My Job is the NTR Master

Fuck…

What the hell is this? NTR? If you think about it, it’s kind of similar to my own situation.

This one’s on the more extreme side, though.

The last side story I skipped without reading because it shared the same name was exactly this. Good thing I didn’t look at it.

It’s currently vacation. There’s about a month left until the new semester starts. During break, the academy requires everyone to leave. No exceptions whatsoever.

So during this time, I guess I have to prepare for revenge. It’s probably what the old me wanted.

Wait… am I really supposed to NTR the guy who does NTR?

This isn’t some trashy drama. It probably won’t play out that way… right?

I pulled up the quest and job I’d received earlier.

The system wants Lee Taehyung’s complete downfall. It called me here to prevent its own world from being ruined.

System, what’s the reward?

[Will you accept the quest?]

Yes – No –

What happens if I refuse?

A faint tension crackled between me and the system. Mutual distrust, wariness. Couldn’t be helped. If I wanted what I desired…

Accept—

How could I possibly go back when my parents are alive and well here? That would be too huge a loss.

System, open the job window.

What the hell are these weird abilities…? NTR… Everything begins with NTR and ends with NTR.

And it wants me to NTR every single one of the protagonist’s wives…

This is too much. I can’t handle this.

My current stats are dead last in the class. Beating the protagonist with this was impossible.

Aura and mana are fixed at birth. They can’t be raised any further… Huh?

Below the job effect, written in extremely tiny letters—so small you’d miss it if you blinked—was a single line that gave me hope.

*Stats increased through the job effect can break through innate limits.

In other words, mana and aura could rise without any ceiling. A terrifying ability. If I succeeded in NTR, I could become stronger than the protagonist.

Besides, we were still in the early stages of the novel. I could snatch every single one of the protagonist’s future opportunities and equipment for myself.

Might actually be worth trying?

Three days later.

I’d gained nothing. I’d just been working out in my room the whole time… This wasn’t going to cut it. I needed to go to the gym.

“Mom, I’m heading to the gym—”

“I didn’t even want you going to that hunter academy, and now this!”

Mom had opposed us attending the world’s top academy even though we had the talent for it. Looking at my sister, her opposition made sense, but my sister had ignored her and forced her way in anyway. I ended up following her there.

This approach clearly wasn’t working, so I changed tactics.

“Noona~”

“What, you need allowance?”

Ugh… I knew how pathetic it was to act like this toward my own blood. But for the sake of our family…

“Noona, I love you~”

“Fuck—”

Thud!

Uwek— The insane woman. I told her I loved her and she immediately punched me with a mana-infused fist.

It landed dead center on my solar plexus. Even though she was a mage, that mana-covered punch hurt like absolute hell.

What? This actually works?

“Noona~ I love you so much—”

“Hey, fuck, knock it off.”

By the end my eyes were swollen shut and there wasn’t a single spot on my body that wasn’t bruised.

Haha… That was time well spent.

When it hits 100, does she enter the absolute NTR state?

Haha.

My body felt noticeably lighter. I had more strength than before.

“Noona~”

“Ha, seriously…”

Aah… I’d been hit so many times that it didn’t even hurt anym—

It stopped increasing. Why?

So cheap tricks don’t work, huh…

Well, I’ve got plenty of time.

“Here, take it.”

My sister handed me a hundred thousand won, saying she felt bad. To be honest it didn’t seem like guilt—it looked more like she was rewarding herself for relieving stress by beating me. The money came from selling gate byproducts she’d earned while doing hunter prep.

“Whoa, Noona’s the best! Love y—”

“Want to die?”

I snatched the cash and bolted. Gym. Gym. Gym.

Like a zombie, I wandered the streets in search of a gym.

Ah, this is the one. The gym I used to go to. Tucked away in a corner, an old, run-down place. The kind of gym where only the clanging of iron and low, pained groans echoed.

It was exactly the same as it had been a week ago. The smell of heavy iron plates and sweat. Mmm~

“What a beautiful scent…!”

As expected, the smell of a gym was first-class. Since it had been a while, I stood there savoring it several times. Alright, time to get to work!

“Ugh… kgh…!”

Pathetic weight. Muscles trembling violently, screaming like they were about to tear. Fuck, this is the stuff.

System, I’m trying to work out here!

The scream of muscles I hadn’t felt in days… They cried out ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠beautifully. The muscles wept and screamed, their tears flowing out as sweat.

I missed this. Hello again, my muscles—

“What are you doing?”

“Uwaaaaaah!!”

Bang!

Fuck, who is this girl? I was pouring every ounce of strength into tearing my muscles apart and she just barges in.

White hair, blue eyes. A foreigner. Well, it was the hunter era, so the academy had an even higher percentage of foreigners.

Still, interrupting someone’s weight training crossed the line.

I glared at her. She simply stared back with wide, innocent eyes, looking like she had no idea what she’d done wrong.

“What are you doing?”

“Watching you.”

“Why are you here?”

“To work out.”

“Do you know me?”

“We’re in the same class.”

Same class…? So the system that kept beeping earlier was because of her.

“What’s your name?”

“Eh? The first semester’s already over and you don’t know me?”

Side Story 19…

She gets NTR’d too? Just what kind of bastard is Lee Taehyung?

Two years from now, the boy Lucy Stena falls for gets attacked in a gate. Lee Taehyung secretly beats the boy into a coma, then while comforting the devastated Lucy who’s nursing him, he corrupts both her mind and body… The textbook definition of NTR. Dominating the mind first, then claiming the flesh.

Wow… I’m actually speechless. At this point, maybe Lee Taehyung is the guy who invented the term NTR.

What a lunatic.

Anyway, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠that same girl was now working out right in front of me.

For the sake of my future, I needed to seduce her.

Sorry about this. I’m not going to do anything weird like assault her or whatever…

“Ugh… kgh…”

I see. That’s actually pretty admirable. The mindset of clearly recognizing the limits of your own abilities and working to overcome them. Respect.

In that case, I could help. I knew self-defense techniques, after all.

Surprisingly, ever since I was young I had learned every martial art there was. I had a strange hobby of mastering every bladed weapon from longswords to daggers.

It ended up helping a lot when I became a detective.

What she wanted was probably simple self-defense to protect herself while casting spells in close quarters. That was why she came to the gym to build strength.

“Hey, want to learn some self-defense?”

“Se… self-defense?”

Her Korean was slightly awkward. She might not have learned that word yet.

“Fighting to protect your body.”

“Mm… Yes! I want to!”

Her eyes sparkled instantly. We moved over to the separate mat area.

“Alright, I’m going to grab you. Try to defend yourself.”

“Okay! Got it!”

She took a stance. Basic boxing posture. So she had learned boxing.

I rushed toward her at high speed. She threw a jab. It was sloppy and powerless.

So slow I could see it perfectly.

I dodged the jab easily and slipped inside her reach. I was about to tackle her, but maybe I’d underestimated how weak my body was yesterday…

Thanks to the level-up, I closed the distance far faster than expected. I missed the timing to stop and crashed straight into her, sending both of us tumbling to the mat.

Something soft and warm filled both my hands completely.

Because she’s a foreigner, they’re a bit… Wait, that’s not important right now.

Cancel cancel cancel!!!

“S-sorry!”

Thump. Thump.

I couldn’t tell if it was my heartbeat or hers, but it pounded loudly and intensely. I was too embarrassed to get up.

She was startled too and grabbed my head, pressing it down even harder.

“Mmph… mmph!”

“Aah… I’m so sorry!”

She panicked even more and kept apologizing, but her flailing only pressed my face deeper into her chest.

Her face burned bright red. She was sweating, completely flustered and unsure what to do.

Lady, please let go of my head!!

That was when the system spoke.
