Three days before the official release of their ninth mini-album, WJSN released a music video teaser for the title track "Unnatural."

Starship Entertainment, the talent management agency in charge of the Korean members, first uploaded the "Unnatural" music video teaser across its social networking sites, as well as on the WJSN SNS, on the afternoon of the 28th.

The 22-second music video teaser begins with Eunseo, chic and stylish, walking in front of dimly-lit blinds. It is followed by brief sequences showing each member of WJSN - Bona, Yeoreum, Dawon, Dayoung, Exy, Luda, Soobin, Yeonjung, Eunseo, and Seola - featuring their visuals against starkly different backgrounds that hint at unique features for each of them in the upcoming music video - creating an overall aesthetic of elegance and charm, intended to draw the attention of their fans worldwide.

Lastly, a sample of the title track plays throughout the music video teaser, a more sensual intro that builds up as the images of the members run by then cuts immediately to feature the album logo and the announcement for its March 31 release.

The "Unnatural" music video was released together with the official mini-album of the same name. Leading the ninth EP from WJSN, "Unnatural" is a pop dance track with rhythmic beats and a swing of impressive uptempo that delivers addictive hooks telling the challenges of a girl's heart in expressing herself and how things change awkwardly in front of that special someone.

WJSN has been known for their shy and conservative appeal in their previous albums. However, with "Unnatural," the Starship Entertainment girl group is expected to show their mature and confident side.

Aside from the mysterious and strong personalities WJSN is set to release with the title track, other songs from the upcoming ninth EP also shows the members' maturity. "Last Dance," the second song in the album, is about the last moments of a relationship coming to its end while in "New Me," WJSN leads their fans to have the courage to explore a new side to their personality.
