The behind story of old-school boy group g.o.d's 15^th anniversary project album teaser image was released.

The pre-release song was revealed on May 8, entitled "The Lone Duckling", ahead of their upcoming full-length album, which is to be released on July 12 along with a concert the following day. SidusHQ, who is in charge of the album management as well as its extensive marketing, posted the story behind the teaser image of "The Lone Duckling" via their official Facebook page on May 12.

They stated, "Joon Park, the eldest and subsequent leader of g.o.d, came up with the idea. The image is a parody of one of Bon Jovi's album photos."

SidusHQ added, "Bon Jovi is widely known as a group that composed, produced and performed extraordinary music for 20 years; they have become the world's muse. Taking this into account, the parody of the image was done in hopes of replicating that ideal; that g.o.d can also stay together for a long time and create music that can capture and stay inside people's hearts."

g.o.d's teaser image for "The Lone Duckling" is a parody of Bon Jovi's 1992 album Keep The Faith jacket photo.

"The Lone Duckling" is the creation of hitmakers Duble Sidekick. Instead of composing a track that follows the general music trend or offers a fresh sound, Duble Sidekick offers a ballad song that matches g.o.d's emotion and distinctive qualities. "The Lone Duckling" has sweeped music charts ever since its release.
