Following an R-rated teaser image posted earlier, Nine Muses released a still-cut footage of their 'lingerie look' music video of "Wild."

On May 1, the management company of Nine Muses announced their official comeback date and outlined their upcoming schedule for album promotions.

In the teaser image released previously, the nine members of Nine Muses create the letter 'W' representing the first letter of their new song, "Wild." In risqué black lingerie outfits on a red-highlighted black and white photo, the sexy girl group expressed confident seduction with their figures.

With the official release date set on May 9, Nine Muses will hold a showcase in Seoul on the 8th. An associate from their management company stated, "The showcase will center on fan involvement. We want to make it a mini concert with our fans at the club. The venue has offered complete backing in terms of lights, visuals, sound system and whatever else needed."

Also, at the showcase, they will reveal which of the members shot the R-rated collar bone image included in the teaser. On May 6, an extended teaser of "Wild"'s music video will be released.
