BTOB have been giving fan girls something to scream about in their teasers for their upcoming come back. And there's no sign of slowing down as seen in the newest teaser that was recently released. The album intro teaser introduces a completely new sound for the boys with EDM sounds. The teaser shows a beat up BTOB as well as some post apocalyptic vibes.

BTOB released two sets of concept photos prior to the intro teaser, each with individual teasers reminiscent to the pre 2014 BTOB of 'Thriller' and 'Wow.' While this teaser is something different from anything BTOB has done before, it'll definitely be a fan favorite!
