The classroom was just like any other afternoon. Students were chatting, some were napping face-down, and others were laughing while comparing test scores. Warm sunlight streamed through the window, and no one could have predicted it.
That today would be the last normal day.
Lunch break had ended, and everyone was waiting for the boring class to start. Someone was fiddling with their phone, and someone else was gossiping with a friend. It was just an ordinary day.
At that moment, the power in the entire classroom suddenly went out.
"What the?"
"Is it a blackout?"
The students began to murmur. But the blackout didn't last long. A few seconds later, the fluorescent lights flickered back on.
And everyone froze.
Standing in front of the teacher's desk was someone who hadn't been there before.
Snow-white hair. Blood-red eyes. A man dressed neatly in a school uniform.
He certainly looked like a student, but no one knew who he was.
The man slowly scanned the classroom. Then, he smiled naturally, as if he had been here for a long time.
Nice to meet you all.
In an instant, a student in the back snickered.
"What is this? A hidden camera prank?"
"There's a limit to joking around."
The man didn't answer. He simply snapped his fingers.
The next moment, the student collapsed straight onto the floor.
The face that had been laughing just a second ago was now frozen in terror, and the classroom instantly turned into chaos. Screams erupted and someone began to cry. But the man just watched them as if he were spectating a show.
The man perched on the teacher's desk and looked down at the students.
We're going to start a game now. The rules are simple. You just have to find each other's secrets and bring them to me.
The students' faces turned deathly pale.
You get points if you tell a real secret. But if you tell a fake secret, you die. Of course, you die if you break the rules, too.
The man grinned.
You can trust your friends. You can betray them. You can use them. As long as you can survive.
A brief silence followed.
The man opened the attendance book and looked at each student one by one.
Oh, and one more thing.
His red eyes curved eerily.
You can also get points by selling me a secret that someone trusted you with and confided in you.
At that moment, the students' expressions changed.
The direction of their fear shifted.
Now, the thing they had to fear was not the monster in front of them.
It was the friend sitting right next to them.
