Crayon Pop member ChoA has taken to Twitter to announce that she will be one of the members of her group’s new subunit project.

Chrome Entertainment, the talent agency that represents the girl group, has announced that the subunit is set to release material sometime in October.

The star posted a photograph of herself with her hand cupped into the shape of the letter C (perhaps short for the first letter of her name).

She wrote, “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!”

Chrome Entertainment has also recently revealed that Crayon Pop’s full-group comeback has been pushed back, as final touches are still being put on the new material. A Crayon Pop studio album had originally been slated for a September release, but it seems that the new album will drop after the new subunit has finished promoting its release.
