The door slammed so hard the walls shook.
Kang-Dae stumbled backward into the pouring rain, shirt half-open, pants barely zipped, his face burning with humiliation. Behind the closed door of Mi-Cha's luxury apartment, her laughter mixed with the deep chuckles of Park Ji-Hoon.
"Get lost, you pathetic loser!" Mi-Cha's voice pierced through the wood like a knife. "Two years! Two fucking years I wasted on a guy whose dick is smaller than my lipstick tube! I never felt anything, Kang-Dae! Nothing! Every time you finished in thirty seconds I wanted to scream!"
Ji-Hoon's loud laugh followed. "Bro, seriously? That's what you call a cock? No wonder she's been coming to me every night. Go home and cry, tiny. Maybe jerk off with two fingers since that's all you need."
Kang-Dae stood frozen under the heavy rain, water streaming down his face, mixing with the tears he could no longer hold back. His hands shook as he tried to button his shirt. The cold night air bit into his skinny, average body, reminding him once again how small and worthless he was.
He turned and walked away, shoulders slumped, head down. His phone buzzed repeatedly in his pocket. With trembling fingers he pulled it out.
Group chat notifications flooded the screen.
Ji-Hoon had already posted:
[Just kicked out the campus shrimp 😂 His dick is so small Mi-Cha says she felt nothing for two years. Anyone want to see the video?]
Dozens of laughing emojis. Replies from their so-called friends:
"Hahahaha poor guy"
"Tiny dick energy maxed out"
"Mi-Cha deserves better, not that disappointment"
Kang-Dae's vision blurred. He shoved the phone back into his pocket and kept walking through the rain until he reached his small, cheap one-room apartment on the edge of the city.
For the next thirty days, he barely left his room.
He stopped going to university. Stopped eating properly. Stopped showering most days. The same clothes from that night lay crumpled on the floor, still carrying the faint smell of rain and defeat. He spent hours staring at the ceiling, replaying Mi-Cha's cruel words and Ji-Hoon's mocking laughter.
Every night the group chat notifications grew worse. New memes. New insults. New photos of Mi-Cha and Ji-Hoon looking happy together. Someone even started a poll: "How small is Kang-Dae's dick? Vote now!"
On the thirty-first night, Kang-Dae sat on the edge of his dirty bed, a bottle of sleeping pills in one hand and a glass of water in the other. His eyes were empty. His voice was a broken whisper.
"…What's the point anymore?"
He poured the pills into his palm. Twenty white tablets. Enough to end everything.
Just as he raised his hand to his mouth, a bright pink holographic screen exploded into existence right in front of his face, glowing intensely in the dark room.
[Ding!]
The Petty Gacha System has awakened!
Host: Kang-Dae
Title: Pitiful Zero
Lust Points: 0
Humiliation Level: God-Tier (MAX)
A silky, mocking female voice filled his head, dripping with sarcasm and fake pity.
"Oh my god… look at this sad little ant. Thirty days of crying in your dirty room, staring at memes about your tiny useless dick, and now you're about to swallow pills like a drama queen? Pathetic. Truly, truly pathetic. Even I feel embarrassed watching you."
Kang-Dae froze, pills still in his palm. "W… what the fuck?"
The voice laughed lightly, cruel and playful at the same time.
"I'm the Petty Gacha System, born from the rage of every man who's ever been laughed at for having a small cock. And you, Kang-Dae, are my favorite kind of host — a complete and utter failure. But… I really don't want to watch you die before I get to have some fun. So here's a little gift. Because seeing your crying face is honestly ruining my mood."
A flashy pink and gold window appeared with spinning effects.
Because your humiliation has reached legendary levels, you've earned ONE FREE Legendary Gacha Pull!
Don't waste it, little ant. Pull before I decide you're too boring even for me.
Kang-Dae stared at the screen in disbelief. His hand trembled so badly the pills spilled onto the floor. Without thinking, he reached out and tapped the glowing "PULL" button.
The screen went wild. Colors exploded. Dramatic music blasted in his mind. A seductive announcer voice boomed:
"Pulling… Pulling… MEGA JACKPOT!"
[Legendary SSSS+ Grade Reward Acquired!]
The Serpent's Core
Description: The ancient core of a supreme lust demon that once ruled kingdoms through pure sexual domination. Upon integration, it will completely rebuild the host's body from the inside out — increasing height, muscle mass, bone structure, facial features, skin quality, and most importantly, granting a monstrous, powerful upgrade to your manhood, stamina, and sexual aura. No more shame. No more laughter. Only raw, overwhelming, destructive pleasure.
Warning: The transformation will be extremely intense. Try not to cum from the process itself, loser.
White-hot fire erupted through every inch of Kang-Dae's body.
"AAAAAAAAAAGHHHHHH!!"
He collapsed onto the floor, back arching violently as unbearable heat and pleasure tore through him. Bones cracked and lengthened with loud pops. His spine stretched rapidly, adding almost twenty centimeters in seconds. Narrow shoulders widened explosively, tearing his old t-shirt apart. Thin arms ballooned with thick, dense muscle. His chest expanded into powerful, defined pecs while sharp, chiseled abs carved themselves across his stomach like stone.
His face transformed next. Jaw became sharp and masculine. Cheekbones rose. Lips turned fuller and more sensual. His dull eyes gained a dangerous, predatory gleam. Wet, messy hair now framed a devastatingly handsome face that could make women weak with a single look.
But the most mind-breaking changes happened between his legs.
His cock, once the source of endless ridicule and shame, surged with violent force. It swelled thicker, longer, and heavier at an alarming speed. Veins bulged along the rapidly growing shaft. The head flared into a fat, aggressive, perfectly shaped crown. His balls grew fuller and heavier, churning with raw, potent energy. The sheer size and weight made his pants rip at the seams as the massive organ strained outward, thick and heavy even while only half-hard.
Kang-Dae gasped and moaned uncontrollably, hips bucking wildly on the floor as waves of overwhelming pleasure crashed through him. The sensation was so intense that he nearly orgasmed multiple times during the transformation, clear precum already leaking heavily from the swollen tip of his new monstrous cock.
When the fire finally subsided, he lay there panting, covered in sweat, his new deep and sexy voice echoing in the small room.
Slowly, he pushed himself up and stood.
He was tall now. 190 cm of pure, lean, powerful muscle. Broad shoulders, narrow waist, long strong legs. His face in the cracked mirror looked like a dark god — sharp, handsome, and dangerously attractive.
And hanging heavily between his powerful thighs was the real masterpiece.
Even soft, his new cock was massive. Thick, long, veiny, with a heavy pair of full balls beneath it. The sheer size made it swing slightly with every movement, the weight impossible to ignore.
Kang-Dae stared down at it, eyes wide with shock and dark excitement. He wrapped one large hand around the thick shaft, barely able to close his fingers around its girth.
"This… this is a fucking monster…" he whispered hoarsely, voice low and rough.
The system's voice returned, laughing with pure delight.
"Not bad at all, my favorite little ant. From sad tiny shrimp to a goddamn serpent in under five minutes. I almost came watching that transformation myself. How does it feel knowing you can now ruin any girl you want?"
Kang-Dae looked at his reflection again. The pathetic, broken man from thirty days ago was gone.
In his place stood something dark. Something powerful. Something hungry.
The system chimed once more, tone turning wicked and promising.
"Oh, and one last thing… Mi-Cha and Ji-Hoon are throwing a big party at the university dorms tomorrow night to celebrate one month since they 'freed' themselves from you. Everyone will be there. All your old friends. All the girls who laughed at the memes."
A dark, predatory smile slowly spread across Kang-Dae's new devastatingly handsome face.
The rain was still falling outside his window.
But the pitiful zero had finally died.
And the real game was about to begin.
