F.Cuz

Pre-debut

Jinon, Raehyun, Kan, and Yejun all attended the Anyang High School of Arts in Anyang; Jinon was their senior while Raehyun, Kan, and Yejun were in the same graduating class. While in Anyang, Jinon, Kan, and Yejun all participated in a dance team that had included famous K-Pop star Rain.^[10] Out of all the F.Cuz members who attended school in Anyang, Jinon had one of the busier pre-debut careers. In 2005, Jinon joined a project group named GM6, now known as Supernova, and began trainee activities.^[11] However, Jinon withdrew before their debut and suffered major health issues as a result; he battled depression and several eating disorders.^[11] Jinon also pursued acting and achieved some notoriety due to his similarities to Kwon Sang Woo.^[11] In 2009, he appeared in Cinderella Man as a younger version of Kwon Sang Woo's character.^[10] Jinon also had a role in SG Wannabe's "Gashiri" music video alongside T-ara's Eunjung.^[10]

Like Jinon, Raehyun and Kan also pursued acting. Raehyun's pre-debut career includes several dramas (Gloria, Over the Rainbow, Chosun Police (Season 3), Beautiful Life, and Rock, Rock, Rock), an appearance in the movie See You After School, and a Samyang ramen CF.^[12] Kan appeared in the dramas Soul and Assorted Gems.

LeeU had always been a witness to the music industry due to his father, the famous trot singer Sul Woon Do. From an early age, LeeU had wanted to pursue a singing career, so much so that he lost sixty pounds in one month during his first year of junior high.^[13] Later, LeeU became a successful ulzzang and appeared on many variety programs with his father.^[14] LeeU also had a short solo career under the name "U" (Korean: 唯);^[15] he appeared on the SBS Drama Gourmet OST with "Listen to You" (Korean: 그대를 듣죠) and featured on a song with Taru (Korean: 타루) called "오! 다시 (Oh! Again)."

Daegeon began his idol career under Xing Entertainment, a company most known for housing future members of U-KISS, Beast, and The Boss.^[16] Daegeon eventually moved on to Golden Goose Entertainment and debuted as a member of Double B 21, now known as Apeace.^[16] He participated in their S.O.S. promotions, but left the group shortly after.

2010: Jiggy, No One, overseas activities, and Gorgeous

F.Cuz was officially announced by CAN&J Entertainment on December 6, 2009.^[17] Following the announcement, each day one member would introduce themselves to the public through a short video that showcased their talents; the videos amassed over 30,000 views.^[18] In anticipation of their debut, F.Cuz began filming the music video for "Jiggy," their debut release, on December 15, 2009.^[19] "Jiggy" was digitally released on January 8, 2010, and they held their debut performance the same day on KBS' Music Bank.^[20][21] In February, it was announced that F.Cuz had signed with Taiwanese label SEEDMUSIC to pursue activities overseas.^[22] On March 8, "Jiggy" was digitally released in Taiwan and Hong Kong.^[23] On March 11, 2010, F.Cuz made their Korean comeback with their first mini-album and title song "No One."^[23]

F.Cuz returned with a new album called "Gorgeous" with the title track "Midnight Sun" on November 18, 2010. They released another single from the album, "친구졸업 (Friend's Graduation), with the English title "Wanna Be Your Love". This song has a cute and bubbly image that completely contradicts the dark concept of "Midnight Sun". In January 2011, member Kan was involved in a serious car accident going back to Seoul after filming for the drama Athena: Goddess of War. He, his manager, and four other people in the car received major and minor injuries after the car slipped on ice and crashed, forcing the group to halt activities for their new song.

2011–13: LeeU's withdrawal, For Century Ultimate Zest, Hello Again

On May 21, 2011, Can Entertainment announced that Lee-U would be leaving the group in August after releasing their Japanese debut single. The record company cited musical differences and Lee-U's desire to focus on a career as a solo singer. Can Entertainment and Lee-U's agency, Castle J Enterprise, came to an agreement to withdraw him from the group.^[24] The group added two new members, Daegeon and Raehyun, to replace Lee-U.

On April 27, 2012, F.Cuz released their new mini album "For Century Ultimate Zest." They made their comeback with promotions for the title track "NO. 1."

In August 2012, they released "꿈꾸는" (Dreaming I), a single.

2014–2016: One Love, Bargaining for Love, Two of Us, Contract Expiration and U Concert

F.Cuz released a Korean single titled "One Love" on March 27, 2014. This marked their Korean comeback after almost 2 years since they spent most of 2013 promoting in Japan. The group left to Japan in July to promote the Japanese version of "One Love", "Feeling My Soul".

On September 12, 2016, it was announced through F.Cuz's fan-club that the members would not renew their contracts once they expired on September 30, leading them into becoming an independent group.^[25]

In October 18, they changed their logo and the meaning behind it to "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.
