Orphaned young and worked to death in my first life, I woke up reincarnated inside a novel.

Unfortunately, I became a doomed extra, a disposable spy sent by the cruel Fause Duchy to infiltrate Duke Kronst by pretending to be his fake daughter.
Knowing the story, I choose betrayal… I’ll side with the future villain, help him find his real family, and secure his protection in return.

This time, I’ll rewrite fate and claim my own happiness.
