"Gu Family Book" Lee Seung Gi throws himself in order to save Bae Suzy's life.

April 22, the 5th episode of the MBC drama "Gu Family Book" featured Choi Kang Chi (Lee Seung Gi) saving Dam Yeo Wool's (Bae Suzy) life by throwing himself in front of her.

Jo Kwan Woong (Lee Sung Jae) sends two men who use magic to multiply into a group of fighters to the Park Moo Sol (Uhm Hyo Sup) household. Park Moo Sol is saved by Han Noh (Park Joo Hyung) and is able to keep his secret about Choi Kang Chi and his bracelet.

At the same time, Choi Kang Chi and Dam Yeo Wool fights against the group of men trying to kill them. They have to find the real human to get rid of all the other copies that are attacking them. Both Choi Kang Chi and Dam Yeo Wool receive various wounds in the process.

Dam Yeo Wool almost gets killed while she is looking away but is saved by Choi Kang Chi, who blocks the blow with his own arm. The sword goes into his arm but Dam Yeo Wool's life has been saved.

Dam Yeo Wool gets a flashback of her past when Choi Kang Chi saved her once before. He had saved her from a monstrous dog that was about to attack. Even though he does not remember her now, Choi Kang Chi had comforted her by saying things like, "Don't worry, I'm going to protect you."

Choi Kang Chi saved Dam Yeo Wool's life three times already since the very first time they met.
