Who in their right mind would thread through a notebook

"Damn, what terrible luck!"

Lin Yu, sporting a hairstyle reminiscent of Kyo Kusanagi and puffing on a cheap cigarette, cursed bitterly in pain.

He couldn’t understand why he had transmigrated into this world.

When others transmigrated, they either ended up in a cultivation world, slaying thousands with a single sword strike, or traveled back to a historical dynasty, altering history and seizing power.

At the very least, they’d go back a few decades, leveraging their knowledge of the future to get rich and build a harem.

But why was he the unlucky one who got stuck in a hentai manga?

And not just any hentai—a goddamn NTR (cuckoldry) type!

To make things worse, the original owner of the body he transmigrated into was the blond-haired antagonist who cuckolded every male lead in the story!

As a devout "Pure Love Warrior," Lin Yu felt the urge to castrate himself on the spot!!!

Recalling the manga’s plot—where the blond antagonist used every dirty trick to steal heroines away from their rightful partners—Lin Yu, a staunch believer in pure love, couldn’t stomach it.

The final page of the manga, depicting four stunningly beautiful girls in obscene wedding dresses, heavily pregnant with utterly broken expressions, filled Lin Yu with nothing but disgust and revulsion.

As a true Pure Love Warrior, he absolutely refused to let such a thing happen.

Even though he had transmigrated into this disgusting hentai without the golden finger (cheat ability) that every transmigrator was supposed to have, Lin Yu was determined to stop this tragedy at all costs.

Not for any grand reason.

Just for the sake of his former identity as the moderator of the "Pure Love" forum, he swore to ensure these four unfortunate girls would stay with the ones they truly loved, walking hand-in-hand into a blissful marriage!

As for NTR bastards?

He’d slaughter every last one of them!!!

Fuming, Lin Yu took one last drag of his cigarette before flicking the butt to the ground and crushing it underfoot.

The moment his shoe twisted against the extinguished stub, an eerie sense of déjà vu washed over him.

It was a feeling of repetition—as if he had been here before, performing this exact same motion of stamping out a cigarette in the exact same way.

The same dark blue school uniform pants, the same pristine white shoes, even the angle of his foot and the tilt of his gaze matched perfectly with a memory he shouldn’t have.

Lin Yu found this uncanny familiarity absurd.

This was his first day at this school, and this was the first cigarette he’d smoked here. There was no way he could have any memory of smoking in this spot.

It couldn’t be the original owner’s memory either—the shoes he was wearing had been cleaned by him just yesterday after transmigrating.

That slob of a predecessor had never worn shoes this clean in his entire life!

The bizarre sensation vanished as quickly as it came, fading away in less than two seconds—like darkness in a desk drawer disappearing the instant a flashlight flicked on.

Lin Yu’s mind was in a daze. He had a vague suspicion about the source of this sudden familiarity, but he couldn’t confirm it yet.

Still disoriented, he stepped out from behind the wall—only for the eerie déjà vu to strike again the moment he saw the schoolyard. This time, it was even stronger.

The teachers and students milling about the field, the eight-story teaching building straight ahead, the flagpole, the podium—even the clouds and the sun in the sky—all felt unnervingly familiar.

It wasn’t just that he had seen these things before.

It was as if he had witnessed this exact moment—every person, every object positioned precisely as they were now.

He had seen this exact scene!

At that moment, Lin Yu finally realized—and confirmed his earlier suspicion.

Holy hell.

He had entered the hentai’s storyline!

Once he grasped that he was now part of the manga’s plot, Lin Yu instinctively tried to recall the events depicted in it.

Though it had been a long time since he’d read that hentai, the two eerily familiar scenes served as triggers, and he was confident he could piece together the plot.

Time ticked by as Lin Yu’s frown deepened. Then, in a flash of inspiration, his eyes snapped open.

Shit!

He had to go save someone—NOW!!!

His legs moved before his thoughts could fully form. The moment he remembered what came next, Lin Yu sprinted toward the teaching building with all his might.

Because according to the manga’s plot, the first heroine was in grave danger right now!

Here’s how it went:

The first heroine was cornered by three delinquents in a secluded alleyway.

The leader, a purple-haired punk, lusted after her beauty and was about to assault her.

Then, the original blond antagonist (now Lin Yu) coincidentally passed by.

Upon seeing the heroine’s beauty, he let his depravity take over, pulling off a classic "Let go of her, you scum—I’ll take it from here!" move.

After groping her thoroughly, the bastard still wasn’t satisfied, so he took compromising photos of the heroine and blackmailed her into meeting him at a love hotel after school.

From then on, the heroine, trapped by his threats, fell completely into the blond’s clutches—eventually degenerating into nothing more than a plaything.

Recalling this plot, Lin Yu felt nothing but contempt for the original scumbag. But he also realized something critical:

Even without the blond antagonist’s interference (i.e., himself), the heroine would still end up violated by those delinquents.

Holy hell!

Daring to pull NTR crap in front of the Pure Love forum moderator?

Did they have a death wish?!

Filled with fury, Lin Yu’s body surged forward with terrifying speed as he raced toward the teaching building.

But even as he ran, a crucial question nagged at him:

Where exactly was that secluded alley where the heroine was being cornered?

From the original blond’s memories, this high school was pretty large, with several remote pathways. Which one was it?

After a moment’s thought, Lin Yu realized the manga never bothered with such trivial details.

That meant he had to find clues from his own situation.

Forcing himself to calm down, Lin Yu began analyzing logically.

According to the manga, the blond had stumbled upon the heroine while on his way to do something.

So—what had he been about to do before this?

Lin Yu racked his brain but couldn’t remember what he’d planned after finishing his cigarette.

As he neared the teaching building, panic set in.

If he didn’t know the exact location, searching every alley would take too long—by then, it’d be too late!

Just as despair crept in, Lin Yu spotted a student walking toward him, holding a half-finished bottle of soda.

The pale green packaging flashed in Lin Yu’s right eye (unobstructed by his blond bangs), and suddenly, it clicked.

Right!

He’d just eaten in the cafeteria, but the soup was too salty—he’d wanted something sweet to drink!

And there was only one place in school to buy sweet drinks:

The campus convenience store!

Thinking about where the female lead might be cornered, Lin Yu initially felt a surge of excitement, but soon he noticed something off.

The path to the school convenience store?

How could that route possibly be deserted?

The female lead was supposedly trapped by three delinquent students on a secluded path—that didn’t add up!

After a moment of reflection, Lin Yu thought of another location.

The store!

But not its current spot in the southwest of the school. Instead, it was the old store location in the northwest before it had moved.

Since the store relocated, that area had become a storage space for junk and coal, rarely frequented by anyone.

The original host, the delinquent, likely went to buy water but got the address wrong, ending up at the old store site.

Now everything fell into place!

A place one would pass by while buying water.

A secluded, rarely traveled path.

That had to be it!
