About Ji Sung

Ji Sung, born Kwak Tae-geun, debuted in 1999 and became a Hallyu name with All In (2003). On our site he leads The Apartment Job and The Judge Returns (2026), Connection, The Devil Judge, Familiar Wife and Kill Me, Heal Me (2015), which won him the MBC Drama Awards grand prize.

  • Debut

    He auditioned for the 1999 campus drama KAIST, where the screenwriter wrote a part for him; he first used the stage name Chae Ji-sung before dropping the surname.

  • Role

    Most actors avoided the second male lead in All In (2003) for fear of comparison with Lee Byung-hun, so Ji Sung asked the director for the part himself.

  • Education
