Perfected Abnormality - Windbreaker

Chapter 1.

"That was ass." A single comment left the mouth of a young man as he stared at his phone intently. On the screen was a manhwa panel depicting a beautifully drawn red-haired man. His mouth twitched in annoyance, irritated by how frustrating the sequence of events had become. It was predictable, yet it still pissed him off the moment it was released.

"Retard. How shallow does he think? As expected, anyone other than Minu is dumb in this crew," he spat, the irritation getting to his head.

The man glaring at his screen was named Kurt—a guy who developed a passion for biking after reading a single manhwa. The moment he discovered this piece of work, it consumed all his attention. He quit playing video games, stopped drinking, gave up smoking, and even distanced himself from his friends. He was completely enchanted by the fiction he had read.

He became so obsessed with the story that he went out and bought a bike for himself, determined to ride just like the characters. But reality hit him hard—it made him realize he had no talent whatsoever for cycling. Still, that was only a minor setback. For him, biking wasn't about skill or image; it was about fun. He enjoyed riding around town, feeling the wind brush against his body, and noticing the little details in his surroundings.

He was hooked. That's why he supported this manhwa with all his heart, never missing a single release. The pacing might be garbage at times, but it wasn't enough to break his fascination with the story. As he stared at the screen, he wondered if he should buy another outfit. Every piece of clothing in this series looked amazing.

"Sounds like a good idea," he muttered, brushing away his irritation as he started pedaling his bike.

Destination? Thrift shop.

As he rode, he let go of the handlebars for a moment and reached for his phone, opening TikTok. Scrolling absentmindedly, he suddenly heard loud music blasting from somewhere.

"Is this meme still alive…?" he wondered.

The music grew louder—no, it was everywhere. Left, right, front, and back. It surrounded him completely.

Then, he recognized it. The unmistakable sound of a JBL speaker blaring at full volume.

'I want you to be mine again, baby, ayy~'

'I know my lifestyle is drivin' you crazy, ayy~'

'I cannot see myself without you—'

That was the last thing Kurt heard before his body was flung through the air.

A small truck had slammed into him.

'Damn you… JBL!'

That was his final thought before his consciousness faded into nothingness.

[Hm, what should I give this young man? His love for my favorite manhwa has certainly piqued my interest.]

An overwhelming voice echoed through the void, yet no figure could be seen. It was as if the sound existed purely for formality. In this realm of emptiness—where neither concepts nor materials held meaning—a voice was heard.

[This should be enough. Enjoy my gift, young man.]

And with that, the voice faded.

It was a short and simple phenomenon, yet the change it would bring was immense—enough to alter the very balance of causality.

"Fuck!"

Kurt jolted awake, gasping. His own voice startled him—it was raspy, weaker, and… immature? Confused, he quickly tried to piece together what had just happened. The last thing he remembered was—

SLAP!

A sharp sting spread across his cheek, shocking him to full alertness. He turned toward the source, only for his eyes to widen at the scene before him.

Four people stood nearby. Three of them had expressions of pure shock, while one was absolutely seething with rage.

It didn't take long for him to realize—he was definitely fucked.

"You brat! Who taught you to curse like that?!"

The furious woman shouted straight into his face. Kurt stood there, completely dumbfounded. What the hell is happening?

SLAP!

Another hit.

This time, he couldn't take it. "AGGGHHHHHHHHHHHHHHHH! CRAZY HAG!" he screamed at the top of his lungs.

As soon as the words left his mouth, the expressions of those around him grew even more astonished. The woman—his supposed mother—raised her hand again, but this time, a man held her back. He seemed torn between confusion and disbelief.

Their child, who had always been obedient and respectful, was suddenly acting completely out of character.

"Let go of me! I need to teach this brat a lesson! How dare he talk back to his mother like that?!" the woman roared, struggling against her husband's grip.

Meanwhile, Kurt's mind finally gave out.

When he regained consciousness, he was lying in bed. His face still stung. As he reached up to touch his swollen cheek, he muttered, "Fuuh… shit, that wasn't a dream."

His eyes drifted to the side, where two young kids sat, watching him with uncertainty.

His mind raced. That woman just now… or rather, his mother…

"Wait… that was Jay Jo's mom, wasn't it?"

A terrible realization dawned upon him, but before he could process it further, the two children continued staring at him, their expressions unreadable.

"Hyung… are you alright?"

The voice belonged to a kid Kurt instantly recognized—one of the main characters of the manhwa he had just been reading. Jay Jo.

Hyung?

The word lingered in his mind as he glanced down at his own body. He sighed, clicking his tongue before finally accepting the absurd situation he was in.

"Yeah, I'm fine," he muttered, standing up and stretching.

But something felt… off. His body didn't feel weak like a kid's. Instead, it was brimming with energy—far stronger than what he expected.

"Hyung, are you really okay? What happened earlier?" Jay asked again, his wary eyes fixed on Kurt. His brother had always been an obedient, well-mannered child—never once speaking back to their parents, let alone acting out like he had earlier.

It was no surprise that both Jay and their younger brother were now on edge around him.

Kurt sighed. "I said I'm fine. Go back to your own room."

Shooing them away, he began taking off his shirt, preparing to change. But before he could, their youngest brother suddenly screamed.

"AHHHHHHHHHH!"

Kurt blinked, confused. Jay was just as dumbfounded.

The two kids pointed at Kurt's body, their eyes wide with shock.

"…I'll be damned," Kurt muttered in awe as he finally took a proper look at himself.

His body was undeniably that of a young kid—but there was something wrong. Beneath his youthful frame, visible muscle definition was starting to emerge.

Curious, he pinched his arm. To his surprise, it wasn't just soft fat—there was actual, considerable muscle.

"Ahhhhh, MOM!!" Kay Jo screamed, his young mind unable to process what he was seeing.

Loud footsteps thundered down the hallway. Both Kurt and Jay flinched—an instinctive reaction to an incoming threat.

The door slammed open, revealing their enraged mother. "What is it this time?!" she snapped, their father trailing behind her.

But the moment their parents saw Kurt, their jaws dropped.

Especially their mother—who, as a doctor herself, knew this kind of change shouldn't be possible.

"H-Honey… what is this?" their father stammered.

Before he could get an answer, his wife had already rushed toward Kurt.

Kurt flinched as her hand shot out, aiming for his ear.

SWOOSH!

"…Hah?"

Everyone in the room—Kurt included—reacted with utter confusion.

Somehow, he had dodged her grab attempt by a hair's breadth.

Oh shit…

His mother's face turned a dangerous shade of red.

She reached out again—faster this time.

SWOOSH!

Dodged.

It wasn't on purpose. He hadn't even thought about moving. His body had simply reacted on its own.

"BRAT! Stop dodging and let me grab you!!"

His mother lunged again and again, but Kurt effortlessly evaded each attempt, his movements faster than her reaction time—almost inhuman.

"W-Wait, Mom! I swear I'm not doing this on purpose!" he tried to explain, but considering he was still dodging while saying that… it wasn't exactly convincing.

As their mother struggled to catch Kurt, the rest of the family simply stood there, watching in stunned amazement.

Jay, Kay, and their father were speechless.

Kurt's movements were unnatural. Almost creepy.

Yet at the same time… it was incredible.

"C-Come on, Kurt! Enough of this!" Their father finally snapped out of his daze and tried to intervene.

Meanwhile, Kurt was having a crisis of his own.

What the hell is going on?!

It was weird enough that he could dodge his mother with zero effort—but the fact that he could think clearly while doing so was even more bizarre.

A sudden movement in front of his face caught his attention.

A fly.

A terrible foreboding crept up his spine.

CLAP!

A loud noise echoed through the room.

Everyone froze.

Kurt slowly opened his hands… revealing the disintegrated remains of the fly inside.

His mother took a step back before dramatically losing consciousness.

"Honey!" Their father caught her just before she hit the ground.

Then he turned to Kurt, his expression serious.

"Kurt Jo! You're grounded for a whole month! Spend that time studying!"

With that, he carried his wife out of the room in a hurry.

Jay and Kay were left standing there, still too stunned to react.

"…Go away, brats," Kurt muttered, waving them off.

The two immediately bolted, leaving him alone.

Kurt stared at his hands, his lips twitching in disbelief.

"This reflex is insane," he murmured.

Just then, another fly buzzed past him.

His body moved on its own.

CLAP!

He hadn't even registered the motion. His consciousness simply couldn't keep up with his own speed.

Kurt grinned.

"Now this is what I call awesome."

Still… he had entered this world.

"How the hell did that happen? Was the JBL speaker involved? That'd be crazy…"

He had countless questions.

But for now, all he could do was find answers… and maybe, just maybe, enjoy his time here.

Here's your cleaned-up version while keeping the style simple and natural:

The next few days were spent with their mother investigating Kurt's condition. She experimented with everything and eventually concluded that Kurt was abnormal.

His reflexes were insane—so fast that, theoretically, even if someone pointed a gun at him, he'd be able to dodge it. Of course, that was just her assumption. But considering what she had seen so far, it wasn't impossible.

His strength was equally ridiculous. Despite his muscles still being underdeveloped, he could generate incredible power. The best proof? He shattered a 100kg handgrip strength tester as if it were made of cheap plastic. His mother stopped the tests there, fearing an accident might happen.

Now, the last thing left to test was his intellect.

That test was scheduled for today.

She carefully prepared a stack of exams, ensuring the questions were challenging but still within the capabilities of a middle schooler. Since this was her son, she had high expectations.

Handing him a test paper with 100 questions—mostly math and science—she instructed, "Answer these. You have one hour."

Five minutes later...

Kurt handed back the test. His mother raised an eyebrow. "Are you giving up?" she asked, irritation creeping into her voice.

Kurt's lips twitched as he shook his head. "No, I'm done."

She snatched the paper from his hand and started grading.

Silence.

Her eyes widened in disbelief. Every single answer was correct. Not only that, but he had also corrected errors in the questions themselves.

'How...?' she wondered but quickly shook the thought away. She had already been shocked enough over the past few days—nothing should surprise her anymore.

But she wasn't done testing him yet.

She handed him a Rubik's cube. "Solve this."

Kurt just raised an eyebrow, took the cube, and solved it in seconds without even trying.

Even he was surprised at how absurdly fast his mind was working. Without much thought, he tossed the cube back to his mother.

Now, her pride was on the line.

She pulled out a chessboard and took a seat across from him. "Play with me."

Kurt sighed but went along with it, setting up the pieces.

Eight games later...

His mother clenched the king piece in frustration. She had lost eight consecutive times—no, she couldn't even call it "losing." From the way Kurt looked utterly bored, it was clear that he knew the outcome the second she made her first move.

Still, she forced herself to remain calm. There were more tests to run.

She raised the difficulty and gave him high school-level questions. He aced them just as quickly.

At this point, her lips curled into a wide smile.

Her mind was already racing with possibilities—competitions, scholarships, achievements. Their family could rise to the top with his abilities.

"Son, let's continue," she said eagerly, eyes gleaming.

Meanwhile, Kurt shivered.

He could already tell—this was going to be a long, long day.

And just like that, his mother finally accepted it.

Her son was, without a doubt, the peak of humanity.
