A 10- member girl group under SM Entertainment is divided into two groups namely F.Y.T (K) and F.Y.T (J) debuted in the year of 2010.  This two groups is said to be promoting in Korea and Japan at the same time. Their name was based on their image which represents the group's personalities. Their first single was "Chitty Chitty Bang Bang" that was released on May 16, 2010 and had their first live performance on May 20, 2010. During that year, F.Y.T already became famous, not only in Korea and Japan but in other parts of Asia and Europe, as well.

The following year, SM Entertainment debuted another boy group, EXO that was announced to be their counter group. F.Y.T's concept was adopted by EXO but the group was promoting in China. In every comeback stage, their concept is composed of their 3 images, which are Fierce/ y, Sweet/Cute and Talented, where they can showcase their other talents to see a new side of them.
