"Gu Family Book" Lee Seung Gi decides to fight his own father in order to save Bae Suzy's life.

May 27, the 15th episode of the MBC drama "Gu Family Book" featured Choi Kang Chi (Lee Seung Gi) about to attack his father Goo Wol Ryung (Choi Jin Hyuk).

Choi Kang Chi treats Monk So Jung's (Kim Hee Won) wounds with great care. So Jung tells Choi Knag Chi, "I told you to run away, what are you still doing here? Your father is trying to kill you." Choi Kang Chi replies, "How could I call somebody my father when he is trying to kill me. Didn't you say before that I can never die?"

So Jung replies, "Beasts can kill other beasts" to which Choi Kang Chi replies, "If I can die, that means I could kill him as well."

However, So Jung says, "There is no way you will be able to defeat him. Why are you trying to fight against someone who you have no chance with?" Choi Kang Chi replies, "He messed with something that he shouldn't have messed with."

It is predicted that Choi Kang Chi will try to fight Goo Wol Ryung but appears that he will be too weak for the fight.
