Decided to protect Gong Hyo-jin even after knowing her true identity (Married Woman Killer)

Lee Dong-jin asked, "Are you in league with Kingfisher? Is your embargo Kingfisher?" and Kwon Tae-seong replied, "No. I'm in league with you," revealing that the man he saw was Kingfisher and that he must protect his family from him.
Kwon Tae-seong's choice was Yu Bona. Upon returning home, Kwon Tae-seong hugged Yu Bona and spent a joyful time with his family at the amusement park.
