Damien Ashford was born to inherit an empire. Emilia Hart was never meant to be part of it. As children, they were inseparable. While Emilia’s mother worked as the Ashfords’ housekeeper, Damien and Emilia hid in the mansion’s corners, building a friendship no one was supposed to see. Then Damien’s jealous stepmother framed Emilia’s mother for a crime she didn’t commit. Mother and daughter were thrown out with nothing. Before they left, Damien’s father made one promise: Emilia would get a full scholarship to the country’s most elite academy, on one condition, she had to pretend she never knew the Ashfords. Years later, Damien is the ruthless billionaire CEO everyone fears. His inheritance comes with one impossible demand: marry, have a child, and prove he’s not the man his father was. Emilia has degrees, grit, and debt, but no connections. Even entry-level jobs at top firms are closed to her. Meanwhile, Damien’s stepmother schemes to force him into marrying one of her chosen socialites to steal the empire. One rainy night changes everything. After Damien saves Emilia from a stalker, he makes her an offer: One year. One fake marriage. No strings. At the end, she gets one million dollars and a clean annulment. They draft a contract to keep feelings out of it. Then Emilia adds the last clause. The Billion-Dollar Clause: If either of us falls in love, we owe the other one billion dollars. Damien laughs. Easy. What he doesn’t know is Emilia has loved him since they were kids. What she doesn’t know is he fell first. Some contracts are meant to be broken. This one could cost them everything.
