Yesterday's Enemy 2: My Past Life Self
After getting out of prison, I hadn't stepped foot outside the house. My hobbies were limited to reading web novels or binge-watching OTT shows.
In particular, I loved survival reality shows that had taken the world by storm, like Squid War, Black and White Cooking Battle Royale, Genius Engineer, and War of Blood.
Maybe it was because I'd actually survived in a real prison, but I could immerse myself in the characters on those shows like no one else. Five years in prison. Short if you think about it, long if you don't. It was there that I'd self-taught the essentials of survival.
I was shocked to see those same strategies play out perfectly in Genius Engineer and Black and White Cooking Battle Royale. Winners of survival shows all share one key trait: the eye to distinguish between people who'll benefit you and those who'll harm you.
Those who nail it from episode one always end up as the champions. I have a good eye for people. Avoid the harmful ones, get close to the beneficial ones—that's the golden rule of survival.
The same applies in this novel world. When there's someone you need to get close to, you don't just suck up to them outright. Raise your own value, build rapport, make them curious about you. Don't extend your hand first. Make the target reach out to you.
And Egenam, Surviving the Cult Religion Academy is my new survival game. I can craft a cooler ending than the original protagonist, Hadojin.
"Hado mong… called me first? Not a bad signal."
Hado mong is a half-ogre born between the Cult Leader and an Inhuman female 'Petit Ogre.' He's two meters tall with the strength to fold a charging bull in half. People mistake him for a melee dealer swinging that massive axe, but he's a mesmer.
A mesmer who manipulates minds—it's a magic ability bordering on outright fraud. Erasing U Jeong and her mom Kim Min-jung's memories? That was the Cult Leader's mesmer power.
Anyway, a dream you'll never achieve—might as well live it out in my nightmare. Waking up from a dream where you can do whatever you want would just make you more miserable.
Hado mong's sleazy line had burned itself into my brain. Manipulating dreams, deluding people with illusions, controlling and exploiting them… He was the worst nemesis tormenting protagonist Hadojin throughout the mid-game.
"…Hado mong's taking an interest in me."
Hado mong pokes at weaknesses—over and over and over. The moment you expose yours to him… you're done for, used and butchered.
But what if it's the other way around?
The phone rang again. I gently laid the passed-out U Jeong on the bed and headed to the bathroom. I picked up, and Hado mong's growling voice rumbled low through the receiver.
-If you hang up again, I'll kill your mom An Hyeonmi right in her flower shop.
"Who gives a shit if the Cult Leader's cumdump dies."
My cold reply drew a barking laugh from the other end.
-As expected… you knew? Most guys freak out learning the mom who raised them is the Cult Leader's cumdump, but you're different.
"What's the deal?"
-You… dropped out of the successor race on purpose, right?
"……"
In the novel, Hadojin's early dropout from the successor competition was a big deal. He was the only Inhuman half born between the Cult Leader and a demon, after all. Readers everywhere were probably monologuing How could this happen?! and hyping themselves up.
"What do you wanna know?"
-Why you dropped out on purpose… that's what I'm curious about.
"Not telling."
-Aren't you curious who your real mom is? I can tell you.
"Nope."
A flustered cough came through the line. Hado mong was trying to pull me to his side now, leveraging our shared status as the only Inhuman halves among the seven brothers. Building rapport off that common ground.
With the successor rivalry heating up, pure-blood brothers were starting to shun him. He hadn't awakened yet—just a big, strong brute.
His voice growled deeper.
-Don't you need someone to protect you? I can help.
"Can't even protect yourself without awakening. Protection's a two-way street—levels have to match. I'll take the offer as a friendly gesture for now."
-Cocky little shit. Know who my maternal family is? Hado—
Click. Hung up again. I'd scratched his ego just enough and left him with the promise to consider his proposal favorably. He'd be dying of curiosity over my confidence right now.
Villain or not, if I could flip him to my side… not a bad move. His stepmom who raised him, Josephine, was dangerous. A noble from the Holy Kingdom of Almadia, brother nation to the Daehan Cult State. And the Cult Leader's first cumdump.
Picture the Holy Kingdom of Almadia from the fantasy world—blondes, redheads, silver-haired whites in a medieval setup. If Daehan Cult State is the East, Almadia's the West.
But their magic-over-science taboo keeps quality of life below Daehan's. Almadia expats here end up in convenience stores, factories, construction—shunned and sneered at.
Late in the novel, when fairies invade, Almadia's magic legion plays a key role. Led by none other than the Iron-Blooded Empress Josephine.
Once Hado mong fully awakens his mesmer powers and gets her backing, he becomes the trickiest foe among the brothers.
"You're… on hold for now."
I saved his number. No need to auto-enemy future foes.
"Wait. Hado mong's a half-ogre, right?"
If I fed Harina 'Ogre Blood' to max her tank potential, then bathed her in 'Dragon Blood'…?
Pretty fun idea.
"Yu-jeong-ah… time to wake up."
I gently stroked U Jeong awake. Who'd guess the future Demon King 'Rust' could be this cute?
"Haaang… Dojin oppa. Oppa-ha… oppa… daddy… don't die…"
"Daddy, don't… die…"
She murmured in her sleep, tears streaming as her eyes fluttered open. Guess the mesmer-sealed death of her dad bubbled up from her subconscious.
"Oh? Why am I crying? Oppa!! I must've passed out! Sex… was too good. What do I do?"
U Jeong wrapped around my neck, peppering my cheeks with kisses.
"Look how swollen I am down there. Hehe."
She'd slipped her dress back on, acting casual, but kept fidgeting with her crotch. No wonder—I'd deflowered her rough.
"Ice cream?"
"Yes!"
She hooked her arm in mine.
"Was I… okay? Sorry if I sucked 'cause I'm a virgin… and my tiny tits too."
"Nah, you were the best. First time I've cum seven times in a day."
"R-really?"
"Yeah. For real."
Her face flushed beet red as she buried it in my chest. Ears too—adorable.
She chattered nonstop as we walked: school life with Harina, friends, mostly praise for me.
"Oppa gets more charming the more I look. Quiet but sweet, scary but your smile's pretty. When you beat those punks earlier, my heart was gonna explode. Like a knight from old tales saving the princess."
Knight. That word made me study her closely. Her eyes sparkled with pure admiration.
It wasn't just physical attraction—something deeper, fated, stirred in her for me.
The ice cream shop was empty. She winced sitting on the wooden chair, crotch still sore.

Moments later, U Jeong started doodling on a napkin. Absentminded, but I couldn't look away.
Two sharp swords crossed, a roaring lion's face above—intricate, regal emblem.
"Yu-jeong-ah, what's that?"
She blinked down at it, realizing.
"Huh? Oh… dunno. My hand just moved on its own. But… it feels familiar. Like I've known it forever… warm, reassuring?"
She tilted her head, tracing it with a finger. Crest of a lost kingdom predating the Daehan Cult State. A fragment from her deep subconscious.
Right then, the server bringing our parfaits and injeolmi snowflake ice cream blushed at my face.
"Your parfait and injeolmi snowflake ice cream. Um… are you a model? You're so handsome…"
I smiled lightly to thank her shy compliment—then U Jeong's vibe shifted instantly.
Her sunny smile vanished. Eyes iced over, grip tightened on my arm—nails digging in.
"Hey! What the hell? Can't you see I'm sitting here? With that goblin face."
Her voice was soft, but laced with razor-sharp killing intent. The server paled, overwhelmed.
"S-sorry… I just…"
"Just? 'Just' while eye-fucking him like a perv? Before I gouge your eyes and shove 'em down your pretty throat, fuck off."
Smile on her lips, but eyes dead cold. A glimpse of future Demon King 'Rust.'
The server nearly cried, bowed, and fled.
"Hmph. Where do goblins like her get off buzzing around."
U Jeong turned back to me, beaming innocently again.
"Oppa, surprised? Sorry. Hate bugs on you… You can only look at me. Love only me, touch only me. No other girls. Or… I might do something to them.♥"
She nuzzled my cheek cat-like, all aegyo. But those were chilling threats, not sweet nothings.
I stroked her hair calmly.
"Yu-jeong-ah. But… my dream's building a harem. What to do?"
My bold declaration left her jaw dropped.
"Harem? Hing… meanie…"
"My dream's a world where everyone's happy. If you hog a stud like me, how sad for the rest? Right?"
"W-well, yeah, but."
She pouted up at me, lips in an M.
"Hiiiing. Okay, oppa. You're too cool!"
I petted her head, hugging her waist lightly.
"Yu-jeong-ah. Around others, stay cute and sweet like now. No hurting anyone without my say-so."
I had to dominate and control her. Not suppress her dangerous instincts—but be the only one who could unleash them.
…What if I tame the Demon King beforehand? Gaslight the shit out of her…
"Me, hurt someone?"
"If it happens, you need my permission. Got it?"
Her eyes lit with awe. Like a devotee receiving divine word, she nodded ecstatically.
"Yes…! Yes, oppa! I'll do whatever you say!♥ But… can we do it again?"
She bowed her head shyly smiling. My Incubus Power skill Seductive Semen was already reeling her in.
Lucky she hooked up with me, in a way. Whatever unfolds, ongoing relations could make one of the Four Great Demon Kings, 'Rust,' fully mine via Seductive Semen.
I stroked her hair softly, smiling satisfied.
"Good girl. Good girls get rewards, right?"
We left the cafe, heading back to the motel. Door barely shut, U Jeong pounced, kissing fiercely—way more intense and blatant than before.
She shoved me onto the bed, straddling me.
"Oppa…♥ This time, I'll lead. You just… take the pleasure I give.♥"
She stripped herself. Dress pooled on the floor, revealing her slender nude form.
She rubbed her small tits in my face.
"Oppa, my tits… small, but enough to excite you, right?♥"
I hugged her waist, sucking a nipple.
"Hiiit!♥"
She clutched my head, twisting her hips. Then yanked off my pants, freeing my rock-hard cock.
"Wow… oppa's cock is always so majestic. Housing this inside me… I'm the happiest girl alive.♥"
No hesitation—she aligned and sank down slowly.
"Huuuugh…!♥"
Her tight, hot depths greedily swallowed me. Pain and pleasure mixed in her moan as she started riding.
"Haa… haa… oppa…♥ How's my pussy? Gripping you tight?♥ You're mine. Can't give you to anyone. This pussy exists only for oppa's cock.♥"
Every word dripped obsessive chills. I took it all, dominating her body and soul.
As she climaxed and collapsed on me, I whispered in her ear.
"You're mine, U Jeong. Forever."
