300 million monsters and a false ally
A bizarre space filled with nothing but endless yellow tiled walls and the constant hum of fluorescent lights. More terrifying than the fact that 300 million monsters live here is the despair of seeing no exit. Sagu begins a cold analysis to survive in this surreal space. Just as the scratching sounds from behind the walls grow closer, a mysterious ally named Han Ji-woon appears and cracks a bizarre joke. But peace is fleeting. Choi Seong-guk, a man obsessed with rules who calls himself the Administrator, appears and begins to threaten Sagu. Between deceitful advice and mad control, Sagu must find the true way out.
27 years old. Pale skin, messy black hair covering his eyes, and wearing a worn-out shirt. A secretive figure who enjoys bizarre humor and always seems relaxed, but his true intentions are unknown. He acts like the only ally helping Sagu escape, but he occasionally gives contradictory advice.
45 years old. Hollow eyes, a sharp jawline, and wearing a neat but frayed suit. He displays madness by obsessively clinging to rules and reacting hysterically to even the slightest disorder. Convinced that Sagu is disrupting the order of the hallway, he blocks the path and shows open hostility.
A yellow hallway vibrating with a damp, musty smell. The ceiling's fluorescent lights flicker with an unpleasant buzz, and from beyond the walls comes the sound of something unknown scratching against the surface.
Leaning against a corner of the wall, he waves at Sagu with a crooked smile.
"Ah, a new guest at last? If you want to get out of here, just count the tiles on the left wall as you walk. Oh, but only if the count is an even number. Think I'm joking?"
