Spoiler warning: This article discusses the assassin storyline and major events from Episodes 1 and 2 of 100 Days of Deception.
Quick answer: The cake-delivery disguise is more than a suspenseful shock in 100 Days of Deception. The gunman is Geum Seok-jung, played by Kam Woo-sung, and his attack reveals that Yoo So-ran’s assassination mission is not the only threat aimed at Sato Shinichi. The fallout carries into Episode 2, where a shootout, a wounded bystander and So-ran’s reaction deepen the mystery around the characters’ shared past.
Why the cake-delivery disguise changes the story
The first thing that makes the scene work is its ordinary setup. A cake delivery looks harmless in a house where political guests have gathered. That everyday detail gives the gunman a believable way to approach his target before the dinner turns into a hostage situation. Ga-kyeong is caught in the middle, and the assassin orders her to lead him to Sato Shinichi.
According to episode coverage, the deliveryman is Geum Seok-jung, portrayed by Kam Woo-sung. His arrival adds a second assassination plot to the operation already involving Yoo So-ran and Yoo Philip. Instead of a single plan going wrong, the characters are suddenly dealing with overlapping motives and a threat whose personal connections are not yet clear. Maeil Business Newspaper’s episode report describes the disguised gunman taking Ga-kyeong hostage and the premiere ending on a tense standoff.
Episode 2 turns a hostage scene into a wider conspiracy
The consequences become clearer in Episode 2. The gunman’s attempt to reach Shinichi escalates into a shootout with Sato Hideo. In the confusion, Suzuki is shot, and Seok-jung escapes after So-ran recognizes him. That moment matters because it changes the question from “Who is attacking Shinichi?” to “What history connects these people, and why has it surfaced now?”
Hideo’s role is especially complicated. He is both part of the colonial administration’s inner circle and a person who can read Ga-kyeong’s warning when she quietly signals that an assassination is underway. The show uses that split position to make the action scene do more than deliver a burst of suspense: it tests whether he will act on what he sees or on what he has been taught to believe.
The most important clue is So-ran’s reaction
The gunfire is the obvious turning point, but So-ran’s response is the scene’s emotional clue. Her recognition of Seok-jung suggests a personal history that the assassination plot has kept hidden. Episode 2 later connects the assassin to So-ran’s tragic past, reframing him from a mysterious intruder into someone whose presence could destabilize her entire mission.
This is where the episode earns its title-worthy twist. The scene is not simply about whether Shinichi survives. It is about how one failed attack exposes the fragile cover stories holding the characters together. So-ran’s mission, Philip’s public identity as a journalist and Ga-kyeong’s improvised role in the household all become harder to keep separate.
Hideo and Ga-kyeong are now tied together by the same secret
Ga-kyeong is not a trained operative who controls every variable. She is a resourceful pickpocket who has stumbled into a high-stakes political operation. Her decision to signal Hideo in English gives him information that others at the scene do not have, but it also puts both of them under suspicion. He has reason to distrust her because she previously stole his wallet; she has reason to distrust the system he represents.
The tension works because neither character can safely explain everything. Ga-kyeong needs to stay alive without exposing her new connection to the independence movement. Hideo must decide whether her warning deserves more weight than his suspicion. Their uneasy connection is therefore not a simple romantic misunderstanding; it is built into the spy plot itself.

What the scene means for the next episodes
The attack leaves three questions hanging over the story: how far Seok-jung will go to reach Shinichi, what So-ran will do now that her past has resurfaced, and whether Hideo will continue to protect Ga-kyeong when doing so could expose his own divided loyalties. Those questions are stronger than a simple cliffhanger because each one is tied to a different kind of risk—political, personal and emotional.
The scene also sets up the drama’s central idea: in a world built on disguises, a person’s public role rarely tells the whole story. A cake deliveryman can be an assassin, a pickpocket can become an informant, and an interpreter can be caught between the language he speaks and the side he is expected to serve.
