24K (투포케이) is a boy group under Choeun Entertainment. They debuted on September 6, 2012 with the mini-album Hurry Up. The meaning of their name at their debut was "2 dancing machines and 4 main vocals". However, the meaning of 24K has changed to "like gold, to shine forever."
In 2019, 24K had a line-up change that left only two members, Changsun and Kiyong, in the line-up. They were joined by Xiwoo and Imchan not much later that year, and on November 18, the group was confirmed to be practicing for their comeback in the first half of 2020 with yet to be revealed members.
