Secret is a four member girl group signed to TS Entertainment. Even before their debut, they have gained an incredible amount of popularity for their polished vocals and stage performances. One of the unique traits that seperates Secret from other female Idol groups is that each new album Secret releases has a different image and music concept. Like their tough girl image shown with “Madonna“ and a cutesy image with their hit single, “Shy Boy.” The girls of Secret were at first very depressed about their new image for “Shy Boy“, to the point of even shedding tears. Ironically, “Shy Boy“ became their most popular song and they even won their first “#1 Song“ award in various music programs.
