"Gu Family Book" Even after Bae Suzy discovers the truth about her twisted history with Lee Seung Gi, she continues to love him.

May 27, the 15th episode of the MBC drama "Gu Family Book" featured Dam Yeo Wool (Bae Suzy) learning that her father Dam Pyung Joon (Jo Sung Ha) had killed Choi Kang Chi's (Lee Seung Gi) father.

During the episode, Dam Yeo Wool goes into the woods by herself to find Choi Kang Chi. When she gets lost, she runs into Goo Wol Ryung (Choi Jin Hyuk). Goo Wol Ryung learns that Dam Yeo Wool is the daughter of Dam Pyung Joon then tells her that Choi Kang Chi's father had been killed by him.

As if she is in disbelief, Dam Yeo Wool takes out her sword and says, "My father is not a man who would kill an innocent person." However, Goo Wol Ryung tells her, "That beast had done nothing wrong and was very innocent. I guess you didn't have any idea. Does that mean Choi Kang Chi doesn't know it as well?"

Without revealing his identity, Goo Wol Ryung makes Dam Yeo Wool panic with the story of the past. Dam Yeo Wool begins to cry hysterically and screams. Hearing her cry, Choi Kang Chi suddenly appears.

Even though Dam Yeo Wool learned that her father had killed Choi Kang Chi's father, she could not forget about her love for Choi Kang Chi. When she returns home, Dam Yeo Wool asks Dam Pyung Joon, "Father, did you really kill Kang Chi's father? Is that why you are trying to split us apart?"
