The boys released a teaser for their song featuring Ara and member Kiu. The teaser starts off quite roughly with Kiu telling a girl (presumably Ara), "F*ck off, you b*tch", and then transitions into Ara crying.

'December 24' adds K-Much's soft vocals onto a dreamy drum beat. The acoustic guitar melds with the sad lyrics throughout the song. The lyrics talk about breaking up with a loved one on Christmas Eve.

The song will be released on the 17th!
