Olivia Chen has spent three years planning the perfect wedding to Marcus Wright, her childhood sweetheart and the man her wealthy family adores. The night before the ceremony, she walks into her fiancé's apartment to surprise him with his favorite homemade dumplings and finds him in bed with her younger sister, Sophia. Heartbroken and humiliated, Olivia flees to a dive bar in a neighborhood she's never been to before. She orders the strongest drink they have and tries to erase the image of her fiancé and sister tangled in sheets that were supposed to be hers. That's where she meets Ethan Kane, a mysterious stranger who looks as miserable as she feels. He's drinking alone in the corner, nursing wounds she doesn't ask about. They talk. They laugh. They drink too much. And when he offers to help her forget for one night, she says yes. What was supposed to be a one-night stand turns into something more complicated when Olivia wakes up the next morning with a marriage certificate on the nightstand and a wedding ring on her finger. She married a complete stranger in a Las Vegas chapel neither of them remembers finding. Olivia's first instinct is to get the marriage annulled immediately. But then her family shows up at her door with news: they've decided to proceed with the wedding to Marcus anyway. Sophia has graciously agreed to step aside. The family's reputation depends on this alliance between the Chen and Wright families. They expect Olivia to swallow her pride, forgive Marcus's infidelity, and marry him as planned. That's when Ethan makes her an offer. Instead of annulling their accidental marriage, they could use it. He needs a wife for six months to secure his inheritance from his late grandmother's estate. She needs protection from her controlling family and a way to destroy Marcus and Sophia's perfect image. They strike a deal. For the next six months, they'll play the perfect married couple in public. What neither of them expects is how convincing their fake relationship becomes. Or how falling for your accidental husband might be the best mistake Olivia ever made.
