TRANSMIGRATION #1: Transmigrated As The Villain

Athanasia Zerafi was a powerful secret agent and a former asssassin in her world. When she was given a mission to protect an author of a famous novel whom she hates its main character, she unluckily died in the hands of fate-or was it really just because of fate? Was it really fate's doing?

After the moment that feels like a dream, she woke up realizing she's indeed living inside the villainess' body who's destined to die.
