They said, "It's been two years since we removed our helmets. Because so many people showed us love, they remember us by our helmets. It is our goal to be loved without our helmets."

Crayon Pop continued, "Every time we discuss concepts, we put forth numerous suggestions. We participated more in the concept developing process this time around. Wearing bell bottoms is an idea we suggested a year ago, but it was more fitting with this concept, and we designed the album cover and a new team logo. It's been such a long time since we made a comeback that it feels like we're debuting. Because it's our first full-length album, every member took care to participate in the [production] process. We want to show what we weren't able to thus far with this album. It's our first full-length album in a year and six months, so please look forward to it."
