An ordinary human girl falls deeply in love with a pureblood vampire count and lives with him in secret for three years. When the count suffers fatal injuries from sunlight, the girl drags him to safety, suffering terrible burns in the process. However, a jealous female vampire steals all the glory. She weaves plot after plot to frame the girl, tricking the count into draining her heart’s blood and casting her dying body into the Endless Blood Abyss. At the brink of death, the girl’s pure soul rouses the thousand-year dormant vampire progenitor, who grants her supreme blood power and resurrects her as the Queen of Night. Overwhelmed by crushing remorse once he learns the truth, the count treads the path of blood-thorned torment to seek atonement. Sheltered and treasured by the progenitor, the new night queen eliminates the scheming vampire, rebellious elders and the dark wizard who unleashed the abyss curse, severing the curse’s root. In the end, she rules the whole night realm alongside the progenitor.
