I'll never leave

Alice, an seemingly ordinary human, finds her life irrevocably changed when she falls deeply in love with Shawn, a captivating being who is half-vampire and half-demon. Their passionate connection leads to a pivotal moment where Alice's hidden powers awaken, revealing her true identity: she is the long-lost Demon Queen, Nyx. This revelation, however, comes with a dark side; her newfound demonic nature amplifies her negative emotions, causing her to lash out and even harm those she cares about.
Struggling with her dual nature, Alice is drawn to a mysterious, ancient castle, her maternal home, where she reunites with her mother, Zhou—a powerful witch. Zhou reveals Alice's true lineage as the daughter of a demon king and a witch queen, explaining that her memories were suppressed and her powers sealed to protect her from vengeful witches. The magical ritual performed to save her life after an attack, however, had a significant cost, affecting her father's memories and linking his return to her loss of innocence.
Under her mother's guidance, Alice trains to control her witch powers, but mastering her demonic side requires a journey to Hell. There, she fully embraces her role as Queen Nyx, ruling with a firm hand and even encountering her demon king father, Drexel (who is also Lucifer's nephew). As Nyx, she exhibits formidable power and a ruthless streak, leading to a tense confrontation with Shawn, her love, who tries to bring her back to her "Alice" self. Their tumultuous relationship deepens as they navigate her volatile powers and his attempts to keep her grounded. The story delves into Alice's struggle to balance her human heart with her demonic destiny, her relationships with both her birth family and Shawn, and the challenges of her reign in Hell. Ultimately, through their trials and unwavering love, Alice and Shawn succeed in forging an unprecedented peace between the vampire, demon, and witch realms, uniting their disparate worlds.
