In the drama, Ji Sung plays Cha Do Hyun, a third generation chaebol with dissociative identity disorder. The character has seven different personalities and Ji Sung’s ability to inhabit the different personalities is impressive. His look changes according to the personality he is portraying and two different looks can be seen in behind-the-scenes cuts from the February 9 episode of “Kill Me, Heal Me.”
One look in the photos is of Ji Sung is Cha Do Hyun. Though typically serious, Cha Do Hyun looks cute as he reacts to something surprising Hwang Jung Eum says, with his mouth agape and his eyes wide. In another still, Ji Sung looks adorable as he spaces out and purses his lips cutely in between filming.
The other look shown in the stills is of Ji Sung acting as Yo Na, a 17-year-old girl who loves idols. Ji Sung is wearing cute rabbit pajamas, which includes a hood with bunny ears attached. In one still, a staff member is seen applying lipstick, nicknamed “Yo Na tint.” Ji Sung also shows his professional side in other stills, carefully looking over his script in one photo and monitoring his scenes in another.
