so title says it all. So I want to write a full on story about a girl group rookie but I haven't decided on which one yet.
Plot wise, I've narrowed it down to this three ; 
- elite group of girls recruits new member
- queen bee dead friends suspected
- main character tries to open a club/group/event forced to work with a bunch of strangers

I'm planning to write all three at some point, but for now y main problem are choosing the girls to cast in the story. I prefer girl group rookies to those who have been on the scene longer. I figured I get others opinions on which group might fit the story plot wise I guess.

I'm familiar with
- Red Velvet
- TWICE
- IOI
- Lovelyz
- OH MY GIRL
- APRIL
- GFriend
- CLC
- MAMAMOO

I'm considering other groups as well, but I might have to look them up to write them. I think I left out a few groups off the list.
What do you think?
