In "Kill Me Heal Me" Ji Sung declared war on his multiple personality disorder.
On the 6th episode of MBC "Kill Me Heal Me" broadcast on January 22nd, Cha Do Hyun (played by Ji Sung) was threatened by Shin Se Ki, which was one of his multiple personalities.
On this day, Shin Se Ki was upset at Cha Do Hyun for trying to kiss Oh Ri Jin (played by Hwang Jung Eum). Shin Se Ki said in the media clip, "If you touch my woman, I'm going to make sure you know that your woman is going to be at risk" he warned.
Cha Do Hyun then called Han Chae Yeon (played by Kim Yoo Ri) and made sure that she was safety. Shin Se Ki already predicted such behavior of Cha Do Hyun and used this in a counteractive way.
Shin Se Ki said, "If you never want to go through this hell again then mark my words. The fact that your woman is going to be in danger if you touch my woman. This is the first rule for you and I to be coexisting in people."
In the end, Cha Do Hyun said, "Shin Se Ki you jerk" and started to explode in anger.
