Main Characters and Story Roles
Yoo Bo Na is the character most directly tied to the series’ hidden world. She is described as a married woman working as a killer within a secret organization. That contrast between domestic life and covert work gives the drama its main source of tension.
Kwon Tae Seong provides the opposing perspective. Rather than sharing Bo Na’s secret, he wants to uncover it. The relationship therefore functions as more than a simple romance or family storyline: it is also the route through which the concealed organization may be exposed.
The supporting cast expands the series beyond the central marriage. Lee Dong Jin, Kim Bong Pal, Bae Yun Ok, and Ki Yeong Do are all listed as recurring characters across the 14-episode season. Additional credited roles include O Hyeon Nam, Ko Yeong Gap, Yang Ye Sul, Kwon Se A, Beom Seong Hun, and Ok Seon Ja.
Available information confirms names, credited roles, and the broad premise, but it does not provide full biographies, affiliations, or episode-by-episode arcs for every character.

For viewers deciding whether the series matches their preferences, the genre blend can be read in three ways:
- Action viewers may be drawn to the secret organization and killer premise.
- Drama viewers may prefer the marriage conflict and emotional consequences of deception.
- Thriller viewers may focus on Tae Seong’s effort to discover the truth.
The series should not be reduced to a simple assassin story. Its defining hook is the collision between hidden professional violence and an intimate relationship. That structure gives the cast’s performances particular importance because the central tension depends on what characters know, conceal, or attempt to reveal.
Action Focus
Secret-organization activity, professional danger, and the pressure created by Bo Na’s hidden work.
Drama Focus
A marriage placed under strain when one partner’s identity is not what it appears to be.
Thriller Focus
Investigation, concealed information, and the question of whether Tae Seong can expose the truth.
