On the night of their engagement in her previous life, her fiancé and her mistress conspired to steal her property and also killed her.
Reborn in this life, she wakes up among the dead.
This world was unfamiliar to her, but with the help of a noble man, she became a master and allowed her to practice immortality along the way.
But one day, she was told that she might be the key to saving the world. She thought, since she had already died, there was nothing to be afraid of, so she happily accepted the task.
But who knows, the beautiful man she meets on the way is very attentive to her, which catches her off guard. Should she love bravely or run away?
Her bizarre life experience and bloodthirsty fear made her understand that she was an outlier in the three realms and an abandoned person from the three realms.
