Donghak Rebellion (Donghak Peasant Movement) takes place in Hongjuseong (now Hongseong). Manhae, a boy who participates in the Donghak Rebellion as a 16-year-old, steals 1,000 nyang and sends it to military funds. At the age of 55, at Simujang in Seongbuk-dong, Manhae remarried while staying in a boarding house. While making a living by sewing his wife's wages, Manhae continues to resist Japanese imperialism by participating in the movement against the name change of the Chang clan and against the dispatch of Korean student soldiers along with writing. He takes over the military funds from Madam Baekhwa of Myeongwol in Yongjing. Lee Hwa-yeong hands over the military funds with Man-hae. In 1944, Manhae passed away at the age of 66. As the poem "Your Silence" flows, Manhae's achievements are introduced as highlights, and his subtitles flow.
