SBS drama "Master's Sun" showed Joo Joong-won (So Ji-sub) asking Tae Gong-sil (Kong Hyo-jin) to be his shield.
Tae Gong-sil saw his dead girlfriend Cha Hee-joo (Han Bo-reum) as a ghost and told him that she told her why she was bad. He asked if she told her who The Accomplice was but Gong-sil said, "She said she can't say who to protect that person".
Joo Joong-won remembered Cha Hee-joo had said, "I wish you were very sick" and suffered. When Tae Gong-sil tried to get up and leave he asked her to stay so that the ghost of his ex wouldn't see him this way".
This time Joo Joong-won needed Tae Gong-sil as a shield.
