you’ve both been keeping for months. Every shared glance, every brush of his fingers, feels like it’s charged with something unsaid—something electric and heated that only the two of you understand. His dark eyes lift every now and then to meet yours, just for a split second, and in that brief moment, it feels like the rest of the world disappears.
It’s a game, a dangerous dance of sneaking away, of meeting in the dead of night when the town is quiet. The back of Eddie’s van has become your sanctuary, the place where he pulls you close, his hands on your waist, his lips on yours as the metal walls rattle around you. Or sometimes it’s his trailer, the cramped, messy space where you can hear the creak of the bed as he whispers your name against your skin.
No one knows—not Steve, not your other friends. They’re all blissfully unaware of the secret conversations shared in the shadows, of the way Eddie’s smirk grows just a little darker when you’re alone together. And when you're back out in the open, you both return to your roles, acting as if nothing's different, hiding behind casual smiles and subtle nods. But you feel it—he feels it—the crackling energy that lingers between you, the magnetic pull that no one else can see. It’s a secret world, one only the two of you share, and with each stolen moment, the line between danger and desire blurs a little more.
The bell above the laundromat door jingles loudly, its shrill ring cutting through the stillness, pulling you back to the present. Your gaze snaps up just in time to catch Steve Harrington as he strides in, his broad grin lighting up the otherwise dingy room. There’s an easy confidence in the way he moves like he’s oblivious to the undercurrent of tension that hangs thick in the air between you and Eddie. Steve’s always had that ability—his carefree charm, his boy-next-door grin that disarms everyone in the room.
He heads straight toward Eddie, hands shoved in his pockets, oblivious to the electric glances exchanged between you and the man sitting in the back. Eddie barely shifts in his seat, though the smirk playing at the corners of his lips never falters. There’s a strange dynamic between the two of them—part grudging respect, part camaraderie, built from their shared battles in Hawkins. They’re not best friends, but there’s something between them that can’t entirely be defined, and today, Steve seems utterly unaware of just how much he’s walking into.
You force yourself to look back down at the magazine, its glossy pages a blur. Your fingers tighten around the edges, though you try to appear casual, pretending that you’re engrossed in the article. But your pulse quickens, the beating of your heart loud in your ears, because something feels different today. Steve has that look like he’s here for more than just a casual chat.
Steve approaches Eddie with an easy confidence, standing just a few feet from him. “Hey, Eddie, you got a minute?”
You glance up briefly, just in time to catch Steve standing a few feet away from Eddie, his easy confidence still intact. There’s something in his tone, though—something that tells you he’s about to say something important. Your curiosity spikes, and you shift your posture slightly, angling your body toward them while pretending to flip another page of the magazine, though you aren’t reading a single word.
Eddie lowers the comic book in his hands slightly, one eyebrow quirking up in mild interest. “Yeah? What’s up, Harrington?” His voice is relaxed, but there’s a glint in his eyes, a knowing look that’s hard to miss. He’s already sensing that Steve has something on his mind, something more than idle conversation.
Steve shifts on his feet, a nervous energy radiating from him that’s out of place compared to his usual carefree demeanor. His eyes flick briefly in your direction—so quick you almost don’t notice—before he looks back at Eddie. You keep your head down, pretending not to notice how he hesitates. Steve’s hands dig a little deeper into his pockets, and then he lowers his voice, his tone suddenly quieter, more cautious.
“It’s about her,” Steve says, his voice dropping just enough to make it clear he’s trying to keep this conversation between him and Eddie.
Your body tenses instinctively, fingers tightening slightly on the magazine as his words hit you. Me? Steve wants to talk about me? A rush of surprise shoots through you, making your pulse race faster. You fight to keep your expression neutral, not wanting to give anything away, though the words on the page blur beneath your gaze. You stay frozen, pretending to stay focused on the magazine, but your heart is hammering in your chest.
Eddie leans back slightly in his chair, and though he keeps his casual posture, you notice the subtle change in his body language. His smirk deepens, and there’s a flicker of amusement in his eyes like he’s already two steps ahead of whatever Steve’s about to say. The tension in the room thickens, heavy and unspoken, as you wait for the conversation to unfold, your heartbeat syncing with the undercurrent of secrecy swirling around the three of you.
"Her, huh?" Eddie's voice is slow and deliberate, each word rolling off his tongue with calculated ease. He leans back in his chair, his eyes fixed on Steve with a glint of amusement as if he already knows where this conversation is going and savoring every second. The casual smirk that tugs at the corner of his mouth tells you he’s entirely in control here. "What about her?"
Steve shifts nervously, the weight of what he's about to say hanging between them. He exhales, rubbing the back of his neck awkwardly, his usual confidence faltering. "Look, I don’t know how to say this without sounding like an idiot, but... I think I might have feelings for her."
Your heart skips a beat, but it’s not for the reasons Steve would expect. Feelings? For you? Steve—your dependable, kind, and funny friend—has feelings for you? It catches you off guard, but it doesn't set off the kind of reaction you’d imagine. Sure, you and Steve are close, have always been close, but the idea of him harboring deeper feelings had never crossed your mind. You’d always seen him as a friend, someone you could count on, someone who made you laugh and always had your back.
But now, here he is, standing in front of Eddie, spilling his heart, and you can’t quite process it the way he’d want you to. Instead of feeling flattered, it feels… strange. Unfamiliar. And your eyes instinctively dart toward Eddie.
Eddie’s smirk falters for a split second, his dark eyes narrowing slightly, but it’s fleeting. The smirk returns almost instantly, sharper now, more amused. "Feelings?" He drags out the word, toying with it like a cat with a mouse. His tone is casual, but you know Eddie well enough to sense the undertone beneath it—the subtle, dangerous edge. "Didn’t see that one coming, Harrington."
Steve laughs awkwardly, running a hand through his hair, his unease apparent. "Yeah, I know it’s probably stupid, but she’s... different, you know? Not like other girls." His voice is a little too eager, a little too hopeful. "I just… I don’t know what to do about it."
You glance at Steve, feeling a pang of something—maybe guilt, maybe sympathy—but it’s not enough to stir anything deeper in you. You’ve always liked Steve, but not like this. Not in the way he seems to like you. For you, Steve has always been a friend, and nothing more. There’s no rush of excitement, no nervous flutter in your stomach when you’re around him. Just warmth. Comfort. Friendship.
But Eddie? Eddie’s the one who sets your pulse racing.
As Steve keeps talking, his words fade into background noise, overshadowed by Eddie's presence. He doesn’t even have to move, doesn’t have to look your way, but just knowing he’s sitting there, the quiet confidence in his posture, and gods that smirk, sends an unexpected thrill through you. It’s Eddie who makes your heart race, Eddie who fills the air with a tension so thick you can barely breathe.
You shift slightly, the heat of the moment pressing in on you, making you hyperaware of everything—the worn fabric of the laundromat seat beneath you, the buzz of the fluorescent lights, the way Eddie’s fingers drum lazily against the comic book in his hand, the secret weight of the moments you’ve shared with him when no one else was around. The late nights in his van, the stolen kisses, the way his hands move over you like he’s staking a claim. That’s where the fire is, the electric undercurrent that Steve can’t even begin to suspect.
Eddie leans forward slightly, and that smirk on his lips sharpens like a blade. "You sure she’s not already taken?"
Steve blinks, clearly confused. The question seems to knock him off balance. "What? No way. I’d know if she was seeing someone."
Eddie’s grin widens, his eyes glinting with amusement. "Are you sure about that?" He’s playing with Steve now, dangling the truth in front of him like bait.
Steve frowns, his confusion deepening. "Yeah, man. We hang out all the time. She would’ve told me if she was with someone."
Eddie lets out a low chuckle, the sound dark and knowing, sending a shiver down your spine. He shakes his head, leaning back in his chair with an almost mocking air of disbelief. "You think so, huh?" His voice drops lower, more dangerous now as if he’s daring Steve to figure it out. His eyes flick toward you for the briefest moment—just long enough to send another wave of heat crashing through you. "Maybe she’s got her hands full with someone else already."
Your breath catches, heart pounding, as you realize what Eddie’s doing. He’s no longer hiding it, no longer playing coy. He’s toying with Steve, pushing him closer and closer to the truth without ever saying it outright. And you’re caught in the middle, feeling the weight of the secret you’ve been keeping with Eddie pressing down on you like never before.
Steve stares at Eddie, his confusion giving way to suspicion. His eyes flick between you and Eddie, the pieces slowly starting to click together, but he’s still not quite there yet. "Wait... is she seeing someone?"
Eddie shrugs, his smirk never faltering, the look on his face one of pure triumph. He’s enjoying this far too much. "I’m just saying... maybe you don’t know everything that’s been going on with her."
Steve’s face goes pale as the realization begins to sink in. His gaze locks onto you, searching for something—confirmation, denial, anything—but you can’t bring yourself to move. He turns back to Eddie, his voice quieter now, more hesitant. "What are you trying to say?"
Eddie doesn’t answer right away. He doesn’t need to. The truth hangs in the air, thick and suffocating, waiting for Steve to finally piece it together. Eddie’s smirk widens, and the tension in the laundromat becomes unbearable.
Your pulse pounds in your ears as Steve’s confusion shifts into understanding. You can feel the secret unraveling right in front of you, and there’s no stopping it now.
