On the February 5th episode of MBC drama, "Kill Me, Heal Me", Cha Do-hyeon (Ji Seong)"s another personality, Shin Se-gi came up to the surface and then he got angry with Oh Ri-jin (Hwang Jeong-eum).
Shin Se-gi found Oh Ri-jin (Hwang Jeong-eum), who fell asleep together in Cha Do-hyeon"s bedroom. He became angry and said, "Why are you here? In Cha Do-hyeon"s bedroom?"
Oh Ri-jin (Hwang Jeong-eum) explained, "I"m his personal physician now. I stayed here only for a little bit because it seemed he"s having a nightmare"
Shin Se-gi became teary-eyed and asked her, "So you can kill me and you can get rid of me?" He dragged her out of the room saying, "I can"t let you stay next to Cha Do-hyeon".
Oh Ri-jin (Hwang Jeong-eum) said, "Listen. I"m just trying to be a fair mediator between Cha and Shin. Cha and Shin, you really need to understand each other".
But Shin Se-gi asked her, "It only ends when one of them disappears. You"ll have to choose one of the two eventually. Are you going to be happy if I"m gone?"
Oh Ri-jin tried to be nice with him and said, "Cha didn"t ask me to get rid of you. He wants to compromise with you. I"m just a mediator. It means it"s not up to me to make the decision". But Shin Se-gi said, "You completely fell in love with Cha Do-hyeon. Do you think he"s letting you stay just out of innocent mind?" and then Shin Se-gi shed tears.
He also said, "Cha Do-hyeon violated the rules. It"s impossible to co-exist peacefully with him any longer. I"m going to make him pay for this in my own way. That"s the rule of this game". And then he left the place.
