Spoilers for Episodes 1 and 2.
The most consequential twist in 100 Days of Deception is not simply that an assassination attempt goes wrong. It is that Yoo So-ran is not the only person trying to kill Sato Shinichi. Episode 2 clarifies the identity of the other attacker: Geum Seok-jung, who entered the operation disguised as a cake deliveryman. His arrival turns a carefully prepared plot into a chaotic confrontation in which every character has a different reason to hide the truth.
Who is the second assassin?
The man initially concealed behind the cake-delivery disguise is Geum Seok-jung, played by Kam Woo-sung. His target is the same official targeted by So-ran: Sato Shinichi, the powerful colonial administrator portrayed by Jin Seon-kyu. The overlap is more than coincidence. So-ran has spent years seeking revenge for her daughter's death, while Seok-jung is connected to the resistance struggle and to So-ran's painful past.
Sports Chosun's recap of Episode 2 reports that a gunfight broke out between Seok-jung and Hideo. In the confusion, Suzuki was shot, Seok-jung escaped, and So-ran recognized the attacker as the husband she had not heard from for 13 years. That revelation makes the failed operation personal in a way the other characters could not have anticipated. Read the Episode 2 recap from Sports Chosun.
Why the cake-delivery disguise matters
The disguise gives Seok-jung a way to approach a guarded target without immediately revealing his identity. It also creates the episode's central misdirection: Ga-kyung and Hideo are forced to react to a threat before they know how the attacker fits into the larger story. The delivery role appears ordinary, but in this drama, everyday routines can conceal political violence.
The sequence also shows how fragile So-ran's plan has become. She and Philip have built a cover around their marriage and their attempt to reach Shinichi. An independent attacker changes the timing, raises the risk of exposure and makes it harder to control who survives the encounter.
The gunfight changes the story for So-ran
For So-ran, the revelation is devastating because Seok-jung is not merely another resistance operative. He is her long-missing husband, whose fate has remained uncertain for 13 years. The episode leaves her facing an impossible collision between the revenge mission that has shaped her life and the person she has been trying to find.
The Korea Times' October 13 review also highlights the emotional weight of So-ran's encounter with her husband and the grief she carries after losing her daughter. That context makes the second assassin twist more than a suspense device: it connects the plot's violence to the lasting damage suffered by a family under colonial rule. Read The Korea Times' review.
What the twist means for Hideo and Ga-kyung
Hideo's encounter with Seok-jung adds another fracture to his already complicated life. He works inside the administration targeted by the resistance, yet his own background and his adoptive father's suspicion leave him far from secure. Ga-kyung, meanwhile, becomes a witness whose knowledge could expose multiple people. Her attempt to survive the night brings her closer to a role she did not originally choose: spying for the independence group.
The result is a strong dramatic engine for the next episode. The authorities want to identify and punish the attackers, So-ran must decide what her husband's return means, and Ga-kyung must protect herself while navigating Hideo's suspicions. Each character has information the others need, but sharing it could be dangerous.

The second assassin was Geum Seok-jung, played by Kam Woo-sung. He disguised himself as a cake deliveryman while targeting Sato Shinichi. Episode 2 reveals his connection to Yoo So-ran: he is the husband she had not heard from for 13 years.
