Veronica Monet, a brilliant top PR specialist from modern New York, dies of overwork and transmigrates into this medieval‑style world as Countess Veronica Roland. She is trapped in an unhappy marriage with arrogant Count Arthur Roland, imperial military commander. After two years away at war, Arthur returns home, bringing Elisa, a seemingly gentle wartime healer who claims to have saved his life. Eager to annul her marriage, reclaim her dowry and live freely, Veronica repeatedly seeks a divorce, yet court customs and imperial power stand in her way.
By chance in a cathedral, she stumbles upon Emperor Alexios Valois’ top‑secret agony: the feared tyrant suffers a deadly dark‑magic blood curse held at bay by a parasitic Blood‑Devouring Worm. During a scuffle, Veronica’s blood touches the worm, forging an irreversible life‑and‑death bond. From then on, she must visit the palace to offer her blood on every new moon and full moon.
Initially, cold, tormented Alexios regards Veronica only as a living cure. However, he is gradually drawn to her sharp wit, fearless spirit and modern‑minded way of handling crises. Veronica struggles against Arthur’s possessiveness, Elisa’s manipulative schemes and the biased Empress‑Dowager’s repeated humiliations, with her loyal maid Vivian at her side.
