The group is still going strong despite being one member short, with a possible comeback this month. f(x) first entered the K-Pop world with their single "La Cha Ta," which was released on September 1, 2009. Six years and many more singles and albums later, the group is one the most widely-known K-Pop acts both domestically and abroad! 

Amber, in celebration of the group's sixth anniversary, posted an inspiring and sweet message on her Instagram thanking all the loyal fans who played a big part in making her dreams come true.

Happy sixth f(x), and may you girls experience continued success in the future!
