This is a zombie-ish series featuring two mature leads. The female lead is an anti-terrorist specialist, and the male lead is a police officer. They undeniably make the best partners when it comes to a zombie-themed storyline. In this narrative, there exists a drug capable of turning people into zombies. The unique twist is that these individuals revert to their normal selves after a certain period. This concept evokes a reminiscent vibe of "All of Us Are Dead," but instead of devouring people, they consume blood like vampires.

Our two leads embark on an investigation within a locked-down apartment, confronting a multitude of annoying characters. One aspect I adore about this series is the undeniable chemistry between the leads and their badass actions. Despite their competence, they are not without flaws. I criticize their actions due to their adult nature and the demands of their work. However, one aspect I find irksome, possibly owing to the writer's oversight, is the recurring tendency not to run upon encountering blood. Additionally, there's a scene where the female lead inexplicably opens a truck full of zombies, a move that seems illogical.

Nevertheless, what stands out is the intelligence of the characters, especially the male lead, who is both capable and smart. While the female lead has her flaws, her badassery shines through.
