On August 6, SM Entertainment announced that Girls' Generation's unit group TTS was still preparing for their comeback, but the exact date has not been confirmed.

SM Entertainment staff stated: "The three members are currently preparing for the album. However, nothing's been set in stone yet. We'll be posting announcements as it gets confirmed, so please continue to support us."

Meanwhile, TTS began their promotions in 2012 with "Twinkle" and demonstrated the power of Girls' Generation through their popularity.
