Disbandment and Future Activity

In 2011, two subunits of Coed School were formed. Each group consisted of only male members, SPEED, and female members, F-ve Dolls. SPEED released their debut album which was a remake version of T’ara’s popular single, Lovey Dovey.

SPEED held their first stage performance when promoting “Lovey Dovey-Plus” on the KBS2 Music Bank. SPEED was lucky because of the support of senior artists of their label company.

SPEED made frequent line-up changes throughout their relatively short lifespan. Old members left while new members were swiftly recruited. Kwanghaeng left SPEED in September 2012. In November 2015, MBK Entertainment took down the official profile page of SPEED and F-ve Dolls. Even though there was no official announcement, fans realized that it was meant as SPEED’s disbandment.
