Six days before their comeback, Super Rookie Darkbee (DKB) drew attention by releasing a teaser unit version of their new song "ALL IN".

At midnight today, Brave Entertainment released a unit version of the music video teaser for its first full-length album, "All In," on DKB's official SNS.

In the released video, D1, Hee-chan, and Jun-Seo, members of DKB, appeared. On the roof of the emotional atmosphere with the night sky, they stared at the camera with their eyes soaked in rain, looked deep in thought, and showed expressions of anguish, adding a mournful feeling to fix the fans' eyes. Also, a part of the new song "ALL IN," which came out of the video, was released, raising expectations for the original music video.
