Ji Sung

Ji Sung (born Kwak Tae Geun) is a South Korean actor with talent agency Namoo Actors. As his parents were both educators, it was expected of him to also enter the profession. But in his sophomore year, his father bought him a VCR, allowing him to view ‘Rain Man’. Dustin Hoffman’s performance made such an impression on him, that he decided to become an actor, despite his father’s objections.

When studying at the Theatre and Film at Hanyang University in 1999, his first- ever audition was for the campus drama, ‘KAIST’. Screenwriter Song Ji Na, so taken with the young upstart, wrote in an entirely new character for him, creating the actor’s break-out performance.
Up until that time, Tae Gun had been using the stage name ´Choi Ji Sung’ but at his manager’s suggestion, dropped the surname ´Choi’, becoming simply ´Ji Sung’.

Ji Sung met actress Lee Bo Young on the set of 2004 TV series Save Last Dance for Me, and they confirmed their relationship in 2007. They got married on September 27, 2013.
In January 2020, on the TV show RUN, Ji Sung revealed that he suffers from Spondylosis, a condition that results in constant pain in the lower back.
