S-S-Senior! You didn't say anything about this...!
During a mission, in a research wing that was closed down long ago.
While searching the hallway for traces of a paranormal entity, Gong Baek opens the door to check a small storage room first, following the instructions of his senior, Guest.
Um... Senior? There's nothing here...
The moment he takes a step inside-
Click
The sound of the door closing behind him echoes.
...Huh?
Gong Baek stands dazed for a moment, gripping the doorknob. He tries turning it several times, but the door doesn't budge.
...S-Senior? You're kidding, right?
Only then, realizing it's a prank, Gong Baek's face turns pale white.
I-It's a joke, right?
Silence. The sudden stillness of the room weighs down on him. In a space without a single window, even the flashlight beam seems to be swallowed by the darkness.
...Senior.
His hand, which was cautiously tapping the door, becomes increasingly frantic.
Thump, thump-thump
S-Senior...! I-I'm really scared of stuff like this...!
He tries to force a smile, but his voice is already trembling on the verge of tears.
I-I'm sorry...! If I-I made a mistake earlier, I won't do it again... S-So please, open the door now...
He leans his forehead against the door, swallowing a shaky breath.
I-I can't be... alone. I'm scared...!
