The Master's Sun Korean Drama Cast

Several years ago Kong-Sil (Kong Hyo-Jin) was involved in an accident. Since that incident, Kong-Sil is able to see and hear ghosts. She's also terrified of the ghosts that appear constantly around her. Because of this, she's unable to live a normal life. Kong-Sil lives in a rooftop room at an extended stay inn. She makes a living by doing odd jobs at the inn, including cleaning.

Meanwhile Joong-Won (So Ji-Sub) is the president of an extravagant shopping mall named Kingdom. He is also arrogant and calculative. Everything relates to him in terms of money.

One raining evening, Kong-Sil goes to room 404 to clean, but she sees another ghosts. She freaks out and runs up to her rooftop room. The ghost, who looks like an old woman, appears right next to her again. Kong-Sil then does the old woman ghost a favor and goes to her home. She hands the ghost's son a bankbook with more than 10,000 dollars in the account.

Joong-Won sits face to face with a man who owns land that he needs to build a golf course. The man tells Joong-Won that his deceased wife does not want him to sell the land. Joong-Won doesn't believe in ghosts and ignores him. He pulls out a contract which the man's children already signed. Joong-Won is able to get the man's signature.

On his way back from that meeting, Joong-Won is driven by his assistant (Choi Jung-Woo). The driver then sees a woman thumbing for a ride. Joong-Won tells his driver to ignore the woman, but a light suddenly shines on them and the car stops. At this time, Kong-Sil hops into the car and thanks them for picking her up. Kong-Sil unintentionally touches Joong-Won and feels something unusual. Later, the car pulls over at a highway rest stop. While walking back to the car, Joong-Won sees Kong-Sil talking to someone, but there isn't anyone else there. Thinking she might be crazy, Joong-Won turns around, but Kong-Sil grabs his arm. She discovers that whenever she touches him, the ghosts around her disappear.

Back at her rooftop room, Kong-Sil is terrified by the ghosts around her as usual. She thinks back to Joong-Won and how the ghosts disappeared when she touched him. Kong-Sil decides to go Kingdom shopping mall to meet Joong-Won again.
