Chapter Text
The faculty mixer smelled like cheap wine and expensive anxiety. Changkyun stood near the sculpture garden terrace, nursing a glass of something red that tasted like regret, and wished he'd stayed home. His first week at the university had been a masterclass in social inadequacy—he'd already managed to confuse two department meetings, call a senior colleague by the wrong name, and give a lecture so dense three students had fallen asleep.
"You look like you'd rather be anywhere else."
Changkyun turned to find a man leaning against the terrace doorframe—tall, broad-shouldered, with the kind of casual confidence Changkyun had spent his entire academic career trying to fake. He wore clay-stained jeans and a white button-down with the sleeves rolled up, dark hair falling into eyes that seemed to catalogue everything they saw.
"Is it that obvious?"
"You've been standing in the same spot for twenty minutes, and your body language screams 'please don't talk to me.'" The man stepped onto the terrace properly, closing the distance. "So naturally, I'm talking to you."
"Perverse," Changkyun observed.
"I prefer 'curious.'" He extended a hand. "Son Hyunwoo. Sculpture."
"Im Changkyun. Economics." The handshake was firm, warm. Changkyun noticed clay under Hyunwoo's fingernails, the calluses on his palms. Hands that made things. "You're allowed to leave events like this covered in clay?"
"Tenure has its privileges." Hyunwoo's smile was slight but genuine. "Besides, I came straight from the studio. If I'd gone home to change, I wouldn't have come back."
"Smart."
"Self-aware." Hyunwoo leaned against the railing beside him, close enough that Changkyun could smell clay and something else—cedarwood, maybe. "First week?"
"That obvious too?"
"You have the haunted look of someone who just realized faculty meetings are worse than dissertation defenses."
Changkyun laughed despite himself. "I thought once I finished my PhD, the performance anxiety would end."
"It doesn't. It just changes shape." Hyunwoo took a sip of his own wine, made a face. "This is terrible."
"Objectively awful," Changkyun agreed. "I've been trying to calculate the optimal number of sips to seem social without actually drinking it."
"And?"
"The optimal number is zero, but the social cost of not drinking is higher than the utility loss from bad wine."
Hyunwoo's laugh was unexpected—rich and genuine, transforming his entire face. "You talk like an economist."
"I am an economist."
"No, I mean—" Hyunwoo gestured vaguely. "You process everything through frameworks. Cost-benefit analysis for wine consumption."
"And you don't?"
"I throw clay at a wheel and see what happens."
"That sounds terrifying."
"It's liberating." Hyunwoo turned to face him properly, and Changkyun felt the weight of his attention like a physical thing. "You make everything a puzzle to solve. What happens when there's no solution?"
"I find one anyway."
"What if the puzzle is the point, not the solution?"
Changkyun opened his mouth to respond, then closed it. The question sat in his chest like something alive. "Is that what sculpture is? Puzzles without solutions?"
"Sometimes. Mostly it's about negative space—what's not there shaping what is."
"Like game theory."
Hyunwoo's eyebrows rose. "Explain."
So Changkyun did. He explained Nash equilibrium and dominant strategies, how what players don't do is as important as what they do, how absence creates structure. And Hyunwoo listened—actually listened, asking questions that proved he was following the logic, making connections Changkyun hadn't expected.
"So you're saying," Hyunwoo said slowly, "that the space between actions determines the outcome as much as the actions themselves."
"Exactly."
"We're talking about the same thing." Hyunwoo's smile was different now—warmer, more open. "Just different languages."
They talked for two hours. Changkyun forgot about the party inside, forgot about his awkward first week, forgot to be anxious. Hyunwoo had a way of asking questions that made Changkyun's thoughts sharpen and clarify, and when Changkyun returned the favor, Hyunwoo spoke about art with the precision of someone who'd thought deeply about why they created.
"There you are!"
They both turned to find a woman striding toward them—petite but commanding, with sharp eyes and a sharper smile. She wore a black dress that probably cost more than Changkyun's monthly rent and carried herself like someone who'd never doubted her place in a room.
"Nayeon-ah," Hyunwoo said, affection clear in his voice. "I was wondering when you'd find me."
"I've been looking for both of you." She turned to Changkyun, and her expression softened into something complicated—love and exasperation and pride all tangled together. "Changkyun-ah."
"Noona." Changkyun felt himself shift into baby brother mode automatically—shoulders relaxing, smile easier. "The party's nice."
"Liar. You've been hiding." She looked between them, something calculating in her gaze. "But I see you've met my best friend."
The world tilted slightly. Changkyun looked at Hyunwoo, who was looking at Nayeon, and the pieces rearranged themselves into a much more complicated picture.
"This is your brother?" Hyunwoo asked, something careful in his voice.
"My baby brother," Nayeon confirmed, reaching up to fix Changkyun's collar even though it was fine. "The genius who forgets to eat lunch."
"I'm twenty-eight, not twelve."
"And yet." She turned to Hyunwoo. "Make sure he doesn't hide in his office all semester, okay? He needs to actually socialize."
"I socialize," Changkyun protested.
"Emailing doesn't count." Nayeon's phone buzzed. She glanced at it, sighed. "Dean Park needs me. You two play nice."
She swept back inside, leaving them in weighted silence. Changkyun became hyperaware of how close they were standing, how the last two hours had felt like something more than a conversation between strangers.
"Your sister," Hyunwoo said carefully, "is protective."
"That's one word for it."
"She talks about you a lot. The brilliant baby brother with the MIT PhD."
Changkyun's chest tightened. "What else does she say?"
"That you're adjusting to your first real job. That you need time to settle in." Hyunwoo's expression was unreadable. "That I should look out for you."
"I don't need looking after."
"I didn't say you did." Hyunwoo pushed off the railing, and Changkyun felt the loss of proximity like a dropped connection. "But she's my best friend. Has been for eight years. So I'm going to respect what she asks."
"Which is?"
"To let you settle in without complications." Hyunwoo's eyes met his, and Changkyun saw understanding there—and regret. "I should go. It was good talking to you, Professor Im."
The formality stung. "Professor Son."
Hyunwoo walked away, and Changkyun stood alone on the terrace, his wine now warm and even less appealing. Inside, he could see Nayeon laughing with a group of senior faculty, Hyunwoo joining her, her hand on his arm in casual affection.
His sister's best friend. Of course. Because Changkyun's instincts were always catastrophically bad at reading social situations, and apparently that extended to being attracted to exactly the wrong person.
He drained his terrible wine and went to find another glass.
