The mysterious visual of "Concept Master" WJSN has been unveiled.

Starship Entertainment released the first concept photo of its special single album "Sequence" on its official SNS on June 14th.

The first concept photo showed the mysterious images of Eunseo, Yeoreum, Luda, Yeonjung, and Bona.

From Eunseo, who showed subtle charisma, to the summer when innocence stands out, Luda, who has a fairy-like image, catches the eye. In addition, even Bona, who is showing off her captivating feeling and unrivaled goddess beauty, is adding to the excitement of fans by showing a completely different charm of mermaids in the same concept.

As "Sequence" is the first new release in a year and four months since "UNNATURAL" released in March last year and for the first time since winning "Queendom 2," more attention is being paid to the new performance capabilities that WJSN will show.
