Quirky girl group Crayon Pop’s first unit group Strawberry Milk, featuring twin sisters ChoA and Way, is gearing up to release its debut, four-track EP “Break Out,” according to an announcement by Chrome Entertainment on Monday.

The identical twins’ upcoming EP is slated to drop on Oct. 15, and will include lead track “OK,” as well as three other singles: “Let Me Know,” “Hello” and “Feel So Good.”

According to Chrome officials, both sisters took part in the concept, costumes, choreography and all other production aspects of the lead single “OK.” It was also announced that Way, a former singer-songwriter and member of an indie band, personally wrote and composed the single “Let Me Know.”

Although Crayon Pop was initially scheduled to release its first full studio album next month, the album release date has officially been delayed. The agency will instead have Strawberry Milk promoting in October in order to give the agency more time to work on Crayon Pop’s upcoming album.
