YMC Entertainment, a management company of Wanna One, said on December 20, "Wanna One has recently taken a music video and will release a new album on the 19th of next month."

Wanna One released a picture of a teaser titled 'Golden Age Begins' on Twitter before.

Wanna One overcame the limit of being a cable survivor, worked on various programs beyond the terrestrial thresholds, and collected various trophies including various new songs at various awards ceremonies. It is noteworthy that those who come back in about four months will continue their momentum in this activity.
