SM Entertainment teased the public announcing that it would release a sub-unit group of the top girl group Girls Generation.

The name TaeTiSeo gave it away on who would be the members. The name is derived from the names Taeyeon, Tiffany, and Seo-hyeon. They seek to show a different side of themselves and style of music through their subunit activities.

As soon as the title song "Twinkle" hit the market, it along with the other songs on the mini-album, skyrocketed on music charts across the country.

TaeTiSeo proved that they don't need all 9 members of Girls Generation to create hits!
