By coincidence, they meet again when she's humiliated by her ex-husband; he stands up for her, leading to a flash marriage. He conceals his identity as a CEO and assists her in every way possible. He helps her through obstacles on the path to happiness, but things take a surprising turn when she discovers he is the man from her one-night stand years ago, making him the biological father of her child.
