When Gilberto was struggling with poverty, he proposed to Yvette, drafting a bold agreement that if he ever betrayed her, he would leave everything behind. Five years later, now the chairman of a successful pharmaceutical company, Gilberto's life seemed perfect. But Yvette, pregnant with twins, couldn't ignore the nagging feeling when she saw him behaving intimately with his business partner, Freya. Unable to shake the suspicion, Yvette followed her husband and uncovered the heartbreaking truth—Gilberto had traveled miles just to cheat with Freya over a casual barbecue. On their return flight, disaster struck. The plane's engine malfunctioned, forcing an emergency landing. In the chaos, Yvette lost her babies, but Gilberto had no idea she was on that same plane. As Yvette was rushed to the hospital, Gilberto, frantic to see her, arrived only to find a divorce agreement waiting for him. Consumed by regret, he did everything he could to win her back, but Yvette had already moved on. She no longer loved him.
Eight years after a one-night stand, Sophie Archer raises son Jack alone until he's diagnosed with leukemia requiring a rare blood-type donor. Doctors suggest a million-dollar imported medicine to buy time. While struggling financially, Sophie becomes Caleb Johnson's secretary, unaware he's Jack's father. Meanwhile, Caleb and his grandmother Kate meet Jack by chance and confirm paternity through DNA testing. As Sophie and Caleb develop feelings and she becomes pregnant again after another encounter, Sophie saves enough for Jack's treatment, only for rival Chloe Bradford to destroy the medicine.

When Caleb discovers Sophie is Jack's mother, they commit to each other. At their wedding, Sophie reveals she has no blood relation to the Archers, and learns she's actually the biological daughter of the Bradfords couple, whom she refuses to forgive. The story ends with Sophie giving birth to twins and living happily with Caleb, Jack, Kate and their growing family.
