Taemin was already on the steps when Kael got to them, eating something from a paper bag and reading something on his phone, in the attitude of someone who had been there long enough that the steps had become his.
"Im Changsoo," he said, without looking up.
Kael sat.
"Construction and development." Taemin turned his phone over and set it down. "Three buildings in mid-Solan, two more permitted. He broke ground on the second one last spring — there's a billboard on the Yongsan overpass, big photograph, him shaking hands with someone from the city planning office." He took something out of the paper bag. "There's a plaque in the school's east corridor. The new science wing. Generously supported by Im Changsoo and the Im Family Foundation." A beat. "It's a nice plaque. Brass. Very permanent-looking."
"The vice principal," Kael said.
"Twice for lunch, that I know of. Could be more." Taemin ate thoughtfully. "The school has a formal complaints process for bullying. Seven complaints have been filed about Sungho since he started here. Three of them involved scholarship students. One of them involved a teacher." He paused, and the pause had a shape to it — the shape of someone arriving at the last fact and placing it carefully. "He has never been formally disciplined. Not once. Not a letter home. Not a conversation."
The courtyard below them was half-full, students moving through it in the patterns of people with somewhere to be and fifteen minutes to get there. Kael watched a group of year-ones cut across the far corner.
"How do you know about the complaints?" he said.
"Min Haewon in 2-C was one of them. She told me." Taemin folded down the top of the paper bag. "She thought telling someone would matter. She found out it didn't."
A beat.
"She's not wrong to have thought that," Kael said.
"No." Taemin looked at him then — direct, briefly, the way he'd looked on the steps outside the library the day before, the look that arrived and left before it could be examined. "She's not."
They sat for a moment in the way they had developed, apparently without discussing it, of sitting — Kael not filling silences, Taemin not needing him to. Below them, a teacher crossed the courtyard with a stack of papers and the expression of someone who was running slightly late and refusing to show it.
"Sungho's going to university next year," Taemin said, picking up his phone again. "A good one, probably. His father made a call, probably. He will leave this school and go somewhere else and he will be exactly this person there, because no one has ever given him a reason not to be."
"What about Jiho," Kael said.
Taemin looked at his phone for a moment without reading it. "Jiho has two more years here." He turned the phone face-down. "He's very good at maths. There's a scholarship for the university exam — competitive, but he has the marks for it. If he can keep his marks up." A pause that carried its own implication. "Sungho tends to be disruptive during exam periods."
Kael said nothing.
"I've been watching this for a while," Taemin said, lightly, in the same tone in which he said most things. "I'm not — I don't know how to do anything about it. I just watch and know things, which is useful and also completely useless." He stood up, brushing crumbs from his uniform jacket. "So I thought I'd tell someone who might know what to do with knowing things."
He went back inside. Kael stayed on the steps and looked at the courtyard and thought about the structure of what Taemin had just said — not the content but the architecture of it, the way it had moved from surface to mechanism to consequence without once editorializing, the seven complaints delivered in the same register as the building permits. The information had been ordered to do a job. The job was: make the conclusion unavoidable without naming it.
It had worked.
The Yuna encounter happened on the way to fourth period, in the main building's second-floor corridor, and it happened entirely because she was coming the opposite direction at speed and almost walked into him before pulling up short with the particular grace of someone whose reflexes had been trained for exactly this kind of close-quarter adjustment.
"Sorry," she said, not sounding particularly sorry — more amused. She looked at him. "You walk like you expect the corridor to get out of your way."
"Most people do," he said.
"Most people also make eye contact sometimes. As a social courtesy."
"I was reading."
She looked at his hands. He was not holding anything.
He said nothing. She was quiet for exactly the length of time it took to decide something, and then the corner of her mouth moved.
"My father mentioned your father last night at dinner," she said. "He called him formidable, which from my father is the highest possible compliment and also possibly a mild threat."
"My father says the same thing about yours."
"Really?"
"He says it while sounding like he means it as a compliment."
She laughed — short, real, caught slightly off guard. He watched it happen and then looked at the corridor ahead because that was where he was going, and she stepped to one side and he passed her and continued to class, and it was only somewhere around the point when he was settling into his seat that he realized he had said something that was not minimum — had said it without calculating whether to say it, which was different. He sat down.
Im Changsoo's corporate structure took forty minutes after dinner to map properly, which was longer than he'd expected given that the surface of it was clean. Three construction companies, one holding entity, a family foundation with a website that was mostly photographs of Changsoo shaking hands with people at buildings. The permits were filed. The taxes were paid. The accountant was very good.
But the holding entity had a subsidiary. And the subsidiary had, two years ago, entered into a joint land-acquisition agreement with a development company called Saehan Partners — a name that appeared, small and unremarkable, at the outer edge of the web he had been watching for three weeks.
Not inside the web. Adjacent to it. One step removed.
It might be nothing. Two companies sharing the edge of a land deal was not evidence of anything except that Solan's development sector was smaller than it looked from the outside, and that money moved in circles, and that coincidence was the most common explanation for most things.
He wrote the name in the margin of his notebook, drew a line from it to the map already on the page, and put a question mark at the end of the line.
Then he closed the notebook and shut off the secondary monitor and went to get his jacket.
The scholarship housing block sat behind the school's gymnasium, separated from it by a service road and a row of birch trees that hadn't finished losing their leaves. Two storeys. Twelve units. External staircase with a light on the upper landing that worked and one on the lower landing that didn't. The building wasn't neglected — the windows were clean, the entry buzzer panel had all its buttons — but it had the look of a place that was functional by design rather than cared for by habit. The kind of building that existed to fulfil a purpose rather than to be somewhere people felt at home in.
He stood in the shadow of the birch trees for twenty minutes. It was cold enough that he could see his breath. A woman left from the upper floor — not a student, thirties, in a coat, keys in hand — and walked south toward the main street. A group of three students came back together just after nine, talking, backpacks on, the particular energy of people returning from a library or a study hall. He watched them go in.
At nine-seventeen, a light came on in the ground-floor corner unit.
He watched the window for a while. The light was steady, not the moving quality of a television — a desk lamp, probably. Someone sitting at a desk, working, the same as he did, in the same hours.
After another ten minutes, he left.
He knew which unit. He knew the building's layout, the sight lines from the upper floor, the single entry point, the service road that ran along the east side. He knew that Sungho's pattern — from what Taemin had described and what he'd observed himself — was deliberate and targeted and had continued for at least two years without consequence.
What he didn't know yet was whether it lived only in the school or whether it followed the walk home.
He had a route and a residence now. The rest was time.
He walked home through the birch trees with his hands in his pockets and the cold on his face, and by the time he reached the house he had the shape of the next two weeks mostly drawn. Not finished. You didn't finish the picture until the picture finished itself. But the outline was there.
His mother was still up, reading at the kitchen table with a cup of tea and the particular stillness of someone who was aware of everything in the room and attending only to the book. She didn't look up when he came in.
He poured a glass of water. Drank it at the counter.
"Cold out," she said, still reading.
"Yes."
A page turned.
He put the glass in the sink and went upstairs.
