Youngbin, Inseong, Taeyang, Hwiyoung, and Chani have returned as SF9, kicking off the group's new 'FANTASY' album series. 

SF9's 14th mini album, the first of the 'FANTASY' trilogy, is dedicated to their loyal fans, also known as Fantasy. The album's sounds capture SF9's signature combination of sexy and refreshing charms across its 5 tracks. 

The group's title track, "Don't Worry, Be Happy", is a pop dance genre with rhythmic synthesizer, bass, and brass sounds. Members Youngbin and Hwiyoung took part in writing the lyrics, which feature well wishes for an ex-lover.
