F.CUZ (Korean: 포커즈, “Focus”), is a South Korean boy band that used to be managed by Tunes-Will Entertainment, and is now promoting as an independent group (before 2014 by CAN Entertainment). The group made their debut on January 8, 2010 with their first single, “Jiggy” on Music Bank. F.Cuz originally debuted as a four-member group (Jinon, LeeU, Kan, and Yejun), but LeeU made his departure on August 23, 2011 to pursue a solo career. F.Cuz promoted shortly as three-member group in Japan, but were joined by new members Daegeon and Raehyun in 2012. Their contract with Tunes-Will expired in September 2016, and they are now independent. The official fanclub for F.Cuz is ‘For U’ and their color is Twinkle Light Silver. The meaning of the group is “A five-points star” as in five members that complete F.CUZ, and “U+U = F.CUZ+FORU” as in the group and their fans being one.
