"Boom boom boom."

The door was knocked on, startling me.

I looked up and saw the head teacher standing at the door, wearing a uniform and a badge that read "Head Teacher."

"Why is the door still locked when you're supposed to be cleaning?"

I swallowed nervously, looked at the clock, it was ten fifteen.

Not time yet.

【The teacher won't come for an early inspection.】

This rule had been repeated many times, I was very clear about it, and my gaze unconsciously turned to the classroom opposite.

There was no one there, and the lights were off.

The mist outside had dispersed, and the bustling chatter could be heard from downstairs, everything was back to normal.

It was as if those moments ago were just illusions.

"Alright, it's too late to clean up, go back to the dormitory and rest."

The teacher smiled and said helplessly to me, "You've worked hard today."

I blinked, my mind was in a daze for a second.

There were countless small, seductive voices in my ears: "Open the door, open the door and leave here."

Those voices seemed to drill directly into my brain, controlling my actions.

But her smile was so beautiful.

So gentle, so warm.

I took a step forward, involuntarily walking towards her.

My eyes were filled with her curved eyebrows, high nose, and plump red lips.

So beautiful.

Just as I reached for the door lock, my hand stopped involuntarily.

The fragmented voices grew louder, but I hesitated a bit.

Why was I hesitating?

Wait, does the school have this teacher?

Realizing this, my hand felt like it had been burned by the lock and I quickly pulled it back.

I suddenly saw the light.

This ghost, she could actually enchant people.

It was close...

A huge panic hit me.

I looked at the head teacher outside the window, she still looked so beautiful, her eyes seemed to have shards of light, constantly tempting me.

I slapped myself hard, turned around without looking at her again, continued to clean up, and disposed of the garbage in the trash can.

Because I didn't know how to change the situation, I could only choose to continue to do what the duty student should do.

Who knew, the garbage can suddenly made a sound: "Don't open the door under any circumstances."

I was stunned, thinking of the fourth rule.

【If you find a head in the garbage can, don't believe its words.】

I was numb.

Trembling, I looked inside, and sure enough, there was a head.

A girl's head, with a crack in the neck.

She looked just like a living person, but she scared me enough to fall to the ground.

I looked at the garbage can in horror.

The head in the bucket seemed unconscious, muttering to itself: "You need to pick up that red paper ball, inside it has a way to escape."

I clenched my fists, didn't know whether to believe the rule or this eerie head.

The rule told me not to believe her words, but she told me not to open the door.

Did that mean, this fourth rule was fake? Could I trust her?

"Don't pick it up! You dead head, don't grab my food!"

The monster outside heard the head speaking and began to roar.

Its tongue lashed against the glass one by one.

Soon, there was a cracking sound.

The glass was about to break!

"Quickly pick it up! It's been half the time now, once the glass breaks, you're done for."

The head urged anxiously.

I looked at her, feeling as if I were being grilled over fire.

Should I trust her?

Were these two ghosts playing me together?

"Click!"

There was another cracking sound on the glass, and at that moment, everything seemed to slow down.

Only my brain was working at lightning speed.

The next moment, I picked up the red paper ball, and the knocking on the door stopped.

The "teacher" outside, who was unrecognizable, looked greedy and sinisterly at me, suddenly grinned and slowly stepped back into the darkness.

I tightly held onto the red paper ball, not knowing why she was smiling.

What was so funny?

Did I break a rule?

Or was she deliberately deceiving me?

I shook my hand, trembling, trying to analyze the appearance of these monsters a few times.

The first time, I stepped out of the classroom.

The second time, I didn't clean up or lock the door.

The third time, I didn't pick up the red paper ball.

Did that mean, these times, I broke the rules?

But it was also true that every time I broke a rule, a monster appeared.

When I picked up the red paper ball, the monster left.

Did that mean, 【Don't pick up the red paper ball, they will find you, don't trust the words on it】this rule was fake?

"What are you hesitating for? I'm speechless, quickly open it."

The head urged, feeling even more anxious than me.

I glanced at her, she had a melon-seed face, bangs, and round eyes.

She seemed harmless.

I lowered my head, slowly opened the paper ball, there was only one sentence on it: "After throwing out the garbage, leave the classroom, don't wait for the teacher to inspect."

"What does it say?"

The head asked.

I looked at her, rolled the paper back into a ball, and threw it in the trash can.

"Oh, come on, I told you to keep quiet, not that you couldn't talk, are you trying to make me nervous?"

The head said helplessly.

I pressed my lips together, didn't respond, took a deep breath, and opened the door.

"Click!"

The lock opened.

In this silent corridor, a crisp echo rang out, as if it was a signal.

Telling "them" that the "food" had left the room.
