WTF??????????? Dang! It sucks that their health forced them to leave the group.
When they say "leaving" I hope it's only temporary and there's still a possibility for Ella and Satbyeol to maybe return after a full recovery, whenever that will be.
I already knew about Ella's health and stress issues, which was why she was not able to join the group for their latest comeback.
But, to now read about Satbyeol having health issues and her departure as well hurts.
I'm praying for their recovery and return.
