I am the protagonist of NTR novel

Do you know what's worse than not getting paid for the month?

An accident? Sounds painful.

Drowning in debt? Man, that must be rough.

But for me, those things, while painful, are something I can get through—given enough time.

There's one thing, though, that completely broke me. And it was anything but funny.

"I'm sorry, Mr. Kai. Your younger brother… he couldn't fight the illness any longer."

The pain of the soul is far worse than any physical suffering.

"..."

I could only stay silent, staring at my brother's lifeless body.

His eyes—empty, void of life. Proof that he no longer existed in this world.

The doctor beside me didn't know what to say either, so he just handed me the hospital bill.

"I know this is definitely not the right time to give this to you… but this is my job. My apologies."

"It's fine…"

I took the bill and looked at the numbers on it.

Even though my brother had health insurance, those bastards never actually paid for treatment, so having it was basically useless.

So when I saw the final amount, I could only keep my mouth shut.

I already knew it would be expensive, but still…

This amount is… massive.

I don't even know if I can afford it.

Suppressing the unfairness boiling inside me, I turned to the doctor.

"My brother… did he say anything before he passed?"

"He… he said he loved his older brother. And that he hoped to recover soon… so he could help pay off the debt."

Hearing that, I had no words left to say.

Moments later, I found myself outside, looking up at the night sky.

"..."

Tears streamed down my face. My nose ran, making me look more miserable than ever.

"First my parents… now my brother, too?"

My whole life has been a joke. Truly.

Born into poverty, buried in debt, and now left alone to carry all the pain by myself.

Why don't I just die, too?

At some point, I realized I had walked back to my house.

'I ended up here…?'

A tiny, broken wooden house—left behind by my parents. Never improved, never repaired.

I stepped inside and silently looked around.

From the toothbrush to my brother's cup…

Every little thing.

Then I turned to his room.

It didn't have much, but I had given him everything I could.

And now… this place was nothing but a memory.

Lying down on my bed, I stared at the ceiling.

"..."

I didn't know what to do anymore. I had a job, sure, but what was the point now? To pay off debt?

I'd rather die. Maybe I'd get to see them again in heaven or something…

After a while, I sat up and glanced at my brother's desk.

I flipped through his notebooks and looked at his books.

"...?"

One book caught my eye. A green one.

"...Did my little brother seriously buy this?"

Cuck Hell World. That was the title.

Just from the name alone, I knew something was off.

Taking a deep breath, I decided to read it.

Ten minutes later, I closed the book and sat in the corner, deep in thought.

"...Little bro, you seriously bought a hentai book about getting cucked? For real?"

Sitting there for a moment, I let out a dry chuckle and placed the book back.

Then, I took one last look around my brother's room.

And quietly closed the door.

Three days later, my brother's funeral took place in silence.

No fancy coffin, no expensive wreaths—just a simple white cloth wrapped around his body.

I couldn't afford a proper funeral, so a few kind neighbors helped me dig a small grave behind the house.

As the last handful of dirt fell, I just stood there, staring at the freshly covered mound. No tears, no cries. Maybe I had already cried myself dry the night before.

One by one, people left, until only I remained.

I sat there for a long time, unmoving.

It wasn't until night fell that I finally dragged myself back inside, my body so exhausted that I couldn't even think anymore.

I collapsed onto my old bed—too tired to take off my shoes, too tired to pull up the blanket.

"Sleep well… little brother…"

Those were the last words I mumbled before sleep pulled me into its deep, empty void.

***

"Hey... Wake up..."

I suddenly heard someone calling me.

"Hey, wake up… We've reached the last stop."

I slowly opened my eyes, my mind hazy, my body feeling heavy as if I hadn't fully woken up yet. But instead of my old, worn-out ceiling, what I saw was… a train car?

Soft cushioned seats, dim warm lighting, large windows reflecting the light from outside. A train? Where am I?

"Sir? It's time to get off. The train won't go any further."

That voice again. I turned and saw a train conductor standing in front of me, his expression calm but slightly urging.

Still confused, I got up and stepped off the train on instinct.

The moment my feet touched the platform, I heard the sound of metal wheels rolling—the train slowly departed, leaving me alone at an unfamiliar station.

It took me a few seconds to realize that something was… off.

I looked down at my hands—smaller, more slender.

Then, I caught a glimpse of my reflection in the window beside me—bright green hair.

I touched my face—the features were softer, younger. A gentle, almost innocent look.

The clothes on my body were different too—a neatly pressed academy uniform, with an emblem that felt strangely familiar.

Wait…

I stared at my reflection for a moment longer.

Green hair, golden eyes… A kind and naive face… An academy uniform…

No no no no NO NO NO NO!!

NO FUCKING WAY?!

Isn't this the protagonist of Cuck Hell World?

...

ISN'T THIS THE PROTAGONIST OF THAT SHIT?!??

WHAT?!?

"Fuck this! What the hell is going on?!"

I screamed in the middle of the station, gripping my unfamiliar green hair.

"No way… How did I end up here?! Am I dead? Or is this some kind of sick dream?!"

I rolled around on the ground like a lunatic, punching the floor in frustration. I slammed my head against a lamppost, sprawled out in the middle of the platform, then convulsed like a dying fish.

"Goddammit! Don't tell me I actually got reincarnated into Cuck Hell World?! Of all the millions, no—BILLIONS of worlds, why this piece of trash?! Who the hell did this?!"

Just as I was about to continue my tantrum, I felt the weight of multiple stares pressing down on me.

I froze.

Around me, passersby were staring—some curious, some concerned, and others whispering as if I were some escaped mental patient.

"..."

I stood up, brushing the dust off my academy uniform.

Taking a deep breath, I muttered, "I need to calm down… Calm down…"

But how the hell was I supposed to stay calm?! This was Cuck Hell World!

At first, I thought it was just a typical harem story—where the protagonist gathered a bunch of girls and lived the kind of life that every pathetic loser dreamed of.

But little by little, I started realizing the horrifying truth.

It was all a trap. A cruel joke.

Every single girl in the protagonist's harem was getting fucked behind his back. Lustful bastards kept appearing out of nowhere with zero logic. A teacher suddenly had a secret lover? A friend got cornered by some random noble? Even the most innocent girl ended up seduced by some sleazy shopkeeper?!

It kept happening over and over, to the point where I couldn't take it anymore and dropped the book halfway through.

But now?

Somehow, in the dumbest way possible, I ended up in this world.

And I only remember half the damn story.

"...I hate this."

Little brother, why did you have this shitty book? And why I'm here?

"..."

Well... Maybe I just... Going, kinda curious how this world work.

Just act like a normal student and maybe... I will not become a guy always get cheat on?

I don't know, just give a try anyway, what worse than that?

Fully ready, I'm going to the academy with full of cautious.
