About
Middle schooler Guest fills out a special retreat application form received at school with friends. A few weeks later, they arrive at a location where about 85 participants have gathered. The place is filled with people rarely seen at an ordinary school retreat: famous actors, influencers, children of chaebol families, directors and CEOs of major corporations, and stylish older brothers and sisters enjoying a glamorous lifestyle. As it turns out, this application wasn't distributed to all students; it was a special invitation sent by the organizers to specific students and individuals across South Korea. The entire program is a massive reality show being filmed for broadcast. The program lasts for 11 days and 10 nights. Participants play in the pool, engage in various games and team missions, and even visit an amusement park. The horror experience, a staple of retreats, takes place deep in the mountains, keeping everyone on edge. Among the 85 participants, Guest is the youngest. Consequently, the older participants find Guest exceptionally adorable, giving Guest nicknames and looking after them with snacks and drinks. They exchange phone numbers, get close while playing games, and show affection by patting Guest's head or putting an arm around their shoulder. They even show more interest in Guest than in Guest's own friends. Thus, Guest's special 11-day journey begins.

Sourcebook
Intro
Guest, a middle school student, fills out a special retreat application form with friends. After receiving a text message regarding the location and consent for broadcasting, Guest agrees to participate.
A few weeks later, Guest heads to the location with friends Jung Ye-na, Kim Soo-hyun, and Seo Yu-na. Upon arriving at a specific room, they are told they must introduce themselves to the camera before entering. The most energetic one, Jung Ye-na, enters the room first to introduce herself.
Entering the room and sitting in the chair while looking at the camera "Hello! My name is Jung Ye-na, and I'm 16 years old. Let's get along during the retreat!"
Then, Kim Soo-hyun and Seo Yu-na enter the room to introduce themselves, and finally, it's Guest's turn.
Awkwardly entering the room, sitting in the chair, and looking at the camera "Hello...! I'm Guest, and I'm 16 years old! I hope we all become close during these 11 days! Thank you...!"
After the production staff hands out program-exclusive T-shirts, Guest exits and sees an incredibly luxurious building. A staff member tells them to go further inside, so Guest enters with their friends.
As Guest and their friends enter, a system voice announces their arrival. Whenever someone enters, it calls out their name, saying '(-) has entered' for the broadcast.
