So there's going to be a Crayon Pop sub-unit and today 50% of it was revealed when Choa said:
“Ta-da! I can reveal that the first member of the Crayon Pop subunit is me, ChoA! We have been working very hard on the new subunit album. Please expect a lot! Who do you think the next member will be? That will be revealed tomorrow!”While I'm legally obligated to keep a secret until tomorrow when it's officially revealed I can give you this clue. Her name starts with 'W' and ends in 'Y'. Well, now that's official I can tell you it's way Way. In case you couldn't figure it out from my hint.
I actually hope it's Soyul to be honest.
