The newly blonde Secret's leader Hyosung had her past dug up by netizens. As many of you may already know, Hyosung used to be part of a girl group called Oh-Sonyeo, which translates to Five Girls. The group never debuted but is still well known for being the group that started the careers of Wonder Girls' Yubin, After School's UEE and now Secret's Hyosung. In 2005, Mnet aired a show called Let's Coke PLAY Battle Shinhwa. Hyosung won first place in the competition and later appeared in the MTV documentary Diary of Five Girls. Hyosung said, "I'm flattered that people are looking in to my past, but I'm kind of embarrassed." In the photos, you should be able to recognize Hyosung, Yubin and UEE. Since their disbandment, all five girls have revealed their individual talents at one point or another. Yubin, UEE and Hyosung joined a different girl group while Jiwon, ex-member of T-ara, and Gina Choi, back-up dancer for Hyuna's Change, are seeking to make their own debut. Check out a clip of Five Girls rehearsing: It makes you wonder how they would have fared if they debuted under Five Girls as planned.
