The officer had been speaking for approximately four minutes.
Ji-ho knew this because he had been counting — not to be rude, but because his mind required something to do while the rest of it worked on the problem, and counting the seconds of a lecture he was not hearing was the most efficient available use of the part of his attention he could afford to spare. The officer's mouth was moving. Words were arriving at the general location of Ji-ho's ears. They were not proceeding further.
The office had the institutional quality of a room that had been arranged for authority and then forgotten. Certificates on the walls in matching frames. A desk with neat stacks that were not as neat as they believed themselves to be. A framed photograph of the school's founding that Ji-ho had looked at every time he had been sent here — which had not been often, because he had not been the kind of student who was sent to offices — and which he was looking at now with the same fixed expression he was using to suggest that he was listening.
Through the open door, past the officer's left shoulder, the corridor bulletin board was visible.
He had not looked at it deliberately. His eyes had simply moved, in the way eyes move when they are looking for evidence without being instructed to, and the date had been there: the calendar pinned in the upper right corner, blue border, the month printed in the large font of something designed to be read at a distance.
March 2019.
Ji-ho looked at it for two seconds, then returned his gaze to the officer's face.
The verdict had arrived with very little drama, which was how verdicts usually arrived when the case had already been made and the remaining evidence was a formality. He catalogued what he had: the teacher had reacted — flinched, erupted, gone through the full sequence of a man who had been physically contacted by a student without warning — which meant the teacher was real. The pain had been mutual, or at least Bao Jun-seo had behaved as though it had, which meant the reality was shared. A shared, responsive, physically consistent reality was not a dream; this had been established by philosophers at some point, he was reasonably certain, and it was in any case his working definition. The hand at the end of his arm had been his hand at nineteen. The scratch on the desk had been his scratch from seven years ago.
March 2019.
He was in 2019. The case was closed. The defendant — which was, in an arrangement he had not agreed to, himself — was present.
The officer said something that ended on a rising inflection, which suggested a question.
"I understand," Ji-ho said. "It will not happen again."
The officer looked at him for a moment with the expression of a man who has been robbed of the continuation of his lecture and is not certain how to proceed. Then he nodded, and picked up his pen, and Ji-ho was dismissed.

He found a corner of the corridor between the second and third periods, which was a Tuesday thing — he remembered this, the ten-minute gap that appeared on Tuesdays for reasons that had never been explained and were eventually accepted as one of the school's permanent mysteries — and he took the watch out of his pocket.
The corridor was moving around him, streams of students going in both directions, the noise of seventeen-to-nineteen-year-olds in transit, but Ji-ho had spent six years learning to build a still point inside noise, and he stood against the wall and opened the watch and looked at it with the full, deliberate attention he now knew it warranted.
The etching first. The interlocking leaves across the casing, each one precise, each one overlapping the next, the pattern moving around the circumference in a continuous sequence that had no beginning and no ending and no apparent intention of explaining itself. The same as he had seen in 2026. Unchanged. He ran his thumb along the edge of one leaf and the silver was smooth and warm from his pocket, and this did not resolve anything but it was data.
Then the face.
One hand. Frozen at seven. The hand was fine and dark against the pale face, positioned between the seven and the eight on the right side of the dial, and it had not moved since he had first seen it, which was either because the watch was stopped or because it was not the kind of watch that moved in the direction of less.
He looked at it for a long time.
Seven years back. The hand at seven.
Ji-ho was too careful a thinker to announce this as a conclusion — he had seen enough arguments collapse from the weight of a too-early inference — but he held it as a hypothesis, which was a different thing: provisional, noted, pending further evidence. The hand said seven. He had traveled seven years. This might be a coincidence, and he was not, professionally or temperamentally, inclined to trust coincidences; but it might also be a characteristic of the mechanism rather than an instruction, and the difference between those two things was material and he could not yet determine it.
He turned the watch over.
The gap where the winding crown should have been was still there, still clean, still the precise circular absence of something that had been removed rather than lost. He put the pad of his thumb against it and felt the smooth rim of the gap and thought about what it meant to have a watch with no mechanism for winding it, and what it meant that someone had removed that mechanism deliberately, and what it meant that the watch had apparently functioned regardless.
He did not reach a conclusion. He filed the gap under the same heading as the seven and the leaves and the silver that should have belonged to another century: things he had observed, things that would need to mean something eventually, things he did not yet have enough information to understand.
*(He attempted, standing in the corridor, to map the logical architecture of what had happened to him — the transfer, the body, the seven years, the particular question of what he was supposed to do with the information he now possessed. He got approximately two and a half steps into this mapping before encountering what he could only describe as resistance: a quality of the thinking itself, a slight but unmistakable friction in the process of assembling complex inferences, as though the instrument he was using to think with had a smaller working capacity than the one he was accustomed to. His nineteen-year-old brain was, it appeared, a less efficient processor than his twenty-six-year-old brain had been. This was not a complaint he had any mechanism for filing. He noted it with the dry, contained resentment of a man who has discovered that the car he has been given for an important journey has a smaller engine than advertised, and put the watch away.)*

History was first, after the break.
The teacher — not Bao Jun-seo, who taught a different period, but a younger woman whose name Ji-ho was in the process of recovering from wherever he had stored it — asked the class to name the primary causes of the 1894 Donghak Peasant Revolution.
Ji-ho knew the answer. He had known the answer before the question had finished forming in her mouth — not because he had studied it recently but because he had studied it here, in this classroom, with this teacher, and the knowledge had been sitting in him for seven years with nowhere in particular to go. He looked at his desk. The question finished. A boy in the second row raised his hand and gave approximately sixty percent of the answer, haltingly, and the teacher nodded with the encouragement of someone who has learned to treat partial credit as a form of progress.
Ji-ho said nothing.
This was going to require a particular kind of discipline, he understood — the sustained, active labor of performing ignorance when the answer was already there, fully formed, waiting. It was not unlike the discipline required in depositions, when you knew where the argument was going and had to appear not to know, except that in depositions the performance served a purpose and here the purpose was simply to not attract the kind of attention that a seventeen-year-old who answers every question with the precision of a first-year associate would inevitably attract. He had attractd enough attention for one day. The pinch had seen to that.
The class moved through its questions. Ji-ho moved through the class, answering two he had not been called on for — both times catching himself a half-second too late, the answer already in the air before the discipline could stop it — and declining two he was called on for directly, both times producing expressions of mild teacher-disappointment that sat on him with the specific weight of something not deserved but not worth contesting.
From three rows over, someone's bag made a sound that was apparently very funny. Ji-ho did not track what it was. Around him the classroom's social weather moved in its ordinary teenage patterns — whispers, notes, the particular economy of a room full of people for whom the lecture is one of several things happening simultaneously — and Ji-ho watched it from behind his expression of appropriate student attentiveness with the detachment of someone watching a documentary about a country he used to live in and found, in retrospect, very small.
At some point during the third class, the teacher paused in the middle of a transition between topics and said, in the tone of someone who has been waiting for a natural opening, "Mr. Kang, I trust we won't have a repeat of this morning's conduct."
Ji-ho looked at him.
"I trust so as well," he said.
The teacher held his gaze for a moment, apparently looking for the irony, apparently not finding it in a location he could act on. He moved on. A girl in the front row turned around and looked at Ji-ho with an expression he could not immediately decode and then turned back. Two boys in the row behind him exchanged a look that he did not need to see to know the content of.
The lesson continued.
By the end of the last class, Ji-ho had answered three questions he had not been called on for, declined to answer two he had, and spent the better part of two hours watching his classmates navigate a world that was entirely adequate for what it was and for which he was, in every practical sense, overqualified. The teacher had mentioned the incident with Professor Bao Jun-seo twice more, in two different registers — once as a general comment on classroom conduct and once, more pointedly, at Ji-ho directly. Ji-ho had not acknowledged either mention, which he understood was its own kind of answer, but it was the answer he had available and he was working with the materials at hand.

He walked out of Hansol High School at four-fifteen in the afternoon.
The bag on his shoulder was his bag — or rather, it was the bag of the person whose body he was currently occupying, which were the same person, which was a sentence he was not yet confident he could think all the way to the end without the friction returning. He walked through the front gate with the particular step of someone who is exiting a building and not fleeing it, and the March air met him at the threshold and was the same as it had always been: cool, faintly exhausted, carrying the particular quality of a Seoul afternoon that has not decided whether it is winter or spring and has settled on both.
He stopped on the pavement and took one breath.
The watch was in his pocket, the single hand frozen at seven, the gap in the casing clean and circular and patient. Seoul in 2019 moved around him in its ordinary afternoon rhythm — students, parents, the sound of the streetcar somewhere to the north, the city conducting itself without any awareness that it was seven years behind where he had last seen it.
It did not know it was missing anything.
Ji-ho stood on the pavement for another moment, and the city did not notice, and then one thought arrived — the way his best thoughts always arrived, not dramatically but with the quiet authority of something that had been assembled correctly — clear and economical and offering exactly as much comfort as the conclusion of a brief offers, which was none, but also exactly as much direction:
He was going to need more information.
It was, he acknowledged, a start.
