Gwanghae (Cha Seung Won) presses Hawi (Lee Yeon Hee) hard, but her quick wits get her out of an awkward situation. The King remains dubious about her identity and Kim Gae Shi (Kim Yeo Jin) is also sure that she knows her because the master craftsman didn't ask her who she is when she visited her. The King orders the faithful servant to check up her household register as soon as possible.
Meanwhile, Queen Inmok (Shin Eun Jung) clings to her last hope with the bracelet which she gave Princess Jeongmyeong before she died in the ferry. The guard who picked it up secretly reports to Kim Gae Shi about it and the Queen's excessive reaction. Heo Gyun (Ahn Nae Sang) overhears their conversation and he senses something big is brewing.
Hawi packs to bless herself from danger, but Hong Joo Won (Seo Kang Joon) misunderstood her intention to let her move into the dorms in Hawgidogam. When they go to the workplace, they find the head of the sulfur department falls to the ground in smoke. They are shocked at another tragedy, however, it is a surprise party for Hawi, the best contributor to the organization's reconstruction. She realizes how much Hawgidogam means to Joseon and the whole nation.
Hawi asks Joo Won if he had seen the bracelet. Kang In Woo (Han Joo Wan) heard about the lost beads from his friend asks Heo Gyun where he can find someone and he notices that it is the beads of the Queen. In Woo brings Hawi to a shop for fashion accessories and let her wear a bracelet as a present. Joo Won also bought a white bracelet for her doesn't know how to give her the present.
Joo Won goes to the palace without his official uniform at Gwanghae's behest. The King takes the young subject to his safe house when he meets secret emissaries sent by Nurhachi of the Jin Dynasty. Joo Won is worried about the King communicating secretly with the enemy, but Gwanghae pledges to defend Joseon and the people from an upcoming war between Ming and Jin although he will stick his neck out.
Gwanghae goes to Mohwagwan (a place where envoys dispatched from Ming and Qing China were received as diplomatic guests) to welcome envoys from Ming Dynasty and waits for them for a while, but they don't come. He rushes Gyeongungung where the envoys have arrived to say hello Inmok and look hard at the Queen.
Joo Won's father calls men collected from the soil sample in Gyeongungung and the sulfur specialist as directed by the Queen's man. Jeongmyeong is in fear that her lie would be discovered and runs away. She is caught by armed men on the run and wakes up in a strange place after she gets doused with water. Heo Gyun asks if she is a cat's paw of Gwanghae as though he interrogates the master craftsman.
