Five years ago, Arthur Astor heartlessly severed the blood oath he had sworn with Elian Norman, casting him aside. Now, five years later, Elian discovers he is not the biological son of the Norman family. With the true heir, Orian, constantly targeting and suppressing him—and his adoptive parents turning a blind eye—Elian decides to leave the Norman household. In search of a livelihood, he applies for a position as a bodyguard to the Duke of Astor, only to realize that the Duke is none other than his former lover, Arthur Astor. It turns out that Arthur’s cold-hearted breakup five years prior was not born of malice, but of a deep-seated vendetta: his mother had been driven to her death by Victoria, Elian’s adoptive mother. As Arthur struggles between his quest for vengeance and his lingering feelings, Elian happens to learn that Arthur already has a child—drawing the two men back into a web of fate and hatred.
