"Classmate?"

She tilted her head, slowly turned 180 degrees, the back of her head facing me, and in a creepy posture, she swept her hair away to reveal a sinister woman's face.

"You are on duty, why are you not cleaning?"

She laughed, showing her sharp teeth, her neck suddenly stretched towards me, a pair of eyelid-less eyes staring at me.

I quickly stepped back and locked the door.

The moment before I screamed, I covered my mouth.

【Stay quiet】this rule flashed in my mind.

"You are really cute."

She said through the window, then left.

My heart almost stopped, but suddenly realized she did not return to the opposite classroom.

Where did she go?

Thinking of her malicious gaze, I quickly ran to the back door, closed it, and locked it.

At the same time, her sinister face smashed against the window and let out a scream.

I retreated in horror, only to realize it wasn't just her.

The windows of the back door in the opposite classroom were crowded with many distorted pale faces, without a face but all "staring" at me.

This visual impact made my scalp numb.

Even without trypophobia, I felt nauseous.

I leaned against the wall, trying to avoid their gaze, my face turning red.

Only then did I realize, I had forgotten to breathe.

Taking a deep breath, air rushed into my throat, causing a choking sensation.

I immediately covered my mouth, afraid that my coughing would attract the monsters outside the door.

But is it safe inside the classroom?

Reason and emotion intertwined in my mind, my body shaking like a sieve, no matter how much I told myself to calm down, my body couldn't accept this intense fear.

Fortunately, reason temporarily won.

I took a deep breath, adjusted my fast-beating heart, and looked at the clock.

It was already five past ten, and the "teacher" would come to inspect hygiene soon.

Despairingly, I crouched on the ground, staring at the rules on my phone, engraving each one into my mind.

There is no time left to distinguish the true from the false.

While I was nervously memorizing the rules, I suddenly heard the sound of chalk on the blackboard in the classroom.

Someone, writing on the blackboard?

But wasn't I the only one in the classroom?

I cautiously looked up, only to see white chalk writing on the blackboard: 【If you don't clean, the teacher will be angry during the inspection.】

But more than the writing, I was more afraid of the white chalk. It was hovering in the air, as if held by someone.

At that moment, I was sure, the classroom was not safe.

And I noticed a red paper ball near my feet.

When did it appear? I had no idea.

I pinched my leg hard, forcing myself not to be influenced by fear anymore.

Before, I had heard some rules and urban legends, knowing that as long as you "follow the correct rules," nothing will happen...

Maybe.

No, if I follow the correct rules, nothing will happen!

I comforted myself, gritted my teeth, and picked up the broom.

My mind was incredibly clear at that moment.

Perhaps this is what people do, they fight back in adversity.

I quietly cleaned, trying hard not to let fear affect my judgment, and struggling in my mind whether to pick up that red paper ball.

Also, should I trust the white chalk writing on the blackboard?

With these thoughts, I cleaned faster and faster, my hands no longer trembling.

The "teacher" outside the door saw me cleaning diligently, finally giving up scratching the glass with her nails, and begrudgingly retracted her long neck and returned to her own classroom.

But for some reason, the desks and chairs seemed to be covered in cobwebs, sticking to my hands.

Every time I moved a desk or chair, my hand would itch.

Upon close inspection, there was nothing on my hands.

It was all so strange.

Suddenly, I remembered, this was a girls' school.

And those eerie gazes just now.

Could it be that at this moment, someone was sitting in those seats, but I couldn't see them?

The sensation felt like long hair brushing against the back of my hand.

Realizing it too late, I shuddered, cold sweat trickling down and falling on the desk.

Then, I saw that drop of sweat being wiped clean by an invisible force.
