24K (투포케이) is a boy group under Choeun Entertainment. They debuted on September 6, 2012 with the mini-album Hurry Up. The original meaning of their name was "2 dancing machines and 4 main vocals," but through numerous lineup changes it has evolved to mean "like gold, to shine forever."
In 2019, 24K saw the departures of all but two members: Changsun and Kiyong. New members Xiwoo and Imchan were revealed on the group's Instagram, and on November 18, the group was confirmed to be preparing for a comeback in the first half of 2020 with yet more new members.
