Kang Ji Hwan was at risk of being sacrificed because of a heart transplant to Daniel Choi.
On the 1st episode of KBS 2TV Monday/Tuesday drama "Big Man" broadcast on April 28th, Kang Dong Suk (played by Daniel Choi) who was the heir of Hyunsung Group went through a car accident and needed a heart transplant and the target was pointed to as Kim Ji Hyuk (played by Kang Ji Whan).
On this episode, Kang Sung Wook (played by Um Hyo Sup) hears from the doctor, "If there is a donor from the family then there's no need to wait for surgery." At this, Kang Sung Wook ordered secretary Do Sang Ho (played by Han Sang Jin) "Isn't there a person like Dong Suk somewhere in the world? Let's bring him even if he's dead."
This was so that people who would have a high rate of success in heart transplants would be written as a son and would be judged as brain dead to transplant their heart to Kang Dong Suk.
As a result, Kim Ji Hyuk was a target as his success rate was 95%.
Meanwhile, on this date, as a result of Do Sang Ho's strategy, Kim Ji Hyuk becomes a forced brain dead patient and undergoes surgery. However, at the time that the surgery was about to be carried out, there were brain nerves that were found and the transplant was stopped. However, the patient could be brain dead at any point.
