Donghyun had been Inha's closest friend since their second year of university, which meant he had accumulated twenty-two years of evidence and had never once needed more than forty seconds to determine when Inha was managing something he had not decided to name yet.
He called on Sunday at noon, which was his standard check-in time, the call he made every week the way some people watered plants, and Inha answered from his desk where he had been working since eight AM on the load specifications for a municipal project in Yeongdeungpo that did not require his personal attention but had a structural problem he found interesting.
"You sound different," Donghyun said, by way of greeting.
"I'm working."
"You always sound the same when you're working. You sound like someone reading a technical document. This is a different sound."
"I don't have a different sound."
"You have a slightly less flat sound. It's very subtle. I only notice because I have known you for twenty-two years and you have been consistently flat for most of them." A pause, during which Inha could hear the particular ambiance of wherever Donghyun was, which sounded like a café with a door that opened onto a street. "Did something happen."
"I'm taking someone to my mother's dinner on the fourteenth."
The pause that followed was four seconds long.
"A someone," Donghyun said carefully, "or a someone someone."
"Her name is Seo Yuna. She works at my firm. It is an arrangement."
"An arrangement," Donghyun repeated, in the tone he used when he was adding information to a file he intended to return to. "What kind of arrangement."
Inha had prepared for this question in the way he prepared for most things, which was to consider the true version and the version that would close the inquiry, and decide which one served the situation. He had decided, somewhere between Friday evening and Sunday morning, that the true version was cleaner.
"My mother has been managing introductions at four consecutive family events," he said. "I asked Yuna to come to the Bundang dinner as my girlfriend. She agreed. It ends when my mother accepts the situation and stops."
"And Yuna agreed to this."
"She did."
"Why Yuna specifically."
Inha looked at the load specifications on his screen. The Yeongdeungpo building had an unusual cantilever on the third floor that the original architect had compensated for in a way that worked but was not the most elegant solution, and he had been thinking about a cleaner approach since Tuesday, and the question Donghyun had just asked was the same question Yuna had asked him in the coffee shop, and his answer now was not the same as his answer then.
"She doesn't perform," he said.
A pause. "That's the professional answer."
"It's also the true answer."
"Those are not always the same thing."
Inha did not respond to this. Outside his window Seoul was conducting its Sunday business, the quieter version, the version that ran on coffee shops and park benches and the particular unhurried quality of a city taking a morning off from itself.
"How long have you been noticing her," Donghyun said, in the tone of a man who already knew the answer and was asking out of courtesy.
"Fourteen months."
Another four-second pause. "Inha."
"It is an arrangement."
"You have been noticing a specific person at your firm for fourteen months and you asked her specifically, not someone else, and you are taking her to your family's home in nine days and you are telling me this is an arrangement."
"Those things are not contradictory."
"No," Donghyun said pleasantly, "they are not contradictory. They are a very specific sequence of events that a person who was better at being honest with himself would describe differently." He paused again. "Is she coming to my marathon."
"You have not run the marathon yet. You have started training for it four times."
"This is the time I finish it. February. And she should come, if she's going to know you, because watching you watch me run is the most human I have ever seen you look."
"I do not watch you run."
"You stand at the twelve-kilometre mark with water and an expression that is as close to anxious as your face gets. It is very touching. Yuna would find it useful."
Inha looked at his desk. The glass of water at his elbow had been there since eight AM and he had not touched it, which was a habit he had that he had never managed to resolve, setting water down and then simply not drinking it, a kind of inattention toward his own needs that he recognised but did not particularly address.
"It is an arrangement," he said again.
"I know," said Donghyun. "I heard you the first time. I am simply noting, for the record, that the last time you made a purely functional decision about a person, you did not mention them four times in a Sunday phone call." He paused. "How is the marathon training."
"You started three weeks ago."
"Six weeks. I started six weeks ago. I am at fourteen kilometres."
"That's two weeks of progress."
"It is six weeks of progress at a rate that reflects my other commitments." A brief silence. "She's going to change things. That is not an accusation. It is an observation about the look on your face when you said her name."
"I did not say her name with a particular look."
"You said it the way you talk about buildings that interest you." Donghyun's voice had the quality it got when he was being precise about something he found important. "You know. The way you say a project has a problem worth solving. Not like a difficulty. Like a thing that deserves attention."
Inha was quiet.
"It is an arrangement," he said, for the third time, which was once more than he had intended to say it, and which told him something he was not going to write down.
"Of course it is," Donghyun said agreeably, in a register that was familiar enough to be irritating. "Send me the marathon training app I asked for two weeks ago. And bring Yuna to the twelve-kilometre mark in February."
He hung up.
Inha sat at his desk for a moment, looking at the Yeongdeungpo cantilever and not seeing it, and then he picked up the glass of water that had been sitting at his elbow since eight AM and drank half of it, because some things were worth attending to before they went cold.
He sent the marathon app link at twelve seventeen. He looked at his phone for a moment after, at the conversation thread with Yuna, which contained her document and his reply and nothing else. He read his reply again: Everything in this is useful. Thank you.
He had deleted the first draft, which had said: Received. I know it.
He had deleted it because it was too direct, and he was not yet in a position to be that direct, and he was aware of the distinction between those two facts.
He put the phone down. He returned to the cantilever.
At two PM he sent Yuna the Bundang address and the time, six thirty PM on the fourteenth, and added: My mother's name is Kang Jungsook. She will offer you tea before anything else. Accept it.
The reply came eleven minutes later: Noted. What kind of tea does she make.
He looked at this for a moment.
Barley tea, he wrote. She makes it herself.
A pause. Then: All right.
He put the phone down again and looked out the window at Seoul going about its Sunday afternoon, and thought about a woman writing a thesis about load-bearing pasts, and the way she had looked at the river this morning, and the way Donghyun had said: the way you talk about buildings that interest you.
He did not write any of this down.
He finished the cantilever calculations instead, which was useful, and correct, and required his full attention, and took him until six PM, by which time Seoul had moved from afternoon to the early-dark of a rainy season evening and the work was very good and he was satisfied with it.
He was also, underneath the satisfaction, aware of a specific and inconvenient warmth that he had no intention of naming until it became unavoidable.
It was not yet unavoidable.
