Nora, a blood pharmacist, hoped that her husband could pay the final balance and take her and their son out of the bottom life. However, her husband Arthur was cruelly killed like an ant by vampire noble Seraphina. To uncover the truth, Nora endured extreme pain to rebuild her pure blood constitution and sneaked into Blackwood Manor under a false identity. She wandered between the manor lord Julian and the favored Seraphina, suffering humiliation, only to find that her husband faked his death in collusion with Seraphina. Nora began to collect evidence of their betrayal and cooperated with Julian. In this hunting game, she borrowed strength from others, used the blood servant Ada to intensify conflicts, and forced Arthur to show up. On the day of the blood moon sacrifice, she exposed all the lies and had the two traitors nailed on the tower to perish in the sunlight. Finally, Nora abandoned noble fame, returned to the streets with her son, and saved countless people, completing her transformation from a vengeful avenger to a benevolent healer.
