Girls’ Generation members Sooyoung, Hyoyeon, and Yuri have once again joined together as their (as of yet) unofficial sub-unit SHY!

On July 16, Sooyoung shared four shots of the talented crew to her Instagram. She writes as the hashtags, “SHY,” “yeahmechaHOLIDAY” and then adds in Korean, “TaeTiSeo, be worried.”

Hyoyeon also shared a group shot of the trio to her own Instagram on July 16, and included the title “Yeah! Meccha Holiday” in her hashtags as well. Yuri shared both sets of photos to her Instagram too, showing her own excitement about their performance.

Girls’ Generation took to the stage at the SMTOWN Concert in Osaka on July 16, where Sooyoung, Hyoyeon, and Yuri teamed up to perform Aya Matsuura’s 2002 hit “Yeah! Meccha Holiday.”

Would you want to see these three promote as SHY?
