Just a few days ago, FIESTAR confirmed that they would soon be making a comeback with their second single, "We Don't Stop".

Just moments ago, FIESTAR's revealed a making of film to preview another track, "Sweet Love". A collaboration with Sweet Sorrow's Kim Yeon Woo, the song is a light acoustic ballad that is refreshing change from the electronic-dance tracks popular with idol groups.

Given Kim Yeon Woo's recent accident, it is unclear whether we will get to see some live performances of this song with FIESTAR and Kim Yeon Woo. In any event, the collaboration seems to have been successfully completed, with the creation of this lovely new song.

FIESTAR is expected to release their second single on November 9th.
