On the 18th episode of SBS Wednesday/Thursday drama "Heirs" (script Kim Eun Sook, director Kang Shin Hyo) broadcast on December 5th, Kim Tan (played by Lee Min Ho) tells his father Kim Nam Yoon (played by Jung Dong Hwan) that he'll leave the house with his mother.
However, Kim Nam Yoon prepared a party for his birthday to bring him back home and Kim Won (played by Choi Jin Hyuk) who was not so friendly congratulated Kim Tan.
Meanwhile, Cha Eun Sang (played by Park Shin Hae) is invited to Kim Tan's birthday party with the invitation of Kingdom Group. She is wearing a dress and stood in front of Kim Tan and said to her, "We have to be brave today. Can you do this?"
The two entered the party scene. Kim Tan faced so many reporters with Cha Eun Sang and asked nicely whether she was nervous. He also said, "It might be a bit hard. But let's go forward nonetheless" and said something mysterious.
