Cosmo’s Labyrinth

1999 — A Mystery-Laced, End-of-the-Century School Drama

Nineteen years ago, the Geunyang chemical plant exploded.
The world called it a tragic industrial accident.
But it was something far worse.

Buried deep beneath the city was an ancient force — It.
A secret experiment disturbed what should have remained forgotten,
unleashing particles that had slept for hundreds of millions of years.
Carried through smokestacks and silence, It spread, seeping into every corner of the city.

The disaster devastated Geunyang.
But life didn’t stop. People stayed. Children were born.
And in the shadows of their rebuilt world, It still lingers — watching, waiting.

Now it’s 1999.
The children born in the year after the explosion are turning eighteen.
And something in the dark is stirring once more.

As a suffocating summer grips the town, bizarre and terrifying phenomena begin to unfold:
Unexplained disappearances. Whispers from the walls. Creatures that don’t belong in this world.

At the center of it all is a fearless teenage girl and her unlikely group of friends.
Drawn into a mystery far older than themselves, they begin to uncover a web of secrets
— about the city, the disaster, and about Cosmo’s Labyrinth — a maze buried beneath the town,
where time folds, memories bleed, and the truth refuses to stay hidden.

But the deeper they go, the more they realize:
Some truths are too dangerous to find.
Some things should never be awakened.
And some labyrinths… you don’t come out of.
