Currently, Ji Sung is amazing everybody with his incredible ability to act out multiple different personalities with the snap of a finger in his MBC drama, 'Kill Me, Heal Me,' which sadly ends this week.  However, it might be good news for Ji Sung because it looks like the guy needs a break!

Because of the intense nature of the drama when it comes to acting and Ji Sung's immense focus in his character (or characters) from yelling or being hyper to crying, he was belatedly revealed to have put the set in a state of emergency back on March 3 when he suddenly lost his voice while preparing to film.  He had even recorded "Manchurian Violet" as a part of the drama's OST recently.  

Of course he was upset because of the detrimental timing of his voice loss.  While he calmed down due to the staff members' concern over his state, he still worried that the filming will get pushed back because of him.  He was told he needed to rest, but returned to the set, anyway.

An agency rep stated, "Ji Sung feels a really strong responsibility for the production. Despite people's suggestion that it'd be better if he rested some more, he said that it was actually more stressful for him to not be able to act, leaving everybody speechless.  It was a scene that had to be filmed during the day, so it was a situation in which the filming could not be halted.  He saw through this and acted while hiding signs of his pain.  

Even during the waiting time, he will only look at the script and plan the next scene, showing passion in everything.  As expected, everyone on set was touched by Ji Sung's consideration and fighting spirit."

The drama will be ending this week on Wednesday and Thursday, so make sure you stick through the conclusion!
