Falling in love with a vampire is my destiny

This world is not just about humans, God, and Satan; it is not just about heaven, earth, or hell.

There is also a vast expanse—the realm of vampires.

The fall of vampires is so profound that even God cannot redeem them.

He is the ruler of the entire realm, while she is merely an ordinary human with a tragic background.

Because of an ancient book, she was forced to sign an irreversible contract—to make him fall in love with her. But this is merely the beginning of evil.
