Chapter 53: Park Hajun
The baby arrived three weeks early, on a Tuesday in November 2012, while Dojun was in the middle of a board meeting with David Yoo about Series C strategy.
His phone vibrated. Hana’s name on screen. She had stopped working the previous week—”maternity leave, designer-style: I’ll still review wireframes from bed but I won’t come to the office”—and was at home in Seocho-dong, theoretically resting.
“Excuse me,” Dojun said to David, who was mid-sentence about Asian market expansion. “My wife is calling.”
“It’s time,” Hana said. Her voice was calm—too calm, the calm of someone who had moved past panic into pure operational mode. “My water broke. I called a taxi. I’m going to SNU Hospital. Meet me there.”
“I’m leaving now.”
“Don’t run. Don’t crash. Don’t do anything dramatic. Just come.” A pause. “And call your mother. She made me promise she’d know before the contractions get serious.”
He hung up. David Yoo looked at him.
“The baby?” David asked.
“The baby.”
“Go. The Series C will wait. Babies don’t.”
Dojun grabbed his jacket and ran—he ran, despite Hana’s instruction not to—through the Gangnam office, past thirty desks of people who watched their CEO sprint through the building, out the door, into a taxi that he directed to SNU Hospital with the particular urgency of a man who had waited sixty-eight years, across two lifetimes, for this exact moment.
He called his mother from the taxi.
“It’s happening,” he said.
“NOW? But she’s three weeks early!”
“Babies don’t follow schedules.”
“AIGOO! I’m closing the stall. Mrs. Kang! Watch my banchan! My grandchild is coming!” He could hear the market erupting in the background—Mrs. Kang shouting instructions, Mr. Song offering to drive, the entire banchan alley mobilizing for the arrival of Park Younghee’s first grandchild.
“Mom. Take the subway. Don’t let Mr. Song drive. He drives like he butchers meat—fast and imprecise.”
“I’ll be there in forty minutes. Don’t let the baby come before I arrive!”
“I don’t think I have control over that.”
“You’re a CEO. Negotiate.”
Park Hajun was born at 6:47 PM, weighing 2.9 kilograms, with a full head of dark hair and a cry that the delivery nurse described as “healthy” and that Dojun, standing beside Hana, holding her hand, tears streaming down his face, could only describe as the most important sound he had ever heard.
Hana held the baby first. She looked at him—at this tiny, wrinkled, impossibly real person who had been a concept and a spreadsheet entry and a design project for nine months and was now, suddenly, irrevocably, a human being with fingers and toes and a voice—and said:
“He has your eyes.”
“He has your everything else.”
“Good. My everything else is better designed.” She was crying and laughing simultaneously. “Hello, Park Hajun. I’m your mother. I designed you.”
“You didn’t design him.”
“I designed everything else in my life. He’s the only thing that designed himself.” She looked at Dojun. “Hold him.”
He took the baby. Hajun—the name they had chosen together, meaning “great talent,” though Dojun privately thought of it as “the thing I got right”—weighed almost nothing. A few kilograms of possibility, wrapped in a hospital blanket, warm against his chest.
In sixty-eight years of memory, across two lifetimes of achievement and failure, Dojun had held many things he considered important: diplomas, trophies, contracts, patents, the keys to offices and the hands of the people he loved.
Nothing had ever weighed this much while being this light.
“I’m going to be a good father,” he said to the baby, who was asleep and unimpressed. “Better than the one I didn’t have. Better than the one I would have been.”
“You already are,” Hana said.
His mother arrived at 7:15—exactly forty minutes, as promised, though she had clearly run from the subway station because she was out of breath and her market apron was still on.
“Where is he?” she demanded, pushing past a startled nurse.
“Mom, you can’t just—”
But she was already at the bedside, already looking at the baby in Dojun’s arms, already crying in the particular way that Korean grandmothers cry when they meet a grandchild for the first time—with their whole bodies, without reservation, without the slightest pretense of composure.
“Give him to me,” she said, and her voice cracked on every word.
Dojun placed Hajun in his mother’s arms. She held him the way she held everything precious—firmly, carefully, with the practiced confidence of hands that had handled fragile things for thirty years.
“Park Hajun,” she whispered to the baby. “I’m your halmeoni. I make the best japchae in Seoul, and one day I’ll teach you how.” She looked up at Dojun, and her face—the face that had been the first thing he saw in both of his lives, the face that had fed him and scolded him and believed in him through every impossible transformation—was radiant.
“You did well, Dojun-ah,” she said. “Both of you did well.”
“He has Hana’s nose,” Dojun said.
“He has my chin. The Park chin. Strong.” She traced the baby’s jawline with her finger. “This child is going to be stubborn. I can already tell.”
“He’s a Park. Of course he’s going to be stubborn.”
“And an Lee. Hana’s family is stubborn too. This child has no chance of being agreeable.” She said it with absolute delight.
The visitors came in waves.
Minjae arrived with flowers and a stuffed penguin that was larger than the baby. “I didn’t know what to bring. The penguin seemed right. Penguins are loyal parents. It’s a metaphor.”
Seokho arrived with Keiko, carrying a precisely wrapped gift that turned out to be a children’s book on algorithms. “Start early,” he said. “Sorting algorithms are excellent bedtime stories. Bubble sort is soothing. Quicksort is exciting.”
“He’s six hours old, Seokho.”
“Neural plasticity peaks in the first year. Early exposure to computational thinking—”
“He’s six hours old.”
“Fine. Start with bubble sort.”
Kim Taesik arrived the next morning, carrying a coffee—for himself, not for Dojun—and a card that he had written by hand. The card said: To Park Hajun: Welcome to the world. Your father is the most unusual person I have ever met. You will have an interesting life. — Professor Kim Taesik, Seoul National University
“That’s the most emotionally restrained birth card I’ve ever seen,” Hana said.
“Emotional restraint is my brand,” Kim said. “Congratulations to you both. The child is healthy?”
“Healthy, stubborn, and—according to my mother—already showing signs of the Park chin.”
“The Park chin is a reliable genetic marker. Your mother has excellent observational skills.” He sipped his coffee. “Park. A word in private?”
They stepped into the hallway. Kim’s expression shifted from warm to serious—the shift that Dojun had learned to recognize as the prelude to important advice.
“You’re a father now,” Kim said. “That changes the calculation.”
“I know.”
“Do you? Because in your… previous experience… you were not a father. You have no template for this. No future knowledge to draw on. For the first time since 2006, you’re encountering something completely new.”
He was right. In sixty-eight years of combined memory, Dojun had never been a parent. Prometheus Labs Dojun had never married, never had children, never held a baby in a hospital room and felt the terrifying weight of being responsible for a life that was entirely dependent on him.
“I’m scared,” Dojun said.
“Good. Scared parents pay attention. Confident parents make assumptions.” Kim finished his coffee. “One piece of advice, from a man who has mentored students for twenty-five years but has no children of his own.”
“I’m listening.”
“Don’t build the child. Raise the child. Building is what you do with products—you design, optimize, iterate. Raising is what you do with people—you provide the conditions for growth and then get out of the way.” He set his empty cup on a window ledge. “Your mother didn’t build you. She raised you. There’s a reason you visit her every Saturday, and it’s not because she optimized your childhood.”
“She raised me.”
“She raised you. With japchae and stubbornness and the kind of love that doesn’t need to be engineered because it’s already whole.” He clapped Dojun on the shoulder. “Do that. Be that. The coding can wait. The baby can’t.”
The first night home was chaos.
Not bad chaos—the particular chaos of two people who had managed a hundred employees, four international offices, and a million-user product, discovering that none of those skills prepared them for a three-kilogram human who needed feeding every two hours and communicated exclusively through crying.
“He’s hungry,” Hana said at 2 AM, interpreting the cries with the pattern-recognition skills of a designer who had been trained to read user behavior.
“He’s always hungry. He’s been alive for three days and his primary activity is consumption.”
“He’s a startup. Startups consume resources. It’s normal.”
“Did you just compare our son to a startup?”
“High growth potential, zero revenue, extremely demanding of attention. The parallels are exact.” She fed the baby. He fed on the bottle they had prepared. The crying stopped. Silence filled the apartment—the particular 2 AM silence of a household where the baby has finally stopped crying and nobody dares speak in case it starts again.
“I should take paternity leave,” Dojun said.
“You should take paternity leave.”
“How long?”
“As long as you need. The company has Minjae, Jiyoung, Taeyoung, Hyunwoo—a leadership team that runs the operation while we’re gone. That’s the whole point of building a team that doesn’t need its founders in the room.”
“I’ll take three months.”
“Three months.” She looked at him. “The CEO of a hundred-person company taking three months of paternity leave. That’s going to make news.”
“Good. It should make news. If we can’t live our own values, we don’t deserve to build products that organize other people’s lives.”
“Put that in the company blog.”
“I will.”
He did. The blog post—”Why I’m Taking Three Months Off: A CEO’s Case for Paternity Leave”—was published the following week. It went viral in Korean tech circles, was translated into English and Japanese, and was cited in three subsequent articles about work-life balance in the Asian startup ecosystem.
The response from Aria’s employees was immediate and overwhelmingly positive. Two other fathers in the company, who had been hesitant to take leave, submitted their requests the same day.
“Culture is set by what leaders do, not what they say,” Minjae texted Dojun. “You just set the culture for the next decade.”
Three months of paternity leave. Ninety days of 2 AM feedings, diaper changes, pediatrician visits, and the slow, bewildering education of a man who could build an AI-powered productivity platform but could not, for the life of him, figure out why the baby cried when the apartment was 23 degrees but stopped crying when it was 22.
“One degree,” he told Seokho during a phone call. “One degree of temperature makes the difference between screaming and sleeping. I’ve optimized server clusters with less sensitivity.”
“Babies are more complex systems than servers. More variables, fewer logs, and the error messages are entirely non-verbal.” A pause. “How are you?”
“Exhausted. Happy. Terrified. In that order.”
“The same three emotions you listed when you won the Innovation Showcase six years ago.”
“Parenthood is a startup. Same emotions, higher stakes.”
“And no exit strategy.”
“No exit strategy.”
Saturdays continued. Even during paternity leave—especially during paternity leave—Dojun brought Hajun to Namdaemun Market. The baby slept through the noise of the market, the smell of garlic and sesame, the shouting of vendors. Younghee held her grandson behind the counter while serving customers, demonstrating the particular Korean grandmother skill of conducting commerce while simultaneously cradling an infant.
“He sleeps through everything,” she said. “Like his father. Dojun slept through earthquakes as a baby. I used to check his pulse because the silence worried me.”
“I was a quiet baby?”
“You were a terrifying baby. Quiet babies are either very content or very planning something. I was never sure which.”
“And Hajun?”
“Hajun is content. I can tell by his hands—they’re relaxed. Content babies have relaxed hands. Anxious babies make fists.” She shifted the baby to her other arm with practiced ease. “He has the Park chin and the Lee eyes. A good combination. Strong and perceptive.”
“You’re assessing his personality based on his chin and his hands.”
“I’ve assessed ten thousand customers based on how they hold their chopsticks. A chin and hands are more data than I usually get.”
She wasn’t wrong. The market had taught her a kind of human analytics that no algorithm could replicate—the reading of micro-expressions, posture, grip pressure, eye contact. Decades of face-to-face commerce had made her a expert in the most ancient form of data science: the observation of people.
Dojun watched his mother hold his son and felt the particular vertigo of generational time—a woman who sold banchan from a market stall, a man who built AI-powered productivity software, and a baby who would grow up in a world that neither of them could fully imagine.
Three generations, connected by a stall in Namdaemun Market, by japchae and kimchi and the simple, stubborn act of showing up.
The baby slept. The market hummed. And the man who had lived twice held his son and knew, with a certainty that transcended timelines, that this—this small, warm, sleeping person—was the best code he would ever help write.
