The day after I answered, I came to receive the reply.
January 5th. Yesterday I had pressed the ㄱ of Min-seok's name into the sender field. Something was sent, and there, nothing happened. The answer would be received by the next person — so I had written. But the next person had not yet come, and so the answer came to me first.
I turned on the terminal. I opened tomorrow's roster. I looked first at the place where Min-seok's firm's name had stood. The name was whole again. Its syllables held together. The name that had been splitting yesterday had come back, today, as one person. On the roster his line had been erased. It was a place that had survived.
For a moment I felt something I nearly called relief. The answer had saved him. Just as I began to think it, my eye slid one cell down.
Right beneath the place where Min-seok's name had stood, another line was beginning to split. It had been a whole name until yesterday. Today, for the first time, the last letter of that name was coming loose into syllables. By exactly as much as Min-seok's name had returned, the line beside it was coming undone.
I looked from one line to the other. One had closed; one had opened. The amount closed and the amount opened were the same. As if the weight gone from one seat had not vanished but moved to the seat beside it. The answer was not a saving. The answer was a relocation. I had not erased Min-seok's line; I had copied his share over onto the person next to him.

The sum beneath the ledger did not decrease. It had never once decreased. All I had done was change, within that sum, who sat in which line. To say "save" was the wrong word. To say "move" was right. I was still one who copies out, and this time I had copied out a person.
The name beside it had not fully come loose. Only one last letter had fallen; the rest still held. I knew that if I read that name to the end, I would learn whom I had seated in that place instead of Min-seok. I brought my finger up to the screen. But this time I knew — that to read to the end is to fix that seat. Read it and it spreads. One letter still remained. Before that one letter, as yesterday, I stopped.
Yesterday I stopped before one letter. Today, though I had not read it, the letter had fallen.
January 6th. Even before I turned on the terminal I knew it: that stopping stops nothing. The moment I pressed the sender field yesterday, the seat was already fixed; my not reading the name to the end meant only that I had wished to stay without knowing it. The seat fills whether or not I read it. I should have set that down, in one line, over yesterday's hesitation.
I opened the roster. Min-seok's line stayed erased, as yesterday. Beneath it, the name that had shed only its last letter until yesterday was closed today into one whole person. The fallen letter had not gone back; rather the remaining letters had been drawn into the place it left, making one new name. A person sat there.
I took yesterday's printout from the drawer and laid it beside today's. The digits of the insolvency that Min-seok's firm should have borne — yesterday I read them on his line. Today those digits were not on his line. They were on the line beside it. One place at a time, from the last digit up, exactly as much as had drained from Min-seok's line yesterday had grown on the line beside it. The weight gone and the weight grown were the same. The same down past the decimal point.

The number beneath the ledger does not decrease. It was so from the very first box. That number, which grew each time it was set down, now grew on another line whenever I closed one. I could move the place where it grew; I could not stop the growing itself. I had not saved Min-seok; I had copied his share onto the back of the person beside him. And that person beside him had been, until yesterday, a whole name with no danger at all.
The word save slipped from my hand. The word move came and sat in its place. As Min-seok's name yesterday had pushed the neighboring line aside and sat back down in its seat.
The neighboring name was fully read now. I had shut my mouth to keep from saying it aloud, but my eyes had already read it to the end. It was a name I had seen somewhere. Whether in the register of one firm among the transferred boxes, or someone Min-seok had once named in passing, or a line I had brushed past while ordering the fifth bundle. I did not know that person. And yet that person's seat was now one I had fixed.
I remembered the thing I had nearly called relief yesterday. Whose share that relief had cost — yesterday I had not known, and today I did. But the thing I most needed to know — whether it was right to have saved Min-seok, whether it was wrong to have taken the one beside him — that alone was set down nowhere in the ledger.
I came wanting to know whom I had saved. But the ledger writes the one saved and the one taken in the same ink.
January 7th. I spread three days of rosters on the desk. The 5th, the 6th, the 7th. Tracing Min-seok's line and the line beside it with my finger, I tried to find which had moved first. Whether Min-seok's digits had drained first and the neighboring line had grown after, or whether the neighboring line had grown first and Min-seok had been emptied by its growing. If I could divide cause from effect, I thought, I could know what I had done.
I could not divide them. The rise and fall of the two lines had happened on the same date, in the same place, by the same magnitude. There was no first. It was like the lighthouse keeper's tide — whether the water rises because it is measured, or is measured because it rises, the order was written nowhere in the log. I could read what had happened; I could not read what would not have happened.
I looked again at the neighboring name. The name I had read to the end yesterday. I decided to find the person. I searched the registers of the transferred boxes. There it was — the treasury desk of one suspended firm, the same rank as Min-seok, the same years in. Whether there was a child, a loan, a house — the register did not go that far. But that whatever Min-seok had, this one had too, I could know without its being written.
So I had seated one treasury clerk in the place of another. The two were alike. Of two alike lines I had chosen to close one and open one. On what ground had I chosen? Min-seok was a person whose name I knew; the one beside him was a person whose name I had not known. That was all. The known name had pushed out the unknown.
If the one beside him had been a line meant to fall from the start, and Min-seok's brief reprieve was the thing out of place, then I had set right what was out of place. If Min-seok had been the line meant to fall, then I had dragged a sound person into that seat. Which of the two it was, the ledger does not write. The ledger writes only that the sum is the same. As long as the sum is the same, who bears it is, to the ledger, the same thing.
That I could not know, I had in the end to accept. But the moment I accepted it, another thought slipped in. If I could not know — there was only one way to find out. To answer once more. If I laid a hand on the neighbor's line, and watched where its weight moved next, perhaps I could guess which line the law held to be the rightful seat.
I set down the pen so as not to write that thought. But that setting down the pen does not stop the thought, I had learned only yesterday, before one letter. My hand was already asking. Would I not know, it asked, if I pressed once more.
