Previously, the group unleashed their ambition in the 'JUST BURN' trailer, followed by individual teasers of member DY.

On June 17 at midnight KST, the rookie boy group unveiled the teaser images of the second member, Bain. Bain is ready to be engulfed in flames as he intently gazes into the camera sitting in front of a fiery red backdrop.
