In "Kill Me Heal Me" Ji Sung and Hwang Jung Eum's kiss ended up not happening.
On the 6th episode of MBC "Kill Me Heal Me" broadcast on January 22nd, Cha Do Hyun (played by Ji Sung) had tried to Oh Ri Jin (played by Hwang Jung Eum). Nonetheless, he failed in his efforts to kiss her.
On this day, Cha Do Hyun started to feel confused as his heart started beating for Oh Ri Jin. At this time, Oh Ri Jin said, "Are you Shin Se Ki by any chance?" Cha Do Hyun said, "Oh Ri Jin, are you still confused about me and Se Ki? Do you want me to make sure that it's not confusing?" and went near her.
Cha Do Hyun wanted to kiss Oh Ri Jin and put his face into her face. Cha Do Hyun said, "I'm sorry. I don't use my heart by myself but there's a lot of other personalities and the lines got jumbled up."
Nonetheless, Oh Ri Jin was furious. "Why do you stop in the middle? A man should go to the end and why do you lack such enthusiasm? I have something to check too so go ahead" and was very proactive.
