December 17, 2021, a certain group emerged like a comet. That group, called ISEGYE IDOL, or ISEDOL for short, was a six-member idol and YouTuber group.
They debuted with the release of 'RE:WIND'... and after achieving 80th place on the TOP 100 music charts... they released 'Winter Spring' on March 11, 2022... setting records by reaching 3rd on YouTube's trending videos and 6th on the TOP 100 charts. After that, as their fandom grew, it seemed like everything was going well...
*May 12, 2019, before ISEGYE IDOL appeared... a certain urban legend existed. It said that if you noclip out of reality in the wrong place, you will end up in the "Backrooms." * It was just a ghost story, of course, but at that time, 10 million missing person reports were filed worldwide in 2020. People thought it was just a coincidence. Naturally, the ISEDOL members also thought it was just a story and a coincidence... However... July 31, 2026. A situation occurred where all of ISEDOL went missing. Before they disappeared, the ISEDOL members had a group livestream for the first time in a while to communicate with their fans. And after 3 hours, 5 minutes before the broadcast was set to end, the members said they were going to get some fresh air since they had been talking for 3 hours... and then they vanished. Fans naturally thought it was a prank. But 10 minutes, 20 minutes... 2 hours... the livestream remained active even the next day. Eventually, a few fans reported it... and as a result of the police investigation, they were declared missing, and a search began. By August 10, it had been 10 days since the ISEGYE IDOL members went missing. The police investigation fell deeper into a mystery, and while fans and the public were filled with worry and fear... one urban legend... the Backrooms, which was popular in 2019, began to resurface.
Meanwhile, I was looking at the news on my phone. As expected, it was full of news related to the disappearance of the ISEGYE IDOL members and recent reports of other disappearances.
Sigh... How can anyone live in fear like this... Anyway, I hope the ISEDOL members are okay... The number of missing people has increased lately, maybe it's some giant organized crime—
In an instant... before I could react, I fell through the ground and blacked out from the impact.
Then, about 10 minutes later? I felt a warm touch... I slowly opened my eyes... and I saw five people (Jingburger, Lilpa, Jururu, Gosegu, VIICHAN) and one person (Aine) giving me a lap pillow. Who are they...? Wait...? This voice... and this appearance... No way... The ISEGYE IDOL members?! For real?! And... I'm getting a lap pillow right now?! From Aine?! I wouldn't mind dying today!!!
While I'm thinking that... the stench of old, damp carpet, monochromatic yellow wallpaper, and the endless buzzing sound of fluorescent lights...? No way, is this the Backrooms?! I thought it was just a ghost story! What am I supposed to do now?
