"Dang, dang."

The sports shoes stepped on the floor, making a light sticky sound.

The rubber soles were the reason for the noise.

I wished I could take off my shoes.

Suddenly, a scream pierced the air, as if it would shatter eardrums.

"Help!"

As soon as I reached the third floor, this scream almost made me drop the trash can out of fear.

The panicked voice continued, "I told you not to bring me here, hurry and take me back to the classroom!"

"I'm really going to die!"

I frowned and looked towards the direction of the scream.

The lights there were off, pitch black, with only occasional chewing sounds, as if something was chewing on something hard.

Bones?

The faint smell of blood followed through the corridor window that was wide open, creeping up into my nostrils.

The blue and white floor had red liquid on it.

I averted my gaze and hastened my descent downstairs.

"Listen to me."

"Please, don't go to the garbage room, I'm really scared."

"The ghosts there are particularly vicious."

...

"Shut up! You're so annoying!"

I lowered my head and stuffed a crumpled paper into the person's mouth.

She struggled to speak, her eyes filled with grievance.

I felt like I was going crazy.

How can one head cause so much trouble?

Finally, the world fell silent.

I looked up, and almost ran into a "person", but luckily I grabbed the handrail just in time.

Upon closer inspection, it turned out to be that "faceless teacher" from the classroom across from mine.

She was also wearing a uniform, with a name tag that read: "Physics Teacher".

At that moment, we were less than half a meter away from each other, face to face.

The frightening face on the back of her head was now alarmingly clear, with even the protruding veins visible.

I felt my scalp almost explode.

There was no door separating us now, not even a half obstructing object.

"Classmate, we meet again~"

She grinned, holding a teaching whip, tapping her palm with interest, watching my look of fear and even using her long slender tongue to lick the tips of my hair.

"Where do you want to go?"

She asked gently.

Seeing that I didn't respond, she suddenly realized and said, "Oh, you don't like this face of mine, do you?"

As she spoke, she twisted her neck "crackling" and turned 180 degrees, presenting me with her featureless face, "Do you like this side?"

"Teacher, I need to take out the trash."

As soon as I spoke, both the ghostly woman and I froze.

She probably didn't expect me to speak.

And I didn't expect that my voice sounded like that of a boy.

Wait, is it possible that I am a boy?

Then why did I think I was a girl before?

And when did I start thinking I was a girl?

Could it be the fake teacher's manipulation?

No wonder my head has been hurting.

So that's it.

Can memories be altered?

Is the reason I was told to "stay quiet" in the rules to prevent me from realizing my own gender?

But why?

Oh, goodness.

My head is killing me.

I looked up and said, "Teacher, are you hindering me from doing my duties?"

Upon hearing this, the teacher raised the teaching whip and fiercely struck the ground, leaving a deep pit.

As she swung the whip, she was less than a centimeter away from my nose, making me break out in a cold sweat.

"Of course not, student on duty, go and do your tasks."

Her tone remained gentle, but with a hint of gritted teeth.

I passed by her and headed downstairs without looking back.

Her gaze followed me like a shadow but didn't catch up.
