A low-ranking civil servant suddenly realizes she has been reincarnated inside a novel where a devastating war is about to begin—and people like her are destined to die early.

Knowing the future, she decides to change the story by protecting the crown prince, who is originally meant to die first. By secretly exposing conspiracies and helping eliminate threats, she ends up playing a key role in preventing disaster and quickly rises through the ranks.

Although she insists she’s only trying to survive and eliminate villains, her efficiency and boldness unintentionally make her powerful and respected. People around her start to misinterpret her strict dedication as something more intense—and even a little frightening.

As she continues obsessing over keeping the prince safe at all costs, her overly serious attitude begins to affect those around her in unexpected ways, leading to growing confusion, admiration, and a few strangely flustered reactions she never intended.
