Vol 1 CHAPTER 1: My Girlfriend Got Stolen Today【Volume 1: Preparation Arc】

It sounds like something out of a manga, but I literally just watched my girlfriend walk out of a hotel with some stranger.

‘A—’

It was both our voices overlapping in that sound, but there was absolutely nothing happy about it.

We headed to a family restaurant nearby to talk. But as I sat there, completely speechless, my girlfriend’s voice came like a machine gun delivering an execution order.

“I’ve fallen in love with someone else. So let’s break up.”

I couldn’t say anything back.

We eventually agreed that we couldn’t have a proper conversation right then and there, so we called it quits for the day. I went home and collapsed on my bed.

And then—

“AAAAAAHHHHHHHHH?!?!”

Yeah. I screamed.

My mom shouted up from downstairs, “What on earth?!” so I yelled back “Nothing!” and she replied, “Keep it down! You’re bothering the neighbors!” She probably figured it was just typical teenage angst. Lucky for me, she let it slide.

Okay, so after screaming myself hoarse, I sat there and thought about my situation.

My name is Arata Kudo.

I’m a second-year high school student. Aggressively, painfully average.

The only thing I was ever proud of was that I had a girlfriend—but I just lost her. Our relationship lasted three months. Yeah. That’s humiliating.

I was the one who confessed to her.

I went in ready to get rejected, but somehow… it actually worked. And I got so drunk on victory that I completely dropped the ball on the whole “dating” part. Apparently, that was my mistake.

In those typical netorare manga and light novels, the protagonist usually screams something like “But I didn’t do anything! Why?!” But honestly? If you do nothing, you get dumped. It’s basic math. If you’re not doing good things, you’re not doing bad things either—you’re just a waste of space. Why would someone waste their precious time on a person who’s interchangeable with a cardboard box? That’s just time efficiency.

So yeah, I understand exactly why I got dumped. I should’ve been glued to her 24/7, hovering around like a swarm of gnats on a summer evening. I have nothing but regrets.

In the end, we broke up without ever really doing anything a real couple does. All we did was go on a few dates and chat a little at school. That was it.

And yet those bastards screwed?!

My mind went straight to the gutter.

I’d seen them walking out of that hotel together. There was only one thing that could mean.

They’d had sex.

With someone who wasn’t me.

“OOOOHHHHHHHHHHH?!?!”

This time, I heard my mom’s real voice screaming from downstairs.

Vol 1 CHAPTER 2: The Nature of Males【Volume 1: Preparation Arc】

So here’s what I want to talk about: the ecology of “males” in the natural world.

I’m sure most people have watched nature documentaries at some point. You know those scenes where male animals fight each other? Ring any bells?

They’re fighting over females, nine times out of ten.

They fight to pass on their bloodline. And only the victor gets the privilege of breeding with a female. That’s it.

So fundamentally, males are creatures that cannot tolerate other males. Look at a lion pride—there are ten females, but only one male. Within the group, the right to impregnate females should be held by as few individuals as possible. That’s the natural order.

Oh, and here’s another thing: the human male’s genitalia are literally shaped to rake out competing sperm. If you can’t visualize that, ask your dad. (That’s probably embarrassing for you, but the point stands.) This whole biological reality proves just how intolerant males are of competition.

But here’s what we can’t forget: humans are still natural animals. We didn’t stop being animals just because we built civilization on top of ourselves.

The characteristics of males haven’t changed one bit from our wild ancestors.

So what I’m saying is—

“Men absolutely hate the idea of their woman getting fucked by someone else. It literally kills them.“

I hate how true that is, but it’s an absolute law of nature.

When the person you’ve marked as your mate gets stolen by someone else, the sense of defeat—the shame, the helplessness. It’s like your entire existence is being negated from the ground up. The despair is beyond imagining.

And that emotion? You could call it “desperation.” And I’d bet most men in this world have felt it. Nobody wins every battle over a woman.

“Ugghhh, gack, ah—aaahhhhhhhhh?!”

My suffering continues endlessly.

This is what they call “brain destruction,” apparently.
