Jin Seoryang lived the kind of life that could only be described in one word: average.
At twenty-one, he was a college dropout, working night shifts at a convenience store, and spending his free time reading webnovels and scrolling through spicy manhwa panels. He had no girlfriend, no prospects, and worst of all—he was still a virgin.
"Man… if only I could transmigrate like those protagonists," he muttered as he carried a plastic bag of fried chicken across the street. "Get a system, meet some beauties, fuck them and become OP… Hah. As if life works like that."
That's when he heard it.
HOOOOOOONNNK!
Blinding headlights. Screeching tires. A monstrous truck barreled toward him, its grill reflecting his stunned face.
"Wait—TRUCK-KUN?!"
BANG!
The world turned black. His body flew, pain shattered his bones, and his fried chicken scattered across the road like fallen feathers. His last thought before consciousness faded was bitter:
"…Damn. I really died a virgin."
When Jin Seoryang opened his eyes again, the pain was gone. Instead, he found himself lying on rough dirt, beneath a crimson sunset. Towering mountains cut the horizon, and the air was thick with the scent of herbs and steel.
He sat up, dazed.
"…This… isn't a hospital. Did… did Truck-kun actually… isekai me?"
For a moment, he just sat there dumbfounded. Then, instinctively, his eyes began to roam.
A dirt path stretched in front of him, packed and worn from countless footsteps. On either side grew wild grass and strange flowers he couldn't recognize. Further away, crude wooden fences marked farmland, with rice paddies glistening under the crimson light. Smoke rose from what looked like a distant village..
"…No way. This looks just like a murim manhwa…" he muttered, swallowing hard.
He turned his head left, only trees and rocks. He turned right, more wilderness. His gaze swept further along the dirt road… and then he froze.
Someone was walking toward him.
It wasn't just anyone. It was a woman.
She looked to be in her thirties, her beauty seasoned rather than girlish. Her long, dark hair flowed down her back, her pale skin radiant under the fading sun. Her robes hugged her full, mature figure,large breasts, slim waist, and hips that swayed with every graceful step. A small sword hung at her waist, hinting at strength beneath her charm.
Jin's breath hitched.
"A… a MILF? Right after reincarnation?!" His throat went dry, eyes nearly popping out. "No way. This… this is destiny!"
Just as he was about to drool, a cold, mechanical chime rang inside his head.
> [Ding!]
System Binding Successful.
Welcome Host, to the [Lustful Demon System].
Path of cultivation? Broken.
Orthodox righteousness? Worthless.
From this day forth, you shall walk the Lustful Demon Path where desire is strength, lust is cultivation, and women are the furnaces that forge your power.
Jin's eyes widened. "Holy sh*t… I actually got a system!"
The moment Jin shouted in disbelief, glowing text scrolled before his eyes.

Jin blinked at the glowing panel. He read it once. Then again. Then a third time.
"…Wait. Strength, 9? 5 Stamina, ? VITALITY, 8?!" His voice cracked. "What the hell is this, a power system or a medical diagnosis?!"
His gaze slid further down until it landed on the real insult.
Charm: 2 (Negative riz)
For a long moment, Jin just stared. His lip twitched.
"…T-Two? TWO?!" His eyes nearly popped out of his skull. "How the hell am I uglier than a normie NPC?!"
He grabbed his face with both hands, feeling his skin like he'd suddenly developed tumors. "Bro, I'm not handsome, but I'm not ugly either! Even my mom says I look 'passable in the right day'!"
The system responds:
> [Reminder: Your Charm stat is objectively evaluated. System does not lie.]
"OBJECTIVELY EVALUATED MY ASS!" Jin roared. "Charm two?! That's lower than the guys who comment 'first' on 18+ manhwa chapters!"
His body shook with fury, but then his eyes fell on another stat.
> [Correction: At current Charm level, chances of intercourse = 0%.]
Jin's grin collapsed. His face fell into despair.
"…System… why do you hurt me like this?"
Before Jin could sink deeper into despair, the mechanical voice returned.
> [Ding!]
Mission Unlocked: Tutorial Quest
Objective: Approach the mature woman ahead and say a single sentence to her.
– Reward: +3 Charm, +3 Vitality, +3 Stamina
– Failure: Death.
Time Limit: 10 minutes
Jin's jaw hit the ground.
"…What the f*ck kind of mission is this?!"
He pointed at the glowing screen, as if the system could see him. "You're telling me—if I don't TALK to a hot MILF, I just… explode and die?!"
> [Affirmative.]
Jin staggered back, sweat dripping down his face.
"This isn't even a quest! This is a death sentence! I haven't talked to a beautiful woman in months—no, years! The last time I did was when I asked the cashier in a convenient store for extra chili sauce, and she ignored me!"
The system was merciless.
> [Reminder: 9 minutes, 41 seconds remaining.]
Jin's throat went dry as he looked up the path. The woman was closer now, her mature figure swaying with every step, her eyes sharp and unreadable. She looked like the type who could slice men apart with a single word.
His knees trembled.
"…Goddamn it. This is it. My very first isekai tutorial mission… and it's literally RIZZ or DIE."
He gulped down the knot in his throat, wiped his sweaty palms on his pants, and forced one shaky step forward.
"…Okay, Jin… you can do this. Just… say hi. Just hi. That's it. Easy."
The system chimed again.
> [Hint: A confident greeting will maximize success rate.]
Jin wanted to cry.
"Confident?! Bro, I can't even be confident ordering fried chicken!"
Jin clenched his fists and stumbled forward, every step feeling like he was walking toward an execution ground.
The woman was right there now, close enough that he could smell a faint fragrance of herbs mixed with steel. Her sharp eyes landed on him, her hand resting casually near the sword at her waist.
Jin's mouth opened—then closed. Opened again—then closed. He looked like a malfunctioning robot.
The system beeped coldly:
> [Warning: 30 seconds of silence detected. Mission failure in 9 minutes.]
Jin nearly shat himself. "S-shut up, I'm trying!"
Finally, he squeezed his eyes shut, took a deep breath, and blurted the first thing that came to mind.
"H-HI! NICE WEATHER WE'RE HAVING EVEN THOUGH IT LOOKS LIKE IT'S GONNA RAIN BUT I'M NEW HERE AND—"
He froze. His brain screamed.
"…Oh f*ck, I said too much!"
The woman tilted her head, blinking at him. For a long, terrifying second, Jin was sure he'd be cut down on the spot.
Then… she chuckled softly.
"A strange boy." Her voice was low and smooth, like velvet laced with steel. "But polite enough. You must be from the village."
Jin's soul nearly left his body. She didn't stab me… SHE DIDN'T STAB ME!
The system chimed.
> [Mission Complete.]
– Reward Granted: +3 Charm, +3 Vitality, +3 Stamina
New Stats:
– Charm: 2 → 5
– Vitality: 8 → 11 Third Rate threshold reached!
– Stamina: 5 → 8
Jin gasped as warmth surged through his body. His skin tingled, his chest felt stronger, and… holy sh*t, his breathing didn't sound like a dying donkey anymore.
He stared at his hands in disbelief.
"…Bro… I feel like I just drank three cans of Monster without the diarrhea side effects!"
The system beeped again:
> [Congratulations, Host. You have survived first contact with a woman.]
Jin's eye twitched. "…Why does that sound more like an insult than a compliment?"
Jin was still flexing his hands, marveling at how not pathetic he suddenly felt, when the system chimed again.
> [Hidden Achievement Unlocked!]
– First Contact with a Woman in Murim World
Reward: Skill Unlocked → Demon's Growth
Jin blinked. "…Wait, a hidden achievement?"
The panel lit up:
Skill Unlocked:
Demon's Growth (Passive): Every time the Host successfully engages in sexual intercourse, a random stats will permanently increase.
Jin's jaw dropped.
"…WHAT THE HELL KIND OF SKILL IS THIS?!"
He pointed at the glowing letters, sputtering. "Other people get Sword Arts, Fire Palms, Lightning Cultivation Manuals—and I get… SEX = LEVEL UP?!"
The system replied in its usual deadpan.
> [Correction: Sex = Permanent Power Increase. Your path is Lustful Demon, not Righteous Hero. Please keep your pants ready.]
Jin nearly fell over. His face turned red, then pale, then red again.
"…So what, I'm supposed to f*ck my way to the peak of martial arts?!"
> [Affirmative.]
"…Holy sh*t. This… this is either the best system ever invented… or the horniest curse in existence."
He looked up at the woman, still walking slowly toward him while watching him, her eyes calm and unreadable.
His heart thumped. She's literally right there… and the system wants me to start my grind with a MILF boss-level tutorial?!
Jin swallowed hard. "…Goddamn it. Truck-kun didn't kill me… he just gave me the greatest DLC ever."
