The abandoned school sat as if submerged in a mountain valley. At the end of a winding path, an iron gate, seemingly consumed by trees, was half-rotted, with a "No Entry" sign hanging upside down and swaying.

As you climb over the wall and step inside, a massive silence blankets everything. Not a single insect chirps; even the wind seems to hold its breath.

The grass has grown knee-high, and the playground is filled with rusted pull-up bars and collapsed seesaws.

Step, step, step.

You continue walking into such a place.

As you pass the school gates and enter the building, the smell of mold and damp dust seeps deep into your lungs.

The hallways are plunged into darkness as if the lights went out long ago, and the walls are scattered with indelible palm prints and chaotic graffiti that looks as if it were scratched by someone's fingernails.

When you arrive in front of the girls' restroom, a strange energy begins to permeate the air.

The temperature drops suddenly, and every breath feels heavy and damp, as if you're breathing through a wet cloth.

Even though the floor in front of the door isn't wet—

Drip... drip...

The sound of wet footsteps doesn't stop. The sound echoes, without fail, from beneath the gap of the third stall door.

Small handprints are layered and smeared over the restroom door, and one of them looks like a very vivid bloodstain.

And, on the wall, a message is written, though it's unclear who left it.
