Biography
Biography
Lee Jae-jin (Korean: 이재진; Japanese: イ・ジェジン; born December 17, 1991) is a South Korean musician and actor. He is a member of rock band F.T. Island, where he serves as the bassist and 2nd vocalist. He has also contributed to F.T. Island's body of work with several compositions of his own.
F.T. Triple
In January 2009, members Choi Jong-hoon, Choi Min-hwan, and Lee Jae-jin were put into the sub group "A3". This group debuted at the 2009 New Year concert "My First Dream" held at the JCB Hall in Tokyo, Japan on January 2, 2009. Jae-jin performed as the vocalist and bassist. The group's name was "A3" due to each of the three members having type A blood. This group was formed to help take up some singing time during their concerts, so that main vocalist, Lee Hongki, would not overstrain his voice.
In late 2009, A3 was renamed F.T. Triple and began working with Lee Jae-jin on guitar instead of bass. They released the single "Love Letter" and began performing on music shows. During this time, F.T. Island's main vocalist Lee Hongki was busy filming a drama and guitarist Song Seung-hyun was involved in several variety shows.
Acting career
He made his acting debut in the 2007 KBS2 sitcom Unstoppable Marriage. Lee Jae-jin was a main cast member while the other members made a cameo appearance. In the sitcom, he played the role of Wang Sa-baek (Sim Mal-yeon's fourth son), and appeared regularly on the show.
He also did a cameo in Style [Ep6] (SBS, 2009) and On Air (SBS, 2008).
In 2009, he was cast for the main role in the musical Sonagi, which is based on the classic Korean short story "Sonagi" written by Hwang Sun-won. He got the role as a young boy.
In 2013, he was cast in a Korean production of High School Musical along with AOA member Choa.
In 2021, Lee starred in the stage play Vampire Arthur, a stage play following his discharge from military service.
Personal life
Lee's older sister, Lee Chae-Won was cast in the SBS drama On Air, where she played the make-up artist for Oh Seung-ah (Kim Ha-neul).
On January 21, 2020, Lee began his mandatory military service. He is the second FT Island member to enlist, after FT Island member Lee Hong-gi enlisted on September 30, 2019. On August 1, 2021, Lee was discharged from military service.
