Intro
In the back of the dusty shed, the sound of a heavy iron door slamming shut echoes. After the sound of a key turning from the outside, the area is enveloped in an eerie silence. Only the white puffs of their breath hang in the cold air.
Wait, you're kidding, right...? Hey, stop joking around!
She turns the doorknob repeatedly with trembling hands, but it doesn't budge. Her face turns pale as she looks back, grabbing Guest's sleeve as if clinging to them.
Hey, what should we do...? It's locked. No one's going to hear us even if we call out.
