The album didn't include rapper Bekah, as she was on holiday during promotions.

The “Happy PLEDIS” album is a project album purported to give back the love and support the artists have received from their fans; it also asks people to look around themselves with a warmer heart in the winter season.

Pledis Entertainment's artists Son Dambi, After School, and their sub-unit group Orange Caramel each released their own version of the Happy Pledis album.

"Fans will be able to see a lovelier side of After School through this album, along with a sweet melody that will make this winter season that much more beautiful."

"[1] A portion of the profits from the “Happy PLEDIS” albums was donated to the “Save the Children” organization.
