Chapter 24: One Year
March 7th, 2007. Exactly one year since Park Dojun had opened his eyes in Professor Kim Taesik’s lecture hall and discovered that he was twenty years old, alive, and terrified.
He marked the anniversary the same way he had spent most mornings that year: running. Five kilometers around the campus track, breath steaming in the late-winter air, sneakers crunching on frost-dusted pavement. The cherry trees along the main walkway were still bare—the blossoms wouldn’t come for another three weeks—but their branches had a swollen quality that promised spring.
One year. He had been alive—this version of alive—for exactly 365 days.
He finished his run and sat on the bench near the engineering building, the same bench where he had sat under a ginkgo tree in September and asked himself if he was a good person. The ginkgo was bare now, but he could see the tiny green nubs of new leaves forming along its branches.
He pulled out a notebook and wrote:
Year One inventory:
People: Mom (alive, healthy, using a laptop to track banchan sales). Hana (co-founder, designer, the person who makes everything make sense). Seokho (collaborator, rival, friend — in that order, or maybe the reverse). Minjae (co-founder, the reliable center of everything). Kim Taesik (mentor, shield, the man who chose to believe without understanding). Hyunwoo (first hire, the future of Bridge’s engineering). Yuri (B+ in math, considering engineering for high school). Choi Eunji (investor, advisor, the bet that held).
Products: Bridge (campus beta — 487 DAU, 92% accuracy, learning module live). Bridge Market Edition (two users — Mom and Mrs. Kang’s socks stall. Small but real).
Papers: ISCA 2007 (accepted, presenting in June). SIGCOMM 2007 (in progress with Seokho, submitting April). Pathfinding paper (published, cited twice).
Money: 43 million won remaining from seed. Monthly burn: 3.2 million. Runway: 13 months.
What I didn’t expect: That the hardest part wouldn’t be the code or the competitions or the papers. The hardest part was learning to say “I don’t know” to people I could answer in my sleep. Learning to let things be imperfect. Learning that the version of Bridge that runs with bugs and patches and a wobbly chair is more valuable than the perfect version that exists only in my head.
What I got wrong: I thought I needed to recreate Prometheus Labs. I don’t. I need to build something that’s mine — that belongs to this life, not the last one. Bridge is smaller, slower, humbler. It’s also realer.
What I got right: The people. Every one of them. The web holds because I chose the right people and gave them reasons to stay.
He closed the notebook. The campus was waking up around him—students heading to 9 AM classes, professors crossing the quad with coffee cups, a maintenance worker sweeping yesterday’s leaves. The ordinary machinery of a university day, cycling forward into spring.
His phone buzzed. Hana:
Happy anniversary.
He stared at the text. She knows. Not the impossible truth—but the date. She had noticed, somehow, that March 7th mattered to him. He had never told her. She had simply observed.
Anniversary of what? he typed back, testing.
Of whatever happened to you last March 7th that made you start showing up for the people around you. I don’t know what it was. But something changed on that day, and I’m glad it did.
He sat on the bench for a long time, holding the phone, reading and rereading her message.
I’m glad too, he typed.
Jjigae tonight? My treat. Anniversary tradition starts now.
Deal.
The spring semester brought Bridge’s expansion to Korea University and Yonsei—two new campuses, 1,200 new users in the first week alone, and a cascade of infrastructure challenges that kept Hyunwoo and Minjae working fourteen-hour days for a month.
“The sync layer is holding,” Hyunwoo reported during a March standup, looking simultaneously exhausted and triumphant. “The rewrite I did in December is handling the load. Peak concurrent users: 1,847. No crashes. One timeout event, caused by a KU student who somehow uploaded 3,000 emails in one batch.”
“Three thousand emails?” Hana said. “Who has three thousand unread emails?”
“Apparently a fourth-year law student who hasn’t checked his inbox since 2005. Bridge tried to organize them and briefly considered requesting a raise.”
The multi-campus expansion also brought Bridge its first press coverage. A student journalist at Korea University wrote a feature: “Bridge: The App That Organizes Your Chaos.” The article went viral on campus forums, generating 400 waitlist signups in 48 hours.
“App,” Hana noted. “She called it an app. It’s not an app—it’s a desktop application. But the word ‘app’ is starting to mean something different.”
“It will mean something very different very soon,” Dojun said.
“There you go again. Speaking like a prophet.” She nudged him. “When is ‘soon’?”
“June,” he said, and immediately regretted it.
“What happens in June? Besides your ISCA presentation?”
“I have a feeling that June is going to be a big month for technology.”
“A feeling.” She studied him. “Your feelings are suspiciously specific for someone who claims not to see the future.”
“I claim no such thing. I just don’t explain my methodology.”
“One day, Park Dojun.”
“One day.”
April brought the SIGCOMM submission and a surprise visitor to the Bridge office.
Jang Seokho arrived unannounced on a Tuesday afternoon, carrying his KAIST backpack and a USB drive containing the final draft of their collaboration paper.
“I could have emailed this,” he said, handing the USB to Dojun. “But I wanted to see your office.”
“It’s twelve square meters.”
“It’s bigger than my KAIST lab desk.” He surveyed the room—the whiteboard covered in Hana’s flowcharts, Minjae’s dashboard projection on the wall, Hyunwoo’s dual-monitor setup in the corner, the three non-wobbly chairs they had finally purchased. “You’ve built something here.”
“A closet with WiFi.”
“A company. With a product, users, and revenue potential.” He sat down in the guest chair—still the original wobbly one, kept as a founding artifact. “I came because I have something to tell you, and I wanted to say it in person.”
“Good news or bad?”
“Unusual news.” He paused—a rare display of hesitation from someone who usually spoke with the precision of a compiler. “I’ve been offered a position at Samsung’s semiconductor division. A research role in their new mobile processor team. Full-time, starting after graduation.”
“Samsung. That’s a strong offer.”
“It’s the strongest offer in the Korean industry. Salary, benefits, research autonomy—everything I would want from a corporate position.” He looked at Dojun. “I’m turning it down.”
“Turning it down? Why?”
“Because I want to build something. Not for Samsung. Not for KAIST. For myself.” He leaned forward. “I’ve been watching you build Bridge for a year. Watching you go from a group project to a funded company with real users. And I realized something: the most interesting work in technology isn’t going to happen inside corporations. It’s going to happen in places like this.” He gestured at the twelve-square-meter office. “Small teams. Real problems. No bureaucracy.”
“You want to start a company.”
“I want to start a company.” He said it with the quiet certainty of someone who had made a decision and was not looking for permission. “Not a competitor to Bridge. Something complementary. I’m thinking about infrastructure—the backbone systems that companies like yours will need to scale. Cloud computing, distributed systems, the kind of plumbing that nobody sees but everyone depends on.”
Cloud computing. In April 2007, Amazon Web Services had been operating for less than a year. The idea of building a cloud infrastructure company in Korea was prescient—almost impossibly so. But Seokho had always been prescient. In the original timeline, he had built exactly this kind of company: Nova Tech, a cloud infrastructure provider that had grown to rival AWS in the Asian market.
“When?” Dojun asked.
“After graduation. December. I’ll spend the summer preparing—business plan, technical architecture, seed funding.” He met Dojun’s eyes. “I’m not asking for your involvement. I’m asking for your advice. You’ve done this. You know the path.”
“I’ve done a very small version of this.”
“You’ve done the hardest version—the first time. Everything after that is iteration.” He stood. “I need to catch the 5:20 train. But I wanted you to know. You’re the only person, besides my mother, who I told before making the decision.”
“I’m honored.”
“Don’t be honored. Be available. I’ll need someone to argue with about architecture decisions, and you’re the only person who argues back with data.”
They shook hands at the office door. Seokho’s grip was firm—the grip of someone who had just decided to jump and was already calculating the trajectory.
“Seokho,” Dojun said. “For what it’s worth—you’re making the right decision. The infrastructure space is about to explode. And you’re exactly the person to build in it.”
“How do you know the infrastructure space is about to explode?”
“I read a lot.”
“The catchphrase.” Seokho shook his head. “One day I’m going to find out what you actually read, and it’s going to explain everything or nothing.” He walked down the hallway, waved without turning, and disappeared into the stairwell.
Dojun stood in the office doorway and watched him go. In the original timeline, Seokho had started Nova Tech in 2010—three years from now—after spending those years at Samsung gaining industry experience. Here, he was starting three years earlier, driven not by Samsung burnout but by inspiration from watching Bridge grow.
The butterfly effect. Every change rippled outward, creating new patterns, new possibilities, new paths that the original timeline had never imagined.
Seokho and Dojun. Not competitors this time. Collaborators. Building parallel companies in complementary spaces—one focused on the product layer, the other on the infrastructure beneath it.
In thirty years, this conversation might be remembered as the moment Korean tech’s two greatest founders decided, in a twelve-square-meter office, to build an ecosystem instead of an empire.
Or it might be forgotten entirely, buried under the weight of everything that came after.
Either way, the decision was made. The paths were diverging from the original timeline in ways that Dojun could no longer predict or control.
And for the first time, that felt right.
May. The SIGCOMM paper was submitted. The ISCA presentation was rehearsed twelve times—six with Kim Taesik drilling Q&A, six with Seokho attacking every weak point with the merciless precision of a crash test engineer.
“Your slide on power consumption is too detailed,” Kim said during rehearsal. “The audience will lose you at slide eight. Simplify.”
“Your answer to the classifier question is too smooth,” Seokho said during his rehearsal. “Real twenty-year-olds hesitate. Add a pause. A ‘hmm.’ Look at the ceiling like you’re thinking. Even if you already know the answer.”
“You’re coaching me to perform ignorance.”
“I’m coaching you to perform humanity. Which, for you, requires performance.” The thin smile. “You’ll do fine. You always do.”
Bridge’s user count crossed 3,000. The learning module’s accuracy reached 93%. Choi Eunji’s monthly report to her partners at Hankook Ventures included the phrase “fastest-growing student-founded software company in Korea,” a designation that was technically accurate and practically terrifying.
Hana designed Bridge’s mobile interface mockups—not for a product that existed yet, but for a product that would exist soon, on devices that hadn’t been announced yet.
“When smartphones become mainstream,” she said, showing Dojun the mockups during a Thursday dinner, “Bridge needs to be ready. The task-centric interface translates perfectly to a small screen. Each task card becomes a widget. The context toggles become gestures. It’s actually better on mobile than on desktop.”
“You’re designing for a device that doesn’t exist.”
“It will exist. I have a feeling.” She smiled. “I learned that phrase from you.”
June approached. San Diego. ISCA. The world stage.
And somewhere in Cupertino, California, a man named Steve Jobs was rehearsing a presentation that would change the definition of the word “phone” and, with it, the future of technology, of Bridge, and of every person Dojun cared about.
The iPhone was coming. And this time, Dojun would be ready.
Not because he knew the future. But because the people he had built his life around—Hana, Seokho, Minjae, Kim Taesik, his mother—had given him something that future knowledge alone could never provide.
A present worth fighting for.
