A young woman named Martina has a deep and genuine love for books, so much so that she has managed to read every single volume available in her local town. Her thirst for knowledge cannot be satisfied by this achievement alone, as she learns of an undiscovered library full of untold stories hidden within the royal palace. Determined to gain access to this treasure trove, she sets her sights on an unusual career path that will get her through the palace gates. She decides to become a government official.

To achieve her goal, Martina must first pass an incredibly difficult civil service examination. She discovers that she possesses a secret weapon for this task: a perfect or photographic memory that allows her to recall every single word she has ever read. Using this extraordinary ability, she takes the challenging exam and achieves a perfect score, securing her position within the kingdom's bureaucracy. She is subsequently assigned to work in the Political Affairs Department.

While her powerful memory initially surprises her new colleagues, Martina's story quickly moves beyond simple administrative work. The peaceful setting of the royal palace and the surrounding kingdom is suddenly threatened by the appearance of an unnatural monster. This event marks a major turning point, transforming Martina's quest for books into a struggle for survival. Armed only with the vast knowledge she has accumulated from countless texts, she must now find a way to deal with this supernatural threat and protect the nation she now serves.
