Lee Seong-gye (Chun Ho-jin) set out for Kaesong to formally join politics, and Lee Bang-won (Yoo Ah-in) also followed his father to Kaesong. When Lee Bang-won arrived in Kaesong, he saw the Quanwen clan who disregarded the lives of the people just to fill their own stomachs, and he could not suppress his inner anger. Lee In-gyeom (Choi Jong-won), who was already wary of Lee Seong-gye's political career, invited Lee Seong-gye to his home and held a banquet. At the banquet, Lee In-gyeom showed him a street play about his betrayal of Cho So-sang (Ahn Gil-kang), who was once like a brother. After the banquet, Lee Seong-gye bowed his head to Lee In-gyeom in order to let Lee In-gyeom keep the secret of his betrayal of Cho So-sang, and Lee Bang-won witnessed this scene.
