Weeekly will be treating fans to a bright holiday carol!

The girl group will be participating as the first artists of a new music story project called the 'YAOKI Project', which follows the story of a cat from outer space named YAOKI. After arriving on earth, YAOKI learns about humans through music. 

The first music release through the 'YAOKI Project' is Weeekly's "Happy Christmas", set for release on December 9 at 6 PM KST. The track features a bright and warm melody, topped with Weeekly's youthful and refreshing charms.
