The agency Brave Entertainment released DKB's second music video teaser on its official SNS channel on Oct. 21.

DKB's new song "Work Hard" is a very attractive hip-hop R&B song with the lyrics "I Work," which is repeatedly heard in the chorus with the 808 sound and pluck sauce, and contains the message that they will work hard for a wonderful future with their loved ones.

DKB's third mini-album [GROWTH] is scheduled to be released at 6 p.m. on Oct. 26.
