Instiz: Withdrawals and additions of a 9-member girl group with only one debut member remaining
- At this rate, the problem is the company
- Ugh... I miss Sera ㅠㅠ Minha-ya...
- Hyemi must be feeling strange
- I've never seen a successful girl group after so many member changes. Same with After School... I think they should've just continued with less members without adding more members
- It's hard to not get popular with Nine Muses members. It's weird.
