Synopsis：One lab error. One sham marriage. One secret that rewrites their lives. Ella only wanted a child, but a fertility clinic mix-up leaves her pregnant with the heir of Dominic Moon—the most powerful Alpha in the nation. He needs a Luna to win his campaign. She needs the protection only he can offer. They sign a marriage contract. But between assassination plots, a vengeful ex‑wife, and enemies closing in, the line between arrangement and reality quickly disappears. And the crescent moon birthmark on Ella’s skin hides a truth neither of them ever imagined—some destinies can’t be bargained for.
