Dr. Seo Hana spent her life studying monsters.
As a criminal psychologist with photographic memory, she could recall every detail of every case she had ever encountered. Violence, trauma, manipulation—she understood the darkest corners of the human mind.
Then she died.
When she wakes again, she finds herself reborn in the world of a historical novel she once read, inside the body of Lady Seorin, a noblewoman doomed to die.
The story she remembers is simple.
A brilliant Crown Prince rises to power.
A saintly heroine becomes his empress.
Together, they save the empire.
But that was never the whole story.
Because in the shadows of that shining narrative exists another figure.
An illegitimate prince feared throughout the empire.
A weapon of war.
A destroyer of noble houses.
A monster even loyal generals dread.
And eventually, the man who will rebel against the Crown Prince and plunge the empire into chaos.
The final villain.
The problem is…
Seo Hana remembers the novel clearly.
Except for one thing.
Despite her perfect memory, the most important details about that villain prince are missing.
Why did he rebel?
What pushed him to destroy the empire?
And why does the so-called saintly heroine suddenly feel far more dangerous than the book ever suggested?
With a loving father, a warm younger sister she refuses to lose, and a future already stained with blood, Hana decides to change the story.
Even if it means walking straight into the path of the empire’s greatest monster.
Because sometimes the difference between a villain and a hero…
Is simply who wrote the story first.
