March 3. Seven in the morning. I turned the terminal on two hours early.
Yesterday's single line was still there in the body. Kang Min-seok's number. I had not moved it yesterday, and a line left unmoved does not go away. Leave it, and the vertical line reaches it; once the vertical line reaches it, the number goes up on the nine o'clock notice. Two hours to nine. Two hours I had bought by coming in early.
I thought about what two hours could hold. Move his line into the sending column and my hand closes him. Leave it and the arithmetic closes him. Both roads ended at him. But for three days I had moved his circle and sent the sum somewhere else. What I had run out of was circle, not the sending. If his was the only line in the body, then perhaps I could write into the sending column a line the body did not hold. Write a number that was not his, and perhaps the sum would close that other number and leave his line standing.
The thought was not new. Every one of those three mornings, choosing the furthest line meant also choosing which lines I would not move, and that was already sending the sum to a seat of my picking. If I decided where it went, I could send it past the body altogether. With only Min-seok's line left, sending the sum outside the body was the one road that did not end at him.
I picked the number. Not his. Someone on another floor, not Treasury, a face and a name I did not know. I called up that one unfamiliar number and wrote it into the sending column, character by character, hoping it would close and his line would stand.
The moment the last character went down, the one line in the body became a result.
What I had written in the sending column did nothing to the line in the body. The sending column was the answer; the body was the dictation. Write the answer and the dictation becomes a result — I had done exactly that for three days without once seeing it from this side. The numbers I closed over those three days did not close because they sat in the sending column. They closed because they sat in the body. Moving a line meant copying it out of the body into the sending column unchanged, so both fields carried the same number every time. Being the same, there was never any reason to ask which one did the closing.
Today I wrote into the sending column a number the body did not hold. It made no difference. What became a result was the line in the body. An answer went down, the dictation turned into a result, and the dictation was Min-seok. The arithmetic never asked what the answer said. It asked only whether one had been given, and when one had, it closed the line standing in the body. I gave an answer. The line was his.

For three days I had believed the sending column closed a seat. Write a number there and that number closed, so the closing was the column's doing. It was not. What closed was the body, at the instant an answer appeared in the column. What I had closed over those three days was never the number I chose; it was whichever seat that number happened to occupy in the body. What I took for choosing was not choosing. The body set the line and I decided only whether to answer it. The arithmetic had been in the body the whole time, and I stood outside it, answering. For three days the hand that thought it was choosing who to keep and who to close had been choosing nothing but yes or no to a line already set.
Before nine I tried to erase the number in the sending column. It would not go. What was written stayed written, and his line stayed a result.
Nine o'clock. The personnel notice went up. Headcount reduction for March 3, one seat, Treasury. It was Min-seok.
To keep from closing him I had written a number that was not his, and writing a number that was not his closed him. The hand that meant to stop it was the hand that did it. For three days I had blocked, knowing blocking had an end and that the end was him, and this morning the last gesture of blocking pulled that end forward. Left alone, the nine o'clock notice would have taken him. Because I moved, my seven o'clock hand took him instead. All my blocking did was bring the seat forward by two hours. The hand that meant to buy two hours spent them.
Later that morning I went up to Treasury. Treasury was empty. Among the desks that had gone one a day for three days, his was the last to go. The seat where he had sat alone yesterday, in the middle of all that emptiness, had no one in it. A section takes days to empty. The last seat took two hours, and those two hours were the ones I spent trying to save him.

His desk had not been cleared the way he had cleared his colleague's the day before. There was no one left to clear it. No mug taken away, no hand to move the navy coat off the back of the chair. Clearing an empty seat always falls to whoever stays, and in Treasury nobody had stayed. An uncleared seat keeps its person longer than a cleared one does.
The last thing he said was, I'm next. He said it yesterday among the empty desks, and I had already read it in the body. If his guess had left him a day, this morning I cut that day to two hours. His next turned out to be today, and I was the one who moved it to today. He never learned when his next was. I was the hand that brought it forward. His blind guess and my knowing gesture met on the same day, in the same seat.
I went back to my desk and looked at the body. Where his line had become a result and gone, a new line was being written. I read the first two characters. Not Treasury's code. The archive's.
While the last two digits were still coming, I knew what they would be. There was only one number in the archive whose last two digits I knew by heart. Not one I copied twice a month, not the number of someone I passed in the corridor. The one I held in my own hand every day, wrote into my own memo pad and my own sending column every day. Mine.
The line finished. The last two digits were mine. For three days — from before that, really — I had thought I was emptying a circle to leave one person standing at its center, and I had thought that person was Min-seok. Only when my own line came up in the place his had left did I understand who had been standing there.
Emptying a circle is leaving a center, and at the center of every circle is the seat the emptying hand stands in. I thought I had held him at the center and cleared his ring. But the seat that hand stands in is the center that lasts longest. A hand that picks which seat closes will not itself go unclosed — I may have known that from the day I wrote that no hand is a still hand. The new line in the body was my number, and the hand that would move it and the hand that would leave it were the same hand the number belonged to. Tomorrow morning, if that hand writes an answer in the sending column, the line becomes a result. Keep the hand off, and the vertical line reaches it. Move it and it is me; leave it and it is me.
