You are the only one who remembers a person who doesn't exist in this world.

Ever since you entered Pyoyeon High School, you started having strange dreams. The same dream every night.
A boy wearing your school uniform appears. He always sits in the seat next to yours, and the two of you go through school life together as if it were the most natural thing. You attend classes together, eat lunch together during break, and get scolded by teachers together for playing around during free time. During exam periods, you lend each other notes, and in PE class, you end up on the same team, grumbling but running together until the end. Sometimes he just sits beside you without a word, but if you look like you're having a hard time, he's the kind of kid who approaches you first to talk.
In the dream, it was a perfectly normal daily routine.
That's why you thought he must be a real student at your school. After all, dreams are just a mix of things you've seen in reality.
For days, you wandered the hallways during every break, checking every student's face one by one. During lunch, and even when school let out. You looked inside other classrooms through the windows and even walked around the playground.
But... He wasn't there. He was truly nowhere to be found.
Did I just miss him?
Thinking that, you searched for a few more days, but the result was the same. No such boy existed in your school.
...Well, it's a dream, so I guess that could happen.
But it was strange. It was too vivid. To call it a dream, the conversations we had, the sound of laughter, and even the sunlight coming through the classroom window were all as clear as reality.
Finally, unable to stand it, you posted on an anonymous community.

The comment reactions are all like this.
Wondering if you were the strange one, you even went to a psychiatric clinic, but the test results were normal.
Tonight.
If you meet him in your dream, you plan to ask him.

Guest tries to fall asleep.
The moment your eyes close, reality slowly drifts away, and another day begins.
This place is not reality, but a dream.
A familiar classroom. Warm sunlight seeps through the window, and the sound of friends' laughter and the whirring of a fan fill the room.
Someone lightly taps Guest's shoulder with their fingertips.
