Chapter 1: I'm the Protagonist's "Roommate"
The moon hung high, and the stars were few. Under the quiet night sky, the once-bustling university town had fallen into stillness.
It was already 3 a.m. Some faint lights still glowed through scattered dorm windows—only those with the determination of cultivators at the peak of ascension could still be battling at their computers this late.
Ning Chu was once again struggling with insomnia.
He sat at his desk, propping his head up with one hand. He wanted to play a game but couldn't focus. He wanted to sleep but his mind was a mess of scattered thoughts. In the end, he just kept clicking through webpages aimlessly, eyes staring blankly at the screen.
"Still not sleeping?"
A deep, slightly hoarse male voice came from above. The bunk bed creaked softly as a tall, broad-shouldered guy climbed down the ladder.
Ning Chu glanced at him but didn't reply, his lips pressed into a thin line.
It had been over a week since he arrived in this parallel world, but he still couldn't get used to it.
To his roommates, that made him seem particularly withdrawn and antisocial.
"We're already two weeks into the semester. Why do you never talk?" the roommate mumbled to himself, heading to the balcony.
Ning Chu sighed quietly and opened his hard drive, pulling up a document file—his R18+ novel.
If there was any upside to being transmigrated, it was this.
He had somehow ended up inside the world of his own novel—a hentai story, the kind of wish-fulfillment webnovel he had written before crossing over.
Who would've thought he'd end up inside something he wrote? If he'd known, he never would've gone with that genre!
Still, the entire novel had come with him, so he could freely look through the plot, characters, and events whenever he wanted.
'Wen Yang…'
The protagonist, Wen Yang, was none other than his roommate—the same guy who just got up to pee.
Unlike the fearless and charismatic Chad in the book, the real Wen Yang was still single and very much a virgin.
Ning Chu quickly skimmed through his novel, matching each character to someone in real life.
'Roommate #2: Wang Jie.'
Wang Jie only showed up in two chapters of the novel, just as a sidekick to Wen Yang. It had taken Ning Chu two whole days just to find that tiny part.
'Roommate #3… oh no, he's a villain.'
Zhang Shaoqing, the third roommate, was the stereotypical rich, blonde-haired bad boy who did all kinds of scummy things. He was the kind of guy even a dog would cover its eyes around.
Ning Chu instinctively turned to look at the back of the room—Zhang Shaoqing's bed.
Despite the character's awful actions in the book, the real Zhang Shaoqing didn't seem like a bad guy at all. In fact, he'd been pretty generous with his roommates thanks to his wealthy background.
So… the protagonist and the villain weren't acting like their novel counterparts. Maybe the story hadn't started yet?
But the thing was—this kind of webnovel didn't really follow a clear timeline. Each chapter was a standalone episode, with the male lead getting into all kinds of steamy "fights" with different girls.
Who knew when the plot would actually begin?
There were four people in the dorm. Wen Yang was the protagonist. Wang Jie was a background character. Zhang Shaoqing was the villain.
'So… who the hell am I?'
Frowning, Ning Chu scrolled rapidly through his novel, scanning for any mention of himself.
Since he shared a dorm with the main character, he vaguely remembered writing something relevant.
'Where is it…'
"Hey, Ning Chu. Go to bed already," a teasing voice suddenly called from behind, catching him off guard. "Reading stuff like that too much isn't good for you."
Ning Chu nearly jumped out of his skin. He slammed the laptop shut and spun around—only to find Wen Yang standing right behind him.
He had no idea how long he'd been there.
Face turning red, Ning Chu felt utterly embarrassed. The main character of his smutty novel had just caught him reading… that exact novel.
He shrank into himself, trying to play it cool. "You walk like a damn cat," he muttered. "Fine, I'll sleep."
Thankfully, Wen Yang didn't seem to realize the story was about him.
"Take care of yourself."
"…"
Ning Chu ignored him, head down, fiddling with his phone.
In this hentai world, everyone was absurdly attractive—and Ning Chu was no exception.
He could only be described as a "trap"—soft features, a youthful baby face. Even though he was already a freshman in college, his appearance made him look like a middle schooler. He hadn't really grown into his looks yet, and he was barely 160 cm tall. With such a petite frame, he could easily be mistaken for a girl.
He could only hope he'd grow a bit taller in the next couple of years—160 cm was just too short for a grown man.
Thankfully, he was straight. His novel didn't include any "man-on-man" or "left and right are all men" scenarios. Otherwise, with how he looked in this world, he might genuinely be in danger.
'Danger?'
That thought made Ning Chu freeze.
His eyes widened, and he scrambled to open his laptop, scrolling frantically through the document until he found a specific chapter midway through the novel.
The gist of that scene was: Wen Yang returned to the dorm to find it empty. When he went to the bathroom on the balcony, he opened the door and discovered a woman showering inside. And from there… a passionate "battle" broke out, as expected.
Ning Chu had never seriously considered the possibility that he might be the "conquerable"-type side character in his own smut story.
'That woman… couldn't be me, right?'
His right eyelid started twitching nonstop, and his lips curled in disbelief.
He kept reading.
The woman ended up living in Wen Yang's dorm. Though they tried to keep their "activities" a secret, they were eventually found out—and then Zhang Shaoqing made his move and cucked the protagonist. Throughout the whole arc, only Wang Jie remained clueless about the mysterious new female presence in the room.
"This plot makes no sense," Ning Chu muttered. "A woman dressing as a guy and living in the dorm? There's no way Wang Jie wouldn't notice. But whatever, I didn't care about the details when I was writing it."
Now though, that plot hole seemed to have... fixed itself.
'What if that woman… was never cross-dressing at all? What if she was just… me? A guy.'
Ning Chu shivered, goosebumps rising all over his arms. He rushed to the bathroom and double-checked—just to be absolutely sure.
Yep. Still a guy.
'No way it's that messed up. I probably just forgot to write in Wen Yang's fourth roommate, and now I've crossed over and filled in the gap.'
That tight knot in his chest finally loosened. He felt a little calmer.
After brushing his teeth and washing his face, Ning Chu kicked off his shoes and collapsed into bed, utterly exhausted.
Why the hell did he write this crap?! God!
Back then, he was just bored out of his mind. Now, looking at it from the other side, it felt downright perverted. And yet, to be fair, he'd never intended to post it online—it was just a guilty pleasure, something for fun. Who would've guessed he'd actually end up trapped inside the damn thing?
'Whatever, don't overthink it. Just go with the flow…'
He pulled the blanket over his head, curling up under the covers.
Since he didn't exist in the original plot, maybe that meant he could live a peaceful life in this strange world. Get through college, then marry a pretty wife. Girls here were, on average, way more attractive than back in his old world.
He might even be able to marry a non-human girl.
A cat girl wife…
His mind started drifting off into fantasies of a blissful future life with a cat-eared bride, full of happiness and pleasure—but the dream was abruptly shattered.
His eyes flew open as a chilling thought struck him.
'Wait… this is a Hentai world… Considering my look… Won't my wife probably cheat on me?'
