Workplace devil Chloe has a wild one-night stand with a mysterious male model at a masquerade ball and ends up pregnant. To satisfy the marriage clause of her family trust fund, she signs a one-year contract marriage with her business archrival Liam.
By day, they battle ruthlessly in cutthroat corporate wars. By night, they put on a fake married act under the same roof. Liam sneers mockingly, calling her unborn child the offspring of some random fool, vowing to hunt down the man who hurt her.
But as they live together, hidden feelings begin to grow. Then the explosive truth comes out: that mysterious man from the masquerade is none other than Liam himself. When he realizes he is the so-called "fool", all his arrogance crumbles to dust. He embarks on a desperate journey to protect his wife, defeat outside troublemakers, and burn in the dramatic wife-chasing redemption arc.
