Not all idol groups in this fanfiction will be complete. I will be writing below which members are NOT in their respective groups. this means that all people mentioned down below are Seongnam locals. I will update the list as more characters are added.

NCT: Yuta, Kun, Sicheng, Ten, Jungwoo, Jeno, Renjun, Doyoung (was a trainee but left before debut)

Red Velvet: Irene 

Loona: Jinsoul, Chuu

ACE: none of them are idols 

IZ*ONE: Nako

Pentagon: Yuto

Soojin, Jaemin, and Yoongi are all Seongnam born idols. Soojin and Yoongi both lie about where they are from as Seongnam kids have a bad rep about them and they both became idols for different reasons. Jaemin lied about where he was from so people would not get suspicious as he asked about Doyoung and he became an idol solely to find out about Doyoung.
