On December 23 KST, they will be dropping their original holiday song "Hello Christmas." The song is being described by their agency AAP.Y Entertainment as a medium tempo ballad of the jazz pop genre that is combines the Christmas mood with the feeling of a Disney movie soundtrack.

Lee Mi Dam gained a large following in 2019 through his participation in both 'YG Treasure Box' and 'Produce X 101,' while Jung Myung Hoon, who also was a contestant on 'Produce X 101,' is also known for having been a long-time Brand New Music trainee.

Meanwhile, the two trainees will be holding special Christmas fan meeting on December 25 in Seoul.
