This video (and post) is an entire day early because we will be busy. You're welcome.
Um... Yeah. Just watch it.
"According to an exclusive by Sports Chosun, SM Entertainment plans to launch a 4-member girl group made up of 3 familiar faces from the pre-debut team S.M.ROOKIES - Seulgi, Irene, and Wendy - and 1 more mystery member with resemblance to actress Kim Yoo Jung.
If this is true, then this new group would mark the agency's first girl group following f(x)'s debut back in 2009! According to what Sports Chosun has heard, the new group's concept is said to be an in-between of f(x)'s experimental concept and Girls' Generation's more mainstream style." allkpop.com
