Getting discharged from Oakhaven General turned out to be less like leaving a hospital and more like a state farewell.

Leo had expected to sign a form, maybe get a pamphlet about concussion warning signs, and slip out a side door. Instead, by the time he reached the lobby, there was a small crowd. The young nurse from the day before was there, dabbing at her eyes with a tissue. The doctor stood with her clipboard pressed to her chest. Two orderlies he'd never met lingered by the doors as though they'd been assigned to watch him leave and were taking the duty seriously.

"Now, you have our number," the doctor said, for the third time. "If anything feels wrong - dizziness, headache, anything at all - you call. Day or night. Day or night, do you understand?"

"I understand," Leo said. "Thank you. Really, you've all been so -"

"And you'll take a taxi," she went on, talking over him in the manner of someone who had decided this point was non-negotiable. "Not the bus. The bus is - there are crowds, it's not safe, anything could happen. A taxi. We've called one for you. It's waiting."

"I was just going to walk, it's not far -"

The collective intake of breath stopped him. The young nurse actually grabbed his sleeve, then let go immediately as if she'd burned herself.

"A taxi," the doctor repeated, gently, the way you'd repeat something to a person standing too near a cliff edge.

So Leo took the taxi.

The driver, a woman with grey hair and kind eyes, spent the entire fifteen-minute journey glancing at him in the rearview mirror with an expression of soft wonder, asked him four times if the temperature was comfortable, and flatly refused to accept payment.

"Put your money away," she said, scandalized, when he tried. "The very idea. You just get home safe."

Leo got home safe, somewhat poorer in confidence and richer in confusion, and stood for a while on the pavement looking up at the building the taxi had brought him to.

It was, apparently, where he lived.

This was the part that made his head hurt worse than the concussion. He had a key in his pocket - he'd found it among his things at the hospital - and when he climbed the stairs to the third floor and tried it in the door of flat 3B, it turned. The door opened onto a small, tidy apartment that he had never seen before in his life and that some deeper, stranger part of his brain insisted he had lived in for years.

There were photos on the wall. Him, in places he didn't remember being. A certificate with his name on it. A jacket on a hook by the door that fit him perfectly when he tried it on, that smelled faintly of a laundry detergent he somehow knew the name of without being able to say how.

It was like wearing someone else's memories one size too big. They almost fit. They didn't quite.

Leo sat down heavily on the sofa - his sofa, the not-quite-his sofa - and pressed the heels of his hands into his eyes.

"Okay," he said. "Okay. Think. Be normal about this. People wake up in alternate hospitals with borrowed lives all the time. It's fine. It's totally fine."

It was not, by any reasonable standard, fine. But Leo had spent sixteen years getting very good at making peace with things that weren't fine, at quietly absorbing the strange and the disappointing without making a fuss, and the habit held now when he needed it most. Panicking wouldn't tell him anything. Information might.

He found the remote and turned on the television.

The first channel was the news. A sharp-suited woman behind a desk was discussing economic policy with another sharp-suited woman, and Leo nearly moved on - and then the anchor said, "- and in lighter news, the Young Men's Wellness Initiative has announced expanded funding for protective programs in schools nationwide, ensuring our most precious citizens receive the care and security they deserve -"

Leo paused, thumb over the button.

The screen cut to footage of a school. A cluster of boys - maybe five of them, in a sea of girls - were being escorted across a courtyard by what looked like an honor guard of female students, who carried their bags, shielded them from the drizzle with umbrellas, and generally treated them like visiting dignitaries. A caption read: KEEPING OUR BOYS SAFE: A NATIONAL PRIORITY.

He changed the channel.

An advertisement. A handsome young man sat by a window, looking pensive, while a warm voice intoned, "He's one in seven. Shouldn't his health be one in a million? VitaMale - complete daily nutrition, formulated for the men who matter most." The man smiled directly at the camera. Somewhere off-screen, a studio audience sighed.

Leo changed the channel again.

A game show. The set was glittering, the host beaming. "Welcome back to Win His Heart, the show where twelve eligible women compete for one chance at courtship!" The camera panned across a row of women, fierce and glamorous and clearly out for blood, then to a single nervous-looking young man on a raised platform, being fanned and offered refreshments. "Tonight's challenges will test our contestants' devotion, their generosity, and their willingness to fight - figuratively, ladies, figuratively - for the prize of a lifetime!"

Leo turned the television off.

He sat in the sudden quiet, and the pieces, which had been drifting around the edges of his mind since he woke up, began - slowly, reluctantly - to settle into a shape.

There was a bookshelf against the far wall. He went to it the way you approach something you're afraid will confirm what you already suspect. Most of the books were ordinary - novels, a cookbook, some battered school texts. But one shelf held what looked like reference books, and one of them, a thick hardback with a serious cover, was titled simply: A Social History of the Shift.

Leo took it down and started to read.

He read standing up at first, then sank to the floor with his back against the bookshelf, turning pages, and the world he had woken into assembled itself paragraph by paragraph.

Three generations ago, the book explained, something had happened. The Shift, they called it - a cascading genetic change, its exact cause still debated, that had altered the ratio of male to female births across the entire population. Within two decades, the numbers had stabilized at a staggering and unprecedented figure: roughly one man born for every seven women.

And a society, faced with that, had reorganized itself around the scarcity.

Men became precious. Not metaphorically - structurally, economically, legally precious. They were a vanishing resource to be protected, cherished, kept safe. The old scripts of who pursued whom, who provided, who protected, who waited to be chosen, had inverted entirely and then calcified into a new normal so total that the people living inside it could no longer see it as anything but obvious.

Women built the world now. They ran the governments and the companies, drove the economy, competed - fiercely, the book noted dryly, sometimes ruinously - for the attention of the men they hoped to court. And men, for their part, were raised to be cherished. To be careful. To be cared for. A man who cooked for himself, who carried his own bags, who poured his own water, was regarded with the same baffled tenderness Leo's own world might have reserved for a duke who insisted on scrubbing his own floors. Charming, perhaps. Eccentric. Faintly heartbreaking. Certainly not necessary.

Leo set the book down in his lap and stared at the opposite wall for a long time.

The nurses. The doctor. The taxi driver who wouldn't take his money. The way the whole room had frozen when he caught a falling teapot, when he said be careful, when he tried to do the smallest, most automatic things for himself.

It hadn't been because he was a patient.

It had been because he was a man. And men, here, did not catch teapots for nurses. Men did not steady anyone's elbow or worry about anyone else falling. It ran entirely the wrong way down the grain of everything this world believed.

"Oh," Leo said quietly, to the empty flat. "Oh, that's - okay. That's a lot."

He should have felt, perhaps, a thrill at it. Some people might have. He had landed in a world where simply existing made him valued beyond measure, where he could want for nothing, where doors would open and crowds would part and people would compete for the privilege of carrying his bag.

What Leo felt instead was a low, creeping dread.

Because being valued like that wasn't the same as being seen. He understood that instinctively, the way he understood most uncomfortable things - quietly, without wanting to look directly at it. They didn't cherish him. They cherished what he was. The category. The scarcity. If he were a different man entirely, a worse one, a stranger, they'd cherish him exactly the same, because the thing they prized wasn't anything he'd done or chosen or earned. It was just the accident of what he'd been born.

He knew that feeling. He knew it from the other direction, from a whole life of being unremarkable, of being the one nobody noticed, the middle child in the group photo whose name you had to be reminded of. He had spent years being invisible. Now he had apparently traded it for the strangest kind of visibility there was - the kind where everyone stared and nobody actually looked.

And then, sitting on the floor of a flat that wasn't his, Leo did the thing that would shape the next several catastrophic months of his life. He talked himself out of understanding what he'd just understood.

"But that's for - special ones," he reasoned aloud, because it was less frightening than the alternative. "Like, important men. Rich ones, handsome ones, the ones on TV. Not - I mean, look at me." He gestured vaguely at himself, at his ordinary face, his ordinary build, his entire ordinary self. "I'm nobody. I'm the most average guy alive. Once people actually get to know me, they'll see there's nothing special here, and they'll - they'll relax. The hospital thing was just because I was hurt. People are nice to people who are hurt. That's all it was."

It was a beautiful piece of reasoning. It was wrong in every particular. And Leo, who had built his whole quiet life on the foundational belief that he was nothing special, simply could not see past it - because to see past it, he would have had to believe he might be worth fussing over, and that was a thought he had never once in his life been able to hold.

So he made a plan instead.

He found a notepad in a kitchen drawer and wrote, at the top, in careful letters: RULES.

Then, underneath:

1. Keep your head down. 2. Don't stand out. 3. Blend in. Be normal. Be boring. 4. Don't make a fuss or cause trouble for anyone. 5. Get through the school year quietly and figure out how to get home.

He read it back. It was, he thought with some satisfaction, an excellent plan. It played entirely to his strengths. If there was one thing Leo Evans was world-class at, it was being unremarkable. He'd been training for it his whole life. Other people had to work at standing out; he had to work at the opposite, and he'd never had to work very hard.

He even, feeling slightly ridiculous, practiced in front of the hall mirror. He arranged his face into what he hoped was a perfectly forgettable expression - polite, mild, unmemorable. "Hi," he told his reflection. "I'm Leo. Nice to meet you. Nothing to see here." He nodded. "Yeah. Normal. I can do normal."

His reflection looked back at him, ordinary and earnest and entirely unaware that being the only person in a hundred miles who'd say nice to meet you instead of expecting to be the one impressed was about as normal, in this world, as juggling fire.

That evening, he made dinner.

There wasn't much in the kitchen, but there was enough - some eggs, a few vegetables going slightly soft, rice, a handful of spices in a rack by the stove. Leo cooked the way he always had, easily, without thinking about it much, the way you do a thing you've done a thousand times. He'd learned young, out of necessity, in a house where someone had needed to put dinner on the table and it had quietly ended up being him. Chopping, stirring, the familiar small sounds and smells of it - it steadied him. It was the one thing in this whole upside-down day that felt exactly the same as it always had.

He sat at the little table by the window to eat, and as the light went gold and then grey over the unfamiliar rooftops, the loneliness he'd been holding at arm's length all day finally settled in beside him like an old companion.

He missed home. Not dramatically - Leo didn't do anything dramatically - but in the quiet, specific way of someone who has lost the particular shape of their own life. He missed his duck-shaped water stain. He missed being unremarkable in a world where that simply meant being left alone, instead of this strange new place where it apparently meant the opposite of whatever everyone thought he was. He missed knowing the rules.

"It's just a year," he told himself, scraping the last of the rice from his plate. "Maybe less. Keep your head down, get through it, find a way back. Easy."

He washed his single plate, dried it, put it away. Tidy. Invisible. Leaving no trace, the way he liked it.

It was only when he went to lay out his things for the morning that he found them, folded neatly on the chair in the bedroom where some version of himself must have left them: a school uniform. Crisp white shirt, dark blazer with an embroidered crest - a silver leaf, stitched in pale thread. And tucked into the breast pocket, a letter.

He pulled it out and read it. A welcome letter. Term began tomorrow. Silverleaf Academy looked forward to receiving its newest student.

Leo held the uniform up. The silver leaf caught the last of the light from the window and gleamed.

A school. Of course. A whole building full of teenagers, in a world where he was apparently the rarest thing in it - and he'd already learned, the hard way, exactly how the adults reacted to him. He thought of the game show. Twelve eligible women compete. He thought of the courtyard full of escorted boys. He swallowed.

"It'll be fine," he said, hanging the uniform carefully on the wardrobe door. He said it firmly, the way you say a thing you're trying to make true by saying it. "I'll just - blend in. Sit at the back. Be quiet. Nobody'll even notice the new guy."

He got ready for bed. He set out his shoes by the door. He went over his five rules one more time in his head, and felt better for having a plan, because a plan was a kind of armor and Leo had never walked into anything new without one.

Then he turned off the light and lay in a bed that wasn't quite his, in a life that wasn't quite his, in a world that thought he was a treasure and had no idea he was just a boy, and he told himself, one last time, the most reassuring and least accurate thought he had ever had:

Tomorrow's just a normal first day of school.

He was asleep before he could finish being wrong about it.
