The days leading up to Sunday felt like a choreographed dance between two people who had finally found the right rhythm.
The "Oppa" barrier had been breached, and with it, the stiff formality of CEO and Teacher had begun to dissolve into something far more intimate.
Every morning at 6:00 AM, the gym of their luxury complex became their private sanctuary.
The rhythmic thud of the treadmill and the metallic clank of weight plates were the soundtrack to their burgeoning romance.
Jin-woo no longer exercised separately and began to stay near Eun-soo in the gym; he preferred the sound of Eun-soo's laugh as she teased him about his "intense" lifting face.
They had moved past small talk.
Between sets of squats and intervals on the rowing machine, they shared fragments of their lives.
Eun-soo learned that Jin-woo's stoic exterior was a shield he'd built while navigating the shark-infested waters of financial district.
Jin-woo learned that Eun-soo's warmth wasn't just a professional trait—it was a core part of her soul, forged from a childhood spent in a house full of music and chaotic family dinners.
By Wednesday, the phone calls started.
They began by discussing Hajun's schedule, but they invariably stretched into hour-long conversations that lasted well past midnight.
"Is he asleep?" Eun-soo would whisper into the phone, her voice hushed so as not to wake Hajun, while she curled up on her sofa with a book she hadn't turned a page of in thirty minutes.
"Out cold," Jin-woo would reply. "I think he'll sleep until the sun comes up; he spent the afternoon playing soccer."
"Also, I wanted to ask you... do you really think I should wear that blue tie for the board meeting tomorrow, or was that just a polite suggestion?"
"It wasn't polite, Jin-woo. It matches your eyes. It's a power move."
"A power move, huh? I'll hold you to that."
The silent acknowledgment was there: they were no longer just neighbors. They were a "we."
Eun-soo began to prepare food for Jin-woo and Hajun more often—not just breakfast, but sometimes dinner as well.
On Thursday night, the neon lights of Myeongdong flickered to life as the sun dipped behind the Namsan Seoul Tower, transforming the bustling district into a glittering labyrinth of steam, scents, and laughter.
Thursday night had arrived, and with it, a sense of belonging that made the crowded streets feel like their own private playground.
Jin-woo parked the SUV a few blocks away, and as they stepped onto the main pedestrian strip, he didn't hesitate.
He reached down, his large hand finding Eun-soo's and interlacing their fingers.
It was a firm, public declaration that sent a fresh jolt of electricity through her.
Between them, Hajun skipped along, his small hand gripping Jin-woo's other side, his eyes wide at the sheer spectacle of the night market.
The air was thick with the savory aroma of grilling meat and the sweet scent of caramelized sugar.
Their first stop was a brightly lit stall where a mountain of Tteokbokki simmered in a deep red, glossy sauce.
"Oppa, you have to try this one," Eun-soo said, picking up a toothpick.
She blew on a chewy rice cake before holding it up to his mouth.
Jin-woo leaned in, eyes locked on hers, and took the bite.
"Spicy," he admitted, his brow furrowing in that way she'd grown to love, "but the sweetness hits right at the end. Here, try the Eomuk."
He dipped a skewer of folded fish cake into the steaming broth and offered it to her.
They stood there for a moment, tucked into a corner of the stall, oblivious to the sea of tourists and shoppers flowing past them.
Every few seconds, Hajun would chime in, "My turn! My turn!" as he happily munched on a Gyeran-ppang.
The warm, fluffy egg bread left a trail of crumbs on his chin.
As they moved deeper into the market, the energy became more intense.
They navigated the crowd like a single unit.
When a group of hurried shoppers pushed past, Jin-woo instinctively pulled Eun-soo closer, his arm sliding around her waist to shield her.
They found a small, makeshift table behind a stall selling Dak-kkochi.
It was just a simple plastic surface with two tiny stools, but to them, it felt like a VIP table at a five-star restaurant.
They laid out their spoils—crispy Twigim, a tray of steaming Mandu, and a golden Korean Corndog coated in sugar and cubes of potato.
Eun-soo took a bite of a kimchi dumpling and immediately hummed in delight. "This is the best I've had in years."
Jin-woo leaned over, using his own chopsticks to steal a piece of her fried sweet potato.
"You're right. Everything tastes better when I'm not eating it alone in a boardroom."
As they ate, the conversation slowed into a comfortable, rhythmic hum.
Hajun was busy dipping his Gimbap into the leftover Tteokbokki sauce, his face a mask of pure concentration.
Eun-soo felt a wave of peaceful exhaustion wash over her.
She shifted on her stool, leaning her head naturally onto Jin-woo's shoulder.
He didn't miss a beat, tilting his head down so his temple rested against the top of her head.
"You okay?" he whispered, his voice vibrating through her.
"Perfect," she replied, closing her eyes for a second. "I didn't know Myeongdong could feel this... quiet."
"It's not the place, Eun-soo," Jin-woo said softly, his hand finding hers under the table and squeezing. "It's the company."
Before heading back to the car, they made one final stop at a stall where the vendor was expertly pressing Hotteok.
The smell of cinnamon and melting brown sugar was irresistible.
"One for the road?" Jin-woo asked.
They shared a single, piping-hot pancake, tearing off pieces for Hajun, who was now clutching a Bungeoppang filled with custard in his other hand.
The warm syrup threatened to drip, and Eun-soo quickly reached out with a napkin to wipe Jin-woo's thumb.
"You're a mess, CEO-nim," she teased, her eyes sparkling under the streetlights.
"I think I prefer this version of myself," he countered, looking down at his sugar-dusted shirt and then at the woman who had caused it.
As they walked back toward the car, the air was filled with the soft sounds of K-pop on the radio and Hajun's quiet breathing as he drifted off to sleep.
His belly was full of street food and his heart was full of the new "family" dynamic.
Jin-woo kept one hand on the steering wheel and the other firmly clasped with Eun-soo's over the center console.
The relationship wasn't just "almost" confirmed anymore; in the neon glow of the Seoul night, it felt like the most certain thing in the world.
Sunday was only two days away, but for the first time in his life, Jin-woo wasn't rushing toward the future.
He was exactly where he wanted to be.
The next day they went to their destinations as usual.
Nothing had changed externally, but the people in their lives had changed, which changed the way they looked at life.
On Friday evening, the black SUV pulled into the kindergarten drop-off lane exactly as the final bell rang.
Jin-woo didn't wait in the car this time.
He stood by the gate, leaning against the hood, looking every bit the high-powered executive, yet his eyes were focused solely on the glass doors.
When Hajun spotted him, the boy didn't just walk; he launched himself like a projectile.
"Uncle! You're early!"
Jin-woo caught him with practiced ease, swinging him up. "I promised, didn't I?"
Eun-soo followed close behind, smoothing her skirt with a soft smile playing on her lips.
The way Jin-woo's gaze softened when it landed on her was enough to make the other teachers whisper behind their clipboards.
"Rough day?" Jin-woo asked, reaching out to take Eun-soo's heavy tote bag before she could even protest.
"Just long," she admitted. "But seeing you... seeing both of you makes it better."
The drive home was a domestic blur of comfort.
They stopped briefly at Eun-soo's floor first.
As the elevator doors opened, Jin-woo handed her the bag back and said goodbye.
Since today was Friday and the weekend was free, Jin-woo decided to spend some late-night time with Hajun.
"Hajun, what do you think of your favorite math documentaries and extra-large popcorn tonight?"
Hajun cheered, and as Eun-soo stepped out onto her floor, she watched the doors close on two of the most important people in her world.
It felt like home.
