Seventeen announced on Friday (Sept. 24) that the K-pop boy band will release its ninth EP, Attacca, on Oct. 22.

The 13-member group shared a red-tinted photo in which they’re seen walking at the bottom of what looks like an emptied swimming pool with their backs turned toward the camera on their socials.

Attacca is part of Seventeen’s 2021 “Power of Love” project, which also includes their last project Your Choice and Wonwoo and Mingyu’s “Bittersweet” single and centers on exploring different aspects of love found in life.

Attacca comes just five months after Seventeen’s eighth EP Your Choice, which was released on June 18 via Pledis Entertainment. Your Choice earned Seventeen their first No. 1 effort on the Top Album Sales chart (which is also the third overall effort for a K-pop act), as the mini-album sold 20,500 copies in the U.S. in the week ending June 24, according to MRC Data — the act’s best sales week yet. Your Choice also arrived at No. 15 on the Billboard 200 all-genre albums tally, their first entry on the chart.

“We’re just extremely grateful. Like seeing that, we felt like [having our work] paid off is an understatement. And hopefully, we can reach out to more and more CARATs [Seventeen’s fandom name] with every comeback,” Vernon told Billboard in an interview.
