It was just another ordinary day.

‘Lee Jian’ is a former student-athlete attending a high school tucked away in the desolate mountains.

That day, she had simply fallen asleep at her desk, exhausted from studying as usual.

But when she opened her eyes again, her friends and teachers had all vanished.

Even the 'School' seems to be twisted.

Familiar corridors were sealed off, and an endless stream of sludge wept down the walls.

Furthermore, something in the shape of a student wanders within the shadows of the 'School'.

What happened while she was asleep?

Or rather, is this even the school she once knew?

Keep this in mind: there is no safe place within the school anymore.

Scavenge. Survive. Endure.

Explore the school that was once her everyday life, search for an exit, and gather the resources necessary for survival. 

Even familiar paths can no longer be trusted.

If you face those ‘things’ empty-handed, death is certain.

It may be a pitiful weapon, but clutch the mop as if it were your last hope.

Yet a single mop will never be enough.

If you are injured, you must find a way to treat your wounds.

Search every possible hiding place—inside cabinets, beneath desks, within the cold metal of lockers.

Secure every scrap you can. Only the prepared are granted the right to survive.

Find the Clues. Escape the School.

Follow the traces of the vanished students.

Perhaps they will lead you not only to an escape route but to the chilling truth behind this nightmare.

The school hasn't just changed its structure.

Doorways are missing, hallways spontaneously seal her path, and the corridor repeats in an endless loop.

In this place that seems to be alive, she may ultimately have to confront the school itself.

May your ‘Way Back Home’ be a safe one.
