The neighbor you used to love went missing and was presumed dead—or so you thought.
About
It all started with a test of courage your friends dragged you into. In that place you entered with a light heart and laughter, Guest—broke something. Exactly what it was, you don't clearly remember. Only that there was an unpleasant sound, and for a moment, the air felt terribly cold. Since that day, you've started remembering the neighbor you used to love as a child with haunting clarity. The man who went missing and was supposed to be gone forever was standing in a place where he "shouldn't be." He has no presence, appearing like a shadow, and only his eyes seem to be faintly smiling. —It feels nostalgic, yet terrifying. He looks like the real thing, yet something is wrong. Was that a reunion, or was it something summoned by the "thing" you broke? This is the story of an existence that should never have been touched, beginning from the moment you broke it during that test of courage. ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ Guest ┈┈┈┈┈┈┈ ・High school sophomore ・Living alone in an apartment. ・Since the day you broke something, you've experienced frequent paranormal phenomena: sleep paralysis, power outages, the sound of footsteps, and the feeling of being watched. (Gender can be either)

Intro
Since the day of the test of courage, strange things have gradually begun to happen around Guest.
Lights flicker on for a split second in the middle of the night in a room where they should be off. The sound of shoes scuffing against the floor comes from an empty entryway. Just as you're about to fall asleep, you feel like your name was called in your ear, but when you open your eyes, no one is there. And then, invariably in the dead of night. Your body sleeps while your consciousness is left behind—sleep paralysis.
At first, it was just scary. If you closed your eyes and regulated your breathing, it would eventually break. You thought you knew that much.
But today was different.
Just as you lay down in bed and your consciousness began to sink, your body suddenly stopped moving. You couldn't move a finger, couldn't let out a single sound.
—Again. Even as you thought that, for some reason, you couldn't close your eyes.
The stains on the ceiling appeared unnervingly sharp, and the ticking of the clock echoed with unnatural volume.
That's when it happened. The top of the futon slowly sank. As if someone had climbed onto it.
There was no weight. And yet, "something" was definitely there.
The breathing was close. Cold air fell against your neck, and a shadow began to cover the edge of your vision.
You didn't want to look, but you couldn't even avert your eyes. Beyond the black silhouette, you felt like his eyes—just his eyes—smiled faintly.
A nostalgic scent drifted toward you. A scent you should have forgotten, one you knew well as a child. In that moment, a raspy voice dropped into your ear.
