The story is about Rehan, a cursed vampire and Priya, a half-fairy hybrid.
Rehan, a cursed vampire living a human-like existence, harbors an aversion to light and an unfulfilled yearning for love. Priya, a half-fairy hybrid with extraordinary abilities, crosses paths with him in Mussoorie. Rehan seeks answers about his supernatural origins, while Priya searches for her missing parents. Though initially drawn to each other, both conceal their true identities. Unbeknownst to Priya, the Khurana family she resides with are her biological relatives. Her estranged mother Rageshwari, aware of their intertwined destinies, schemes to keep them apart, fearing Rehan's potential danger.
As their connection deepens, Priya discovers Rageshwari is her mother and Farishta her father but chooses silence to protect Rageshwari's reputation. Later, witnessing Rehan's vampiric form, Priya survives his unintended attack, protected by an unknown force. During a full moon, Rehan fully transforms into the Aadishaat (a superior vampire entity), coinciding with Swati and Arnav's engagement. When Priya plans to expose him, Rageshwari imprisons her, fearing Rehan's escalation. Amidst this chaos, Soumya and Mohit's engagement is announced, but Mohit confesses his love for Priya, prompting Rehan's confrontation.
Rehan apologizes for frightening Priya, professes loyalty to his sister Soumya, and devises a ruse: a fake engagement to deter Mohit. Priya agrees, demanding Rehan spare her family. However, under duress from Ajnabi, who kidnaps Rageshwari, Priya falsely claims love for Mohit, enraging Rehan. He takes her to a forest, kills her, and ascends to full Aadishaat power, erasing his memory in the process. Rageshwari resurrects Priya using antidotes derived from Shivanya, Shivangi, Bela, Brinda, and Bani, transforming Priya into a naagin (serpent-shifter) rivaling Rehan’s strength.
Seeking vengeance, Priya returns, manipulates Mohit into a marriage, and disrupts Soumya's wedding. Rehan imprisons Mohit, impersonates him, and unknowingly marries Priya in disguise. The Khuranas reluctantly accept her presence. Meanwhile, Pam murders Rageshwari and Soumya. After Soumya's death, Pam attempts to kill Rehan for his powers, but Priya intervenes. United, they defeat Pam. Choosing forgiveness, Rehan and Priya reconcile, vowing to rebuild their bond.
