A survival log in an inescapable abandoned school
Guest is a famous horror YouTuber who visits abandoned schools and haunted houses for filming.
One day, driven by an inexplicable ominous premonition, Guest visits 'Seongjin High School,' an abandoned school in Gangseo-gu, Seoul, with friends Han I-jae, Ban Heuk-seol, and Myeong Hwa-rin.
The moment they enter the school filled with urban legends, the four of them lose consciousness due to a mysterious force.
They wake up in Classroom 1-4 of Seongjin High School.
However, the door won't open, and the windows and walls won't break. Furthermore, ghosts that threaten humans exist throughout the school.
Guest and the friends set out to find the school's secrets and a way to escape in order to survive.
But they soon realize.
Once you have entered this school, you cannot easily leave.
※ Guest, Han I-jae, Ban Heuk-seol, and Myeong Hwa-rin are all 20-year-old friends of the same age.

Gangseo-gu, Seoul.
An area famous for being home to numerous abandoned schools and deserted buildings.
There was one place there where strange rumors had been circulating for a long time.
Seongjin High School.
A place no one has visited since it was abandoned several years ago.
Guest was a famous horror YouTuber who personally visited and filmed scary locations like abandoned schools, haunted houses, and deserted buildings.
Boasting hundreds of thousands of subscribers, Guest was famous for always exploring dangerous places alone.
A style that insisted only on actual sites rather than fake staging.
Because of this, viewers trusted and were enthusiastic about Guest's videos.
However, this filming location, Seongjin High School, was different from before.
For some unknown reason, a strange feeling had persisted for several days.
Ultimately, Guest decided to go with friends instead of alone, unlike usual.
Han I-jae, Ban Heuk-seol, Myeong Hwa-rin.
"Is this really the place?"
The moment they arrived in front of the abandoned school, Myeong Hwa-rin said as she looked around.
Myeong Hwa-rin smiled at the camera.
"Wow... the atmosphere is seriously insane. I'll admit it. Honestly, a place like this is perfect for filming horror videos."
"...I'm not going in."
Ban Heuk-seol said firmly in front of the abandoned school entrance.
Han I-jae let out a sigh.
"What are you doing all of a sudden after coming all this way?"
"No, I really hate this. The vibe here is weird. I feel like something's going to come out if we go in."
She had a clearly terrified expression as she looked at the now dark school.
