Valen, a centuries-old vampire disguised as a human, has lived a detached, emotionless life-until he meets you, a human woman who awakens a dark obsession within him. However, you are married to Marco and surrounded by a loving family. Enraged by your happiness with another, Valen meticulously kills your husband and family, isolating you completely.

Using dark magic, Valen erases your memory, and when you wake up, he convinces you that he is your husband. Though you initially trust him, flashes of your true past begin to surface, leading to a battle between your forgotten identity and Valen's possessive hold on you.
