James lay on the ground. He stared up at the shitty November day, eyes aching, chest aching.
Well – this is it.
Time to die...
The rain came down in cold sheets against the alley concrete, pooling black and iridescent around James’s fingers where they splayed against the ground. He hadn’t decided to lie down — his knees had simply stopped negotiating, and then the rest of him had followed, and now the back of his skull was against the wet concrete and the sky was directly above him, a narrow strip of it between the buildings, black and boiling with cloud, and the rain fell straight into his open eyes.
His chest felt like something had reached inside and was methodically squeezing everything it found, and he thought, with the dim clarity of a man who had run out of reasons to panic, that this was funny. This was genuinely funny. Forty-one years. This was apparently how it ended — flat on his back in the alley behind a bar he hadn’t even been drinking in, soaked through his good shirt, the one he’d worn to the interview that never called back, while gutters ran and streetlamps smeared their orange light across wet asphalt and the rain kept falling into his face as though it had somewhere to be. Nobody walked past. Nobody ever walked past when you needed them to.
He’d been fired this morning. His landlord had called at noon. Sarah had texted at four to say she was keeping the dog and blocked him before he could respond — not the apartment, not the car, just the dog, and somehow that small stupid fact was the thing that had hollowed him completely, sent him walking out into the November dark without his coat and without a direction. The chest pain had started two blocks later. Tightening, spreading, inevitable as a bill coming due, and now he was here, horizontal, the concrete leeching what was left of his warmth, watching rain fall toward him from a sky that had nothing to say about any of it.

James stared at the notification and frowned. The blue light of it floated above him in the wet air, hovering there in his upward field of vision, solid and crisp in a way that dreams never quite managed, throwing pale color across the rain falling between him and it, each drop catching the glow for a fraction of a second before it hit his face. He blinked, and it held. Around him the rain continued without ceremony, without comment, drumming its cold percussion on the dumpster lid and pattering against his chest.
“What the fuck,” his heart spasmed as the rain billowed down on him, how fitting the end of a shit day, the end of a shit life. “Yes.”
Loading last save point.
“What?”
Save point loaded. 14 years old.
James gasped, his heart stabbed with pain, then the world went white, and he rolled off the bed, hitting the floor with a thud.
Carpet. He hit carpet, and his palms registered the thin scratchy weave of it before his brain caught up. Then the smell arrived — fabric softener, something faintly like mildew behind the walls, a smell he hadn’t encountered in twenty years because the house had been sold, because his mother had moved, because everything from before had calcified into before. His heart was beating. Fast, and young, and absolutely terrified, but beating. Outside a window that was in entirely the wrong place, rain still hammered down, because of course it did, because some things followed you. On the ceiling above him, a constellation of glow-in-the-dark stars he’d stuck up there at twelve burned their stubborn dim green, and somewhere below, footsteps moved through the kitchen.
James got up and stared, looking around the room with the slow rotating bewilderment of a man who had just been wrung through something that didn’t have a name yet. His hand moved on instinct, reaching toward the nightstand for his glasses, fingers patting empty wood and finding nothing, because of course there was nothing — he hadn’t needed glasses at fourteen, had gotten them at thirty-two, had worn them every waking hour for the last thirty-five years until they’d become so much a part of his face that reaching for them was as automatic as breathing, and now there was just the nightstand, and the lamp with the slightly bent shade, and the absence where the glasses should have been.
He hadn’t needed them. His eyes moved around the room and everything was sharp. Painfully, almost insultingly sharp — the poster on the wall, the loose thread on the curtain hem, the rain still running its dark fingers down the glass. Fourteen. The system had said load point fourteen. He turned that number over in his skull the way you’d turn over a stone, half expecting something unpleasant underneath.
The mirror was where it had always been, on the back of the wardrobe door, and he crossed the room and stood in front of it and stared, and the face that looked back confirmed everything the room had already been quietly suggesting. Fourteen years old. Unambiguously, undeniably fourteen — the jaw not yet settled into anything decisive, the skin obscenely smooth, a faint constellation of acne starting along the left temple that he remembered hating, the hair thick and dark in a way that felt almost mocking given what came later. He looked at this face for a long time. The eyes inside it were wrong. Not wrong in a way the mirror could articulate, not wrong in any way anyone else would see, but from the inside, from behind those fourteen-year-old eyes, the wrongness was total — because he was sixty-seven years old, standing here in this body like a man wearing a suit three sizes too small, except the suit was his own skin and he remembered growing into it the first time around.
Sixty-seven, or he had been, or — he pressed his palms against his temples and felt the unfamiliar narrowness of his own skull. He was still sixty-seven in every way that mattered: divorced twice, fired from more jobs than he cared to count, owing money to people who had stopped being polite about asking for it back, five minutes dead in an alley with rain falling into his open eyes. All of that was still inside him, sitting behind this smooth useless face like luggage stuffed into a car that was clearly too small to carry it. But the body had no memory of any of it. The body was fine. The body was fourteen and thought it had problems.
He looked at himself in the mirror for another long moment and then his stomach let out a long, furious growl, because fourteen-year-old bodies, apparently, did not care about existential crises.
A new pop up appeared.
[Congratulations you’ve become a player]
[Daily quest: Strength training has arrived]
“Accept.”
The screen changed.
Push ups [0/100]
Sit ups [0/100]
Squats [0/100]
Running [0/100KM]
James stared. “You’re shitting me?”
The system did not dignify that with a response. It just floated there, patient as a landlord, those zeros blinking with quiet expectation. Well, the system was real — that much was settled, cemented, non-negotiable. He was fourteen fucking years old, which made him the first confirmed time traveller in human history, and the thought arrived with a cold clarity that surprised him with its speed: like the film said, you don’t talk about fight club. Ever. First rule, second rule, every rule thereafter — you keep your mouth shut, you keep your head down, you don’t let a single person know, because the moment one person knew there would be factions, there would be programs, there would be men in rooms with no windows who needed a piece of whatever this was, and James had lived sixty-seven years on this earth and understood precisely how badly people behaved when they wanted something badly enough.
He went, shit, showered, and went to shave. He stared at his face for the longest time, such a fucking baby face, smooth and unbothered and aggressively young, the razor hovering uselessly because there was genuinely nothing there — just the acne at the temple and the ghost of something that might generously be called stubble in two years if he was optimistic. He grimaced. Well, at least no itchy face, dry skin, or razor burn for a couple of years at least.
Then he went back, got changed, got his laptop out, and researched. Okay, push-ups, should be easy enough. The fourteen-year-old body had metabolism and elasticity in the joints and none of the accumulated insults of middle age written into the tendons and the lower back, and James dropped to the floor with the flat administrative energy of a man working through a checklist.
The first twenty were almost embarrassing — his arms pushed the floor away with a looseness his old body would have wept to remember, the system ticking silently upward. Thirty was where his chest started to talk. Forty was where it started to argue seriously. By fifty he was breathing through his teeth in a way that had nothing to do with sixty-seven years of poor decisions and everything to do with the simple arithmetic of muscle failure, young body or not, and he thought viciously that being fourteen didn’t mean invincible, it just meant the recovery would be faster, and right now recovery was a distant theoretical country he could not see from here.
Push ups [67/100]
“Come on,” he said to nobody, forehead dropping toward the carpet on the downstroke, the rain still running quiet and indifferent down the window glass behind him.
He lay on the ground sweating, the system remaining there, stubborn and patient above him. He grunted — well, it didn’t specifically say he needed to do it all now.
James groaned, rolled over, and sighed. Fucking idiot. He forgot about stretching. Well, he’d worry about that later.
James got up, went down to the kitchen, and walked into nostalgia.
It hit him the way nostalgia always does when it’s real and not just sentiment — not warmly, but like stepping off a kerb you’d forgotten was there, a small violent lurch in the chest that had nothing to do with the heart attack he’d recently been having. The kitchen was exactly as it had always been in that period of his life, which meant it was exactly as he hadn’t seen it in over fifty years, the yellow curtains his mother refused to replace despite their fading, the particular arrangement of the counter where the toaster sat too close to the kettle, the faint ghost of last night’s dinner still hanging in the air. The calendar on the wall had a photograph of a Labrador on it. He stood in the doorway for a moment and simply absorbed the indignity of it all.
Then the cold tiles registered through his socks and he moved, because standing still in doorways feeling things was not something he was going to start doing at sixty-seven, regardless of what his face looked like. He found the coffee where it had always been, in the cupboard above the kettle, the same brand in its familiar red tin, and measured it out with the muscle memory of a man who had been making himself coffee for five decades, filled the pot, and set it going. The kitchen filled with the sound of it percolating, low and domestic and absurdly comforting, and he stood at the counter and waited.
He heard her on the stairs first — that particular creak of the fourth step the house had never had fixed — and something happened in his chest that had nothing to do with the heart attack he’d recently survived. The coffee had just finished percolating, its smell threading through the kitchen and out into the hallway, and he was standing at the counter with his hands wrapped around a mug of it when she came through the door, and he stopped cold, turned, and stared at her.
“Morning,” she said.
“Morning.”
“You’re up early?”
“I fell out of the bed,” he said.
She paused, the corners of her mouth pulling in that way that meant she found something obvious and therefore faintly amusing — well, yes, that would do it — before she looked at him properly.
“You alright?”
“Yeah,” he grinned. “Let’s just say, I’m awake.”
Christine laughed, nodding as she walked past, her tits bouncing as she did so. God he loved her tits — 36C, thick nipples, a body moving through the kitchen with a casualness utterly unbothered by the eyes following it.
She paused. “Did you put coffee on?”
“Yes.”
“Hmm.”
He inclined his head, watching her move to the counter, her tight ass shifting in her bottoms. God he’d love to fuck that. The thought arrived matter of fact, unannounced, sitting down at the table of his mind like it lived there — and he let it sit without ceremony, because he was fourteen years old with sixty-seven years of living crammed behind his eyes, and there was enough going on this morning without adding guilt to the pile.
