South Korean boy band Wanna One returned with new music Monday.

The K-pop group released the album 1-1=0 (Nothing Without You) and a movie version of their "Beautiful" music video.

1-1=0 (Nothing Without You) is a repackaged version of Wanna One's debut EP, 1x1=1 (To Be One).

The boy band promoted the album at a press event Monday in Seoul, according to The Korea Herald.

"While we've showcased our energetic and passionate sides as rookies through our previous works, we tried to relive the time before our debut, when our days were full of anxieties and contemplation of our future," Hwang Min-hyun said.

1-1=0 (Nothing Without You) includes 11 tracks, including "Beautiful" and remixes of the group's hits "Energetic" and "Burn It Up."

The movie version of the "Beautiful" music video features actor Cha Seung-won.

Wanna One was formed in Season 2 of the Korean reality competition Produce 101 this year.
