Madison woke with a hangover that clamped down on her skull like a rusted vise. Pale, merciless morning light leaked through the half-drawn curtains and stabbed straight through her eyelids. She lay there a long moment, body leaden, mouth thick and sour, every cell screaming at the thought of movement. A raw, scorching thirst gripped her throat, sharper than the nausea twisting her gut. Finally she pushed herself upright with a low, guttural groan, the sweat-soaked sheets peeling away from her bare skin. Her legs shook as her feet hit the floor. She staggered across the room, steadying herself against the wall, one careful step after another, like a patient relearning how to walk.
In the cramped bathroom she clutched the sink and cranked the faucet wide open. Cold water burst out, bright and fierce. She bent low, drinking straight from the stream, swallowing greedily, letting it spill down her chin, over her throat, splashing across the tiles. When she straightened, her reflection slammed into her.
She froze.
The memories hit all at once—violent, jagged, like a reel spinning backward too fast. The bar. The fake laughter with the girls from her program. The drinks stacking up, the beers blurring into one another. And then ... Alan.
Everything that had been sitting heavy in her stomach since she opened her eyes detonated. Nausea surged, sharper, more real. She braced both hands on the sink, knuckles bone-white, legs turning to water. No. Not that. The fragments sharpened with every heartbeat: her body pressed against his, his hands roaming, the heat, the words tumbling out unchecked, the couch ... her mouth on him. Every single detail rushed back, cruelly clear, damning.
She nearly collapsed. Her knees buckled; she caught herself on the edge of the sink, breath locked in her throat. A scream clawed its way up, trapped between the hangover pounding her temples and the memories ripping through her skull. Anything but this. Not him. Not her brother.
In the worst possible second—while one last fragile bubble still floated, the one where this could still be nothing more than a drunken nightmare, a grotesque hallucination—a soft cough drifted in from the living room.
As if to announce himself.
Alan was still there. In her goddamn living room. And he knew she was awake.
Madison’s heart slammed against her ribs. She bolted back into the bedroom on unsteady legs, shutting the door behind her without a sound. Half-naked, she snatched the first thing she saw—a loose, crumpled T-shirt draped over a chair—and yanked it over her head, the fabric sliding cold against her still-damp skin. She was still wearing yesterday’s jeans; she hadn’t even bothered to take them off. She shot a panicked glance at the alarm clock. Still early. Class in a few hours. None of it mattered. The only thing that mattered was getting past that door.
She dropped onto the edge of the bed, fingers digging into her thighs, breath shallow and fast. She didn’t make a sound. Inside her head everything spun at breakneck speed—calculations, panic, desperate plans. She had no idea what to do. Part of her still prayed he would just stand up, leave, that every faint creak of the couch she heard would be the last, that he would walk out without a word. But he didn’t. He stayed right there, inches away on the other side of the wall, and he wasn’t moving.
She waited. Five minutes that felt like forever. Each second stretched the silence tighter, heavier, more unbearable.
Madison finally gave in. She pushed herself up, legs unsteady, the floor tilting beneath her bare feet. Every step felt like a battle, as if her body still refused to accept the reality waiting for her on the other side of that door. She laid her hand on the knob, hesitated for the space of a heartbeat, then turned it and stepped into the tiny living room.
Alan was there.
He sat on the couch, elbows planted on his knees, head buried in his hands. He didn’t move. He didn’t look at her. Not a single word. Just his hunched silhouette, motionless, as if the weight of the night before had nailed him in place. The silence was so thick it felt almost solid, a heavy substance that clung to the skin. Madison stood frozen in the doorway, heart hammering so hard she could hear it thudding in her temples. The knot that had been twisting in her stomach since she woke tightened another notch. She broke the silence first, her voice hoarse, edged with the irritation of a discomfort that made her want to scream.
“Tell me it’s not true ... it wasn’t a dream?”
Alan lifted his head slowly. Their eyes met at last. His were sad, a little ashamed, lids heavy. He didn’t need to speak. He didn’t need to nod. She understood. Instantly. As if the air between them had hardened around that brutal truth. Even if she still couldn’t fully grasp the sheer size of what it meant.
Leaning against the wall, unable to take another step, Madison felt her legs start to shake. Her voice came out weaker than she wanted.
“Alan ... what the hell are you ... doing here...”
He answered right away, awkward, the words tumbling out like he was scrambling for an excuse.
“You were completely wasted ... I didn’t want to risk you puking all over yourself while you slept or something...”
Then nothing. The silence dropped back down, heavy, suffocating. He added, almost to himself:
“I just crashed on your couch ... I must’ve passed out, I...”
He stood up then, clumsy, avoiding her eyes. He looked at her one last time, straight in the face, just for a second, before dropping his gaze.
“I should go...”
Madison cut him off, her voice cracking, almost pleading.
“It really happened...?”
Alan stopped dead, stunned. He stood there frozen, mouth half-open, searching for words.
“Uh ... I mean...”
He was already turning toward the door when, out of nowhere, she blurted:
“You ... you want a coffee?”
She surprised herself with the offer. The words had left her lips before her brain could stop them. Alan gave her a strange look, trying to read whether she was serious or if this was just a polite way of telling him to fuck off. Another thick silence settled between them, heavy, almost tangible. Finally he answered, a little more direct this time, his voice rough.
“Okay.”
Madison moved toward the kitchenette with mechanical steps, still numb from the hangover and the invisible weight pressing down on every movement. She started the coffee maker, the sound of water filling the reservoir echoing too loudly in the apartment’s oppressive silence. Behind her, Alan had taken a seat at the small round table, elbows planted on the worn wood, hands clasped in front of his mouth. He said nothing. He barely moved.
Inside, he was drowning.
Why the fuck did I stay? The question looped endlessly in his head, acidic, twisting in his guts. He hated himself for giving in to that protective impulse the night before—seeing her so drunk, so vulnerable, he hadn’t had the heart to leave her alone. But now? Now he was here, in her living room, with the memory of what had happened between them clinging to his skin like a second layer of shame. Did she remember everything? The way she’d pressed herself against him, her hands searching, her mouth...? Or only blurry fragments? He didn’t even dare imagine what she must think of him right now.
He stared at the table without seeing it, heart thudding dully. Neither of them dared speak. The silence was so thick it felt almost tangible, a heavy presence that filled every inch of space between them.
While the coffee brewed, Madison grabbed her phone from the counter. She scrolled through her notifications mechanically, more to keep her trembling hands busy than out of any real interest. The messages blurred past. She felt painfully awkward, back rigid, painfully aware that every second of this silence brought them closer to the moment they’d actually have to face what had happened.
The coffee finished dripping. She poured two steaming mugs, fingers clenched tight around the handles, and carried them back to the table. Without a word, she set one down in front of Alan. Then, as if she could no longer stand the emptiness, she held her phone out to him, screen lit on a specific message.
“What the hell did you have to tell me that was so important?”
It was the text he had sent her the night before—the urgent message saying he needed to talk to her about Rebecah, about everything that had happened in the last few days.
