What did Park Jinyoung mean by “1,000 out of 100”?
At the drama’s September 29 press conference, Park Jinyoung was asked about acting opposite Kim You-jung in the romance storyline. He answered that their chemistry deserved “1,000” out of a possible 100 points, adding that director Yoo In-sik often beamed during their romantic scenes. The exaggerated score was playful, but the explanation behind it gave the quote more substance than a standard promotional sound bite.
According to ChosunBiz, Kim You-jung also said working with Park felt comfortable and fun. She described the relationship as one in which the characters grow by understanding each other—an important distinction for a story built around hidden identities and conflicting loyalties.
Why their characters need more than instant attraction
100 Days of Deception is set in Japanese-occupied Korea in 1932. Kim You-jung plays Lee Ga-kyung, a skilled pickpocket recruited into an undercover mission for the independence movement. Park Jinyoung plays Kim Tae-woong, also known as Sato Hideo, a multilingual interpreter adopted by a powerful official in the colonial administration.
Their connection begins in suspicion rather than trust. Ga-kyung is concealing her mission, while Hideo’s identity and loyalties are complicated by the name and position he has been given. That setup gives the romance a dramatic problem: each character must decide how much to reveal, what to believe, and whether affection can survive the truth.
Park Jinyoung’s restrained approach helps the tension
Park has described trying not to overstate Hideo’s complicated emotions. ChosunBiz reports that he focused on controlled movements and expressions, partly because the character has been shaped by a difficult relationship with his adoptive father. That restraint can make a romantic scene more revealing: a pause, a guarded look, or a shift in posture may communicate what the character cannot safely say.
For a spy romance, this style is useful. Hideo works in an environment where language can conceal as much as it explains. A performance that leaves some feelings unreadable mirrors the uncertainty at the center of the plot and allows viewers to question whether a gesture signals attraction, suspicion, or self-protection.
Kim You-jung’s perspective: a romance built through growth
Kim’s comments add balance to Park’s joke. Rather than describing chemistry as simply instant sparks, she emphasized that both characters have their own backgrounds and that the relationship develops as they understand one another. Ga-kyung is not merely a romantic lead waiting for Hideo to change: she has a mission, ambitions, and choices that can put her in danger.
The pairing will depend on whether the series lets both characters remain complicated. Viewers should be able to see why they are drawn together without forgetting that their secrets can put other people at risk. The 100-day deadline gives every new moment of trust a cost: the closer they become, the harder it may be to separate personal feeling from the mission.
Behind-the-scenes footage offers another clue
Soompi reported that the leads laughed during poster filming, with Park helping brush dust from Kim’s clothing and the pair joking while trying poses. Those moments do not prove how a scripted romance will play on screen, but they show a relaxed working atmosphere that can help performers experiment with timing and reactions.

Is their chemistry really the drama’s biggest strength?
It is too early to treat one quote or a press-conference moment as proof that the romance will satisfy every viewer. The more meaningful test is whether the show makes the characters’ trust feel earned. A convincing spy romance must balance attraction with stakes and let the historical setting shape decisions rather than function as decoration.
Still, the “1,000 out of 100” line points to the collaborative side of acting. Chemistry is not only about looking compatible in a poster; it also comes from listening, reacting, and giving a scene partner room to build a moment. If the series carries that ease into its more painful scenes, the central relationship could become one of its most compelling elements.
