the phoenix girl and her vampire lover.

In the Heavenly Realm, Princess Aeloria, the only daughter of the Heavenly Emperor, was admired for her beauty, wisdom, and extraordinary power. Destined to inherit a glorious future, she lived a life many could only dream of. But fate had other plans. After a mysterious incident during her ascension, Aeloria's soul descended into another world and was reborn as a phoenix in the Vampire Realm. Her birth brought joy to the powerful General's Mansion. For generations, they had waited for the arrival of a child blessed with immense power—a child destined to change the future of their world. Eighteen years later, curious about life beyond the Vampire Realm, Aeloria concealed her true appearance and identity, taking the name Kassandra. Disguised as an ordinary human girl, she journeyed to the Human Realm in search of freedom, adventure, and answers she never knew she needed. Along the way, she met Larissa, a warm-hearted young woman who quickly became her closest friend and sworn sister. Determined to experience life as a normal human, Kassandra joined Lee Empire, one of the most powerful corporations in the world. There, she crossed paths with Ryan Lee. Young, handsome, and unbelievably successful, Ryan was admired by many and feared by even more. Known as the ruthless devil of the business world, he kept everyone at a distance behind a wall of cold indifference. Yet Kassandra was different. Unlike everyone else, she neither feared him nor sought to gain his favor. As the days passed, an unexpected bond began to form between them. But not everyone was willing to watch their relationship grow. Jessica Hudson, Ryan's fiancée, viewed Kassandra as a threat and became determined to remove her from Ryan's life. What begins as jealousy soon turns into a dangerous obsession. However, Jessica has no idea that the seemingly ordinary girl she wishes to destroy is hiding powers beyond imagination. As secrets buried for centuries begin to surface, Kassandra discovers that Ryan is hiding truths of his own. Who is Ryan Lee? Why is he living in the Human Realm? Is he truly human? Or is he connected to the Vampire Realm, the Heavenly Realm, or something even more mysterious? As love, betrayal, ancient enemies, and hidden destinies collide, Kassandra and Ryan must uncover the truth behind their identities before darkness consumes everything they hold dear. A journey filled with romance, power, secrets, sacrifice, and destiny awaits.
