The teaser is also indicated to be 19+ rated in the upper corner at the start of the video, warning fans there lies some sexy content ahead. But don't worry, it's pretty mild. We see a group of female dancers showing off some moves then it flashes to a party scene where we see even more girls.�

Although we're left wondering what all the dancing girls have to do with the boys' new concept, the video teaser still keeps in theme with BTOB's comeback with the wheel rims and cars in the background.

Check it out above as we await even more clues about their return!
