Flat on the floor, I stared blankly up at the text. And the very first thought that came to mind was a single one.
‘Am I mentally ill?’
I picked up my phone, nearly crawling. My hands shook so badly I couldn’t unlock it on the first try. After fumbling several times, I finally opened the search bar and typed in words.
Schizophrenia early symptoms
Hallucination floating text
Seeing system window
Visual hallucination mental illness
Mental illness test
Window floating in air
Search results flooded out.
Schizophrenia, visual hallucinations, delusions, stress symptoms, dissociation, derealization.
I scanned the screen, then looked back at the window floating before my eyes.
‘But it’s too vivid?’
It didn’t feel like it was following me when I moved my head. It felt like it was genuinely overlaid on my vision.
“...I’m too healthy to be mentally ill.”
Now that I’d said it out loud, it was fucking baseless nonsense.
Healthy people aren’t immune to mental illness either.
But I had really thought so. I worked fairly steadily, ate well, slept well, and even exercised sometimes.
I didn’t think I was broken enough to have blue windows floating in the air, at least...
The problem was, that thing was hovering there right now.
I turned my gaze back to the window.
[Confirm]
I stopped, hand reaching out to press it.
‘Wait, no? You don’t press things like this with your hand—don’t they react when you just think about pressing?’
The moment I thought that, the window changed.
“Ooh.”
Goosebumps rose.
The next screen was even shorter and simpler.
[Customization]
I swallowed.
‘Confirm.’
The moment I made up my mind to truly press it, the screen changed immediately.
[Body]
[Proportion]
[Optimization]
It was like a game character creation window. But the screen was so cold and dry that it felt strangely off.
I hesitated for a moment, then raised the height value by just a tiny bit.
At that moment, a tingling sensation spread throughout my entire body.
“What!...What the hell!”
A sensation like a very faint electric current sweeping from the soles of my feet to the top of my head. My spine seemed to stretch slightly from the inside. It wasn’t pain, but it was bizarre and unfamiliar.
I held my breath and adjusted my shoulder area a bit as well.
I felt my collarbones, back, and shoulder joints being pushed slightly outward before settling back into place.
When I ran my hand over my shoulder, I could feel the changed frame.
“...Is this real?”
My heart sped up again.
Then a button at the bottom caught my eye.
[Optimization]
[Changes you to the user's desired ideal appearance]
I stared at that sentence for a long time.
‘My desired ideal appearance...’
It was a suspicious sentence, but it was fucking enticing.
As if bewitched, I reached toward the button, then stopped.
This system reacted faster to thought than to touch.
The moment I recalled that.
[Proceeding with optimization.]
“Ugh...crazy.”
Something began moving in earnest inside my body.
It felt like countless tiny hands were crawling beneath my skin all at once. Muscles pulled slightly, bones slowly shifted angles, and joints settled back together in natural directions.
My back straightened, my neck aligned, and my shoulders spread out nicely.
Inefficient parts throughout my body were cut away, rearranged into the best form I had imagined.
The sensation of my jaw, cheekbones, and the area around my eyes being smoothed out from the inside was vivid.
I got up almost staggering, took off my top and threw it aside. Then I went to the mirror.
And stopped.
The person standing in the mirror was me. But he was far more improved than the me I remembered.
Everything started with his posture. His shoulders were naturally wider, his neckline tidied, his upper body frame much larger and broader than before. His waist was clean without a trace of flab, and his chest and abs showed definition even without flexing.
I moved closer to the mirror.
My face was visible.
My skin texture had changed. The darkness around my eyes was gone, my jawline had sharpened, and the overall proportions were subtly improved. It wasn’t a completely different face like plastic surgery.
‘Fuck, who are you!’
My gaze, which had been blankly staring at my own face, slowly moved downward.
The moment I checked below, my thoughts ground to a halt.
“......Huh?”
My lower body had completely changed as well.
It wasn’t just a little different. Its very presence was different. Standing still felt awkward, as if something absurd was attached to my lower body.
I froze on the spot.
“Oh, my God.”
It was a change you’d only see in dreams, but the sensation was overly vivid.
I lowered my pants with a blank face.
The length looked to be nearly 20 centimeters, and the girth looked more than double what it was before.
‘Huh...’
Wondering if this was reality, I reached out.
Tap.
The moment it touched my fingertips, my breath caught in my throat.
‘Oh, Lord.’
A heavy heat and intimidating form were tangible in my hand. This couldn’t possibly be a hallucination.
It took several seconds to pull my hand away.
“Wow...”
I could tell it had improved. But that was precisely what scared me.
Because it had changed too perfectly in the direction I wanted, into the ideal of desire I had imagined.
The me in the mirror was unfamiliar, yet strangely satisfying. That was the creepiest part.
Only after a long while did my mouth finally open.
“Good God...what is this?”
And at that moment.
Beyond the mirror, blue text quietly rose in the center of my vision.
[Dimensional Archive]
□ □ □
The me in the mirror was still me.
I was myself, yet clearly different from the me of just moments ago.
An upper body trimmed into an inverted triangle. A face that was visibly more handsome. And an alpha-male-level presence that shattered common sense every time I lowered my gaze.
“......”
I squeezed my eyes shut and opened them again.
It didn’t disappear.
[Dimensional Archive]
Below it, a new window popped out like spam mail.
[Privilege Grant Notification]
[Biological Adaptation Lv.1 (00.1%)]
[Aging Suppression Lv.1 (00.1%)]
[Mental Protection Lv.1 (00.1%)]
[Confirm]
I stared at it blankly, then let out a hollow laugh in disbelief.
“Mental protection?”
Seems like it’s already too late.
‘Is that the reason I’m still sane?’
The moment that thought crossed my mind, the confirm button was pressed.
“Ah, fuck!”
That startled me.
My heart dropped.
The pop-up disappeared, and the basic screen hidden behind it slowly opened.
It wasn’t overly flashy, nor did it shine like a game screen. Rather, it was so bland it was almost unpleasant.
────────────────

────────────────
I stopped at the second line.
‘Reality : Earth-0300.’
“...What?”
I blinked and looked again. The sentence remained the same.
The reality I had been living in until now wasn’t simply reality; inside something’s window, it was number 0300.
The moment that thought occurred, a chill ran down my spine.
And below that, the time was obediently counting down by the second.
[Next refresh in : 23:57:30]
[Next refresh in : 23:57:29]
[Next refresh in : 23:57:28]
My room was still quiet.
The sound of the refrigerator running, the sound of a car passing somewhere outside the window.
The world was perfectly fine, yet that thing was floating in my vision.
I picked up my phone, then set it back down.
‘No, what good is searching when a status window is floating in the air right now?’
I bit my lower lip slightly and turned my gaze to the status window.
‘Might as well see this through since I’m already crazy.’
The moment I thought that, I felt something in my head click slightly into place.
“Let’s start with the structure.”
I pressed [Ability].
[Passive] [Active] [Replicate] [Optimization]
Almost reflexively, I pressed [Passive]. Inside the passive section were the familiar yet foreign letters I had seen earlier.
[Passive]
[Biological Adaptation Lv.1 (00.1%)]
[Aging Suppression Lv.1 (00.1%)]
[Mental Protection Lv.1 (00.1%)]
I read them slowly, one line at a time.
Biological Adaptation.
Aging Suppression.
Mental Protection.
All three sounded plausible. So plausible they felt like a cheap game.
The guy who had been searching for mental illnesses upon seeing a floating window just moments ago was now calmly reading passive descriptions.
It was scary. But I hadn’t completely broken down.
What mattered was one thing.
‘I’m maintaining normal thought right now!’
I checked the active side too, but there wasn’t much to see.
[No registered usable items]
A single short sentence was all there was.
I pressed Replicate too.
There was nothing.
[No recorded targets]
Optimization, perhaps because I’d already used it once just now, had only a single short sentence at the bottom of the screen.
[Appearance optimization applied once]
I immediately went back and pressed [Log].

I froze solid.
It was recorded by the second. Even the order was exact.
First connection, user recognition, base reality registration, privilege grant.
This was closer to a ‘log’ than a hallucination. More precisely, it was a recording device belonging to something that had already registered me as a user.
Suddenly, goosebumps covered my entire body.
There had been nothing like my permission. ‘Dimensional Archive’ had already recognized me, put a number on the reality I lived in, and very nicely taken apart and reassembled my body. And it recorded all of that as if it were only natural.
I slowly breathed in, then out.
“Hoooooo...”
Still, the rules were starting to become visible bit by bit. For better or worse, this was far more precise than a hallucination running rampant.
I shifted my gaze to the last tab.
[Dimension]
I hesitated for a moment.
This was a word that really seemed like something would open.
I swallowed dryly.
“Ah...no way.”
And I pressed it. The screen changed.
[Dimension List] [Saved Dimensions]
Almost reflexively, I pressed [Dimension List].
Nine dimension names rose very simply. No explanations, no friendly guidance. There were only names.
[Dimension List]
Human Ranch-4614
Glass Beach-3227
Flesh Scripture Corridor-3721
Atlantis-1334
Dark Universe Livestock Farm-9648
Astrania-1337
Nameless-8224
Earth-0382
Paradise Exile Zone-6915
I slowly scanned the list from top to bottom.
Glass Beach.
Flesh Scripture Corridor.
Atlantis.
Dark Universe Livestock Farm.
‘These don’t look normal just from the names?’
And around the lower middle, my gaze stopped.
Earth-0382.
My reality was Earth-0300, yet Earth-0382 was on the list.
‘Does that mean it’s not the same Earth...’
That fact was strangely chilling.
Because it meant the reality I had lived in was merely one of countless worlds inside this thing.
And above that.
Astrania-1337.
Strangely, that name caught my eye.
But before that, what had grabbed and held my gaze was the very top.
Human Ranch-4614.
I stared at those words for a long time.
Ranch. Not ‘people,’ but ‘humans.’
Just the name made me feel dirty.
At that moment, one very short sentence appeared below the list.
[Movement executed after will is confirmed]
I closed my mouth. My fingertips grew cold again.
“Fuck...what is this.”
My room was still quiet.
The me in the mirror stood with an improved face, and the clothes I’d taken off were crumpled on the bed.
The world was so ordinary, yet words like Human Ranch were floating in my vision.
I stood before the dimension list, unable to move for a while.
It seemed like it wouldn’t be a normal world. But strangely, I felt like that was the first thing I should press.
Very slowly, truly slowly, I fixed my gaze on the topmost name.
Human Ranch-4614.
