On September 3, Girls' Generation appeared on MBC radio show, 'Kim Shin Young's Noon Song of Hope,' and talked subunits!
While the DJ and the girls were preparing to say farewell, Kim Shin Young asked about unit promotions. Tiffany replied, "TaeTiSeo wants to [come back] too," and mentioned a unit team they've made called SHY with Sooyoung, Hyoyeon, and Yuri.
Yuri explained they had made it simply as a joke, but fans had thought it was real. She added that it was a group for the members who could not make music or sing but were good at variety, making everyone laugh.
