Healer () is a 2014–2015 South Korean television series starring Ji Chang-wook, Park Min-young, and Yoo Ji-tae. It aired on KBS2 from December 8, 2014 to February 10, 2015 on Mondays and Tuesdays at 22:00 (KST) for 20 episodes.

Though the drama received modest ratings in its home country, it gained a fanbase overseas and made Ji Chang-wook known outside Korea.

Synopsis
A decades-old incident involving a group of five friends who ran an illegal pro-democracy broadcasting station during the Fifth Republic in South Korea brings together three different people—an illegal "night courier" with the codename "Healer" (Ji Chang-wook) who possesses top-notch fighting skills, a reporter from a second-rate tabloid news website (Park Min-young), and a famous journalist at a major broadcast station (Yoo Ji-tae). While trying to uncover the truth from that 1992 incident and a series of present day murders, they grow into honest reporters who try to blur the lines of conflict between truth and reality, even if that means fighting media honchos.

His ultimate goal is to save money and buy an uninhabited island off the coast of Panama and to live there alone, but that changes after being given an order by his client, Kim Mun-ho, to find and protect a girl named Young-shin from the people who want her dead but he later falls in love with Young-shin.
