The first time I realized something was wrong with this world… was during a company first-aid training session.
The instructor pointed at the human body model and said:
“Remember, human blood is blue. It only gradually turns red after it comes into contact with oxygen in the air.”
At first, I thought he was joking.
But when I saw everyone else nodding seriously and writing it down, I couldn’t help but raise my hand.
“Excuse me, sir. Did you make a mistake? Blood is always red.”
The instructor and all my colleagues turned to look at me like I was a freak.
He frowned, flipped open the training manual, and showed it to me. On the white page with black text, it clearly stated:
“Blood is blue.”
I was stunned into silence.
I quickly pulled out my phone and searched it. The results were exactly the same as what was in the manual.
My colleague Jessica quietly tugged at my sleeve and whispered with a worried look:
“Have you been overworking yourself lately? How could you forget something so basic?”
I didn’t know how to answer her.
Under everyone’s strange stares, I forced a smile and said I was just joking.
As soon as the training ended, I rushed straight to the bathroom.
Gritting my teeth, I used a safety pin to prick the tip of my finger.
Bright red blood immediately welled up.
I finally breathed a sigh of relief.
My memory wasn’t wrong.
I still didn’t understand what was happening… but these people were clearly playing a sick, elaborate prank on me.
Just as I was about to leave, I overheard two colleagues talking outside.
“Sarah was so funny today, claiming that blood is always red.”
“Yeah. What a coincidence — my gums are bleeding right now. I almost wanted to call her over to see.”
I secretly peeked through the gap in the bathroom stall door.
My colleague smiled in front of the mirror, using a tissue to wipe the blood from the corner of her mouth.
On her pale white teeth…
A line of blue blood was slowly turning red.
This was probably the first time I had ever seen blue blood on a human being.
I was so horrified that I instinctively covered my mouth, not daring to make a sound.
They weren’t wrong.
I wasn’t wrong either.
So… where exactly was the mistake?
I waited a long time after they left, making sure the bathroom was empty, before quietly slipping out.
As I walked through the office, everything that should have felt familiar now felt terrifyingly alien.
Because I had realized I was different from them.
I feared I was an outsider — a freak in this world.
Back at my desk, my direct supervisor, Mr. Thompson, quickly called me into his office.
“I heard you haven’t been resting well lately. Is the pressure getting to you?”
I knew what he was implying, but I didn’t have the courage to admit the truth.
Deep down, I felt that being seen as “different” was not a good thing.
I brushed it off with a few vague words, insisting it was just a joke and that I didn’t expect everyone to take it seriously.
Thankfully, Mr. Thompson didn’t press further. He just smiled politely and told me to take better care of myself.
That night, I locked all the windows and the front door, drew the curtains, lit a scented candle, and went to bed early.
I hoped this was all just a dream, my own imagination. I hoped that when I woke up, everything would return to the world I remembered.
But I stayed awake until 3 a.m., becoming more and more certain that I wasn’t the one with the problem.
So what the hell was going on?
I got out of bed, opened my laptop, and searched about blood again. The results were the same as during the day.
No — it wasn’t just the same. I made even more shocking discoveries.
The introduction for the Empire State Building said it was a symbolic landmark in downtown Manhattan, completed long before the 2008 Olympics.
I searched for “One World Trade Center.” The images that appeared were three strange buildings I had never seen before, called the “Financial Triad Towers.”
I searched for the “Hudson River,” and the result showed “the river flowing through Newark.”
I slammed the laptop shut, breathing heavily.
This was insane.
At the same time, I confirmed that this world was definitely not the one I was familiar with.
However, I didn’t say anything out loud.
When I posted online expressing doubts about all of this, I quickly received two replies:
[OP should go see a doctor.]
[OP didn’t escape from somewhere, did they?]
The second reply immediately served as a warning.
I was not from this world. To me, this might be more than just shocking.
If I recklessly exposed myself, it could bring real danger.
So I immediately deleted the post and began disguising myself in daily life.
I tried hard to act like a “normal” person.
At the same time, I carefully observed everything in this world.
Fortunately, aside from a few basic facts that differed from my memory, I hadn’t yet found anything that seriously affected my daily life.
This made me breathe a little easier. Maybe my earlier worries were unnecessary.
But three days later, the first-aid instructor returned to our company.
He handed out a test sheet to everyone, instructing us not to discuss and to submit it directly once finished. He said it was to evaluate the training results.
At first, I didn’t think much of it — until a long-time employee muttered:
“We’ve had this training for years, but this is the first time we’ve had to take a test.”
My heart skipped a beat.
Was this aimed at me?
I secretly glanced at my colleague’s paper.
Cold sweat instantly broke out on my back.
Everyone else’s questions were standard first-aid knowledge.
Mine were different.
The first question: What color is human blood?
The second question: What color is a newborn baby’s hair when they are born?..
I quickly realized I was being watched.
I didn’t know what this meant, but my instincts told me it was nothing good.
Suppressing the trembling in my fingers, I calmly wrote down “blue” and “white.”
When I handed in the test, the instructor looked at me meaningfully but said nothing.
I wasn’t sure if I had passed or not, but I knew that from now on, I had to be even more careful with every single moment.
The next day at lunch, I went with a few colleagues to a new restaurant near the office.
Everything that had happened recently made me unconsciously more sensitive to my surroundings.
That’s why I quickly noticed a man in a gray coat sitting alone at a table diagonally behind us.
I had a vague feeling I had seen him on the subway that morning.
Right now, there was a single meal in front of him, but he wasn’t touching it. He kept staring at his phone.
I picked up my own phone and used the screen as a mirror, pretending to touch up my makeup while watching him.
Within less than a minute, he looked up three times — each time “accidentally” glancing at me in an eerily precise way.
I knew it in my gut. He was here for me.
I didn’t confront him. I pretended not to notice, finished eating, and left with my colleagues.
In the afternoon, I made several excuses to go down to the convenience store on the ground floor. As expected, I “coincidentally” ran into him each time.
When it was time to leave work, I stood at the entrance of the office building, hesitating.
Should I take a taxi home to shake him off?
Should I follow my usual route and accept his “coincidental” company?
Or should I walk straight up and ask him what the hell he wanted?
I wasn’t fearless, but deep down, I desperately wanted to understand what was happening.
So I made a bold decision.
Instead of taking the main road home as usual, I turned into the narrow alleys of the old neighborhood where I used to rent an apartment.
After turning at three intersections, I slipped into a convenience store, ordered some hot food, and openly sat by the floor-to-ceiling window to wait.
The path leading down from the store was a dead-end alley.
The only resident there was my former landlord.
So I just needed to wait for the man in the gray coat to turn back — and I would have him cornered.
No matter what excuse he gave, there would be no way to explain why he was following me.
So far, neither the instructor nor the man in the gray coat had confronted me directly, which meant they still didn’t want to do anything to me yet.
That was my biggest trump card — I was still safe.
But after the man in the gray coat walked past the store window, I waited for a long time… and he never came back.
The sky grew dark. I stood outside the convenience store in surprise, staring down the right side of the alley.
The dead-end alley was quiet and empty. Only the streetlights had automatically turned on, casting their glow on the weathered stone walls and the ground.
The man in the gray coat had vanished, as if he had never existed.
At that moment, I once again felt a chill run down my spine.
