The morning sun rose slowly over the city, its light spreading across streets still damp from the previous night's rain.
Whatever had happened the night before had already begun to fade. The bodies were gone, the debris cleared, and even the blood had been washed away. To anyone passing by, it was just another ordinary morning.
But not everything could be erased.
Han Dae-Sung stood by the rear window, his gaze steady as he looked outside. His posture was relaxed, hands resting behind his back, but his eyes missed nothing. The dented metal of a dumpster, a shallow crack in the wall, and the awkward disturbance in the air, small details that most people would overlook but he said nothing, simply taking it all in before turning away as if it held no significance.
Inside the shop, the atmosphere was entirely different. The scent of fresh bread and coffee filled the air, and the quiet hum of appliances blended into the background. Tae-Hyuk moved between the shelves, adjusting items with his usual calm precision. There was no sign of fatigue in his movements, no trace of what had taken place only hours ago.
On the floor near the counter, Min-Jun lay sprawled out, one arm thrown over his face as he groaned softly. "Why do I have to wake up this early…" he muttered. "This is torture."
"Get up, Min-Jun," Tae-Hyuk said without looking at him. His voice was calm, but there was no room for argument. "You were the one who wanted to learn."
Min-Jun let out a long sigh and slowly dragged himself upright. "Can't I skip just one day? My whole body hurts."
"No."
The answer came instantly.
Min-Jun stared at him for a moment before muttering under his breath, "This is abuse."
From the back of the shop, Seo-Yeon stepped out carrying a tray of sandwiches and drinks. "If this is abuse, then you're the weakest victim I've ever seen," she said with a small smile.
Min-Jun shot her an annoyed look. "You're not the one suffering."
"At least you're improving," she replied lightly.
"That's debatable."
Tae-Hyuk allowed the conversation to pass without interruption before his gaze shifted slightly. "Hyun-Jae."
The boy, who had been standing quietly near the counter, straightened immediately. "Yes."
"Outside."
That was all he needed to hear.
Hyun-Jae moved quickly, already focused. The alley behind the shop had become familiar to him, no longer just a narrow passage but a place where every mistake was exposed. He stepped into position, exhaling slowly as he tried to steady himself.
"Begin," Tae-Hyuk said.
Hyun-Jae moved at once—punch, step, turn, kick. His movements were faster than before, more controlled, but still rough around the edges.
"Again."
He repeated it.
"Your balance."
Hyun-Jae adjusted.
"Your breathing."
He corrected again, this time more carefully.
Tae-Hyuk watched without emotion. "Do not separate your movement from your Qi. If you treat it as something external, you will never control it properly."
Hyun-Jae clenched his jaw slightly and tried again. This time, his movements smoothed out, not perfect, but closer.
"Again."
The training continued like that, repetition after repetition, each attempt pushing him slightly further. Sweat gathered on his forehead, running down his face, but he didn't stop. Tae-Hyuk stepped in occasionally, adjusting his stance, correcting the angle of his arm, making small changes that carried weight far beyond their simplicity.
Inside, Seo-Yeon stood near the doorway, watching quietly. Her gaze lingered on Tae-Hyuk, following the way he moved and the calm authority in his presence. There was something different about him now, something she couldn't fully explain.
Her eyes drifted to his hand.
There was a faint streak of dried blood along his knuckles.
"Tae-Hyuk…" she called softly.
He turned his head slightly toward her.
"You've… changed," she said, hesitating slightly.
He didn't answer immediately.
"I don't mean that in a bad way," she added. "Just… something feels different."
Tae-Hyuk looked at her for a moment before speaking. "Care is a luxury. Survival is a necessity."
Seo-Yeon frowned faintly. "That's not what I meant. I meant… with us."
There was a brief pause.
"Us?" he asked quietly.
"Yes.. no.. not us. I mean.. with my brother and dad" Seo-Yeon stammered.
"Well... you can say that."
It wasn't much, but it was enough to ease the tension in her expression.
Outside, Hyun-Jae stumbled, his footing slipping just slightly before he caught himself.
"Stop," Tae-Hyuk said.
The boy froze, breathing heavily.
"You are forcing it," Tae-Hyuk continued. "Qi does not respond well to force. Control it. Don't chase it."
"I can't even feel the Qi." Hyun-Jae protested.
"That is because you are thinking too much," Tae-Hyuk replied. "Again."
Min-Jun eventually dragged himself outside, watching for a moment before dropping down with a tired sigh. "How do you keep doing that over and over?" he asked.
"Because I want to get stronger," Hyun-Jae replied without stopping.
Min-Jun snorted. "I want to sleep."
"Then stay weak."
Min-Jun frowned at that. After a moment, he clicked his tongue and stood up. "Fine, I'll show you."
His movements were rough and inconsistent, lacking the control Hyun-Jae was beginning to develop, but he tried. That alone was enough for now.
Tae-Hyuk watched both of them in silence, saying nothing for a while, letting them struggle through it.
Time passed slowly, the rhythm of training continuing without interruption. The sun rose higher, then gradually began to dip again. Eventually, Tae-Hyuk raised his hand.
"Enough."
Hyun-Jae stopped immediately, breathing heavily. Min-Jun dropped to the ground again without hesitation.
"I'm dead," he muttered.
"You're alive," Tae-Hyuk replied calmly. "Which means you can improve."
Seo-Yeon stepped forward and handed Tae-Hyuk a bottle of water. Their fingers brushed briefly as he took it, a small moment neither of them commented on.
"Rest," he said. "We continue tomorrow, don't be late Hyun-Jae."
The two boys didn't argue.
Inside the shop, things returned to normal. Customers came and went, unaware of anything unusual. The quiet routine continued as if nothing had changed.
But in the back office, Han Dae-Sung sat alone, the door closed behind him. His eyes rested on nothing in particular as his thoughts returned to the alley, to the traces left behind.
"…What could've happened?" he murmured.
After a moment, he leaned back slightly, saying nothing more.
Outside, the city carried on, unaware of the quiet shift that had taken place. But beneath the surface, something had already begun to change. Not suddenly, not dramatically, but enough to set things in motion.
And in the middle of it all, Tae-Hyuk remained exactly where he needed to be, watching, teaching, and waiting.
The ripples had started.
It was only a matter of time before they spread.
