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. Kate intervenes, recognizes Sophie and Jack as family, and tells Caleb to marry Jack's mother, not realizing he's already falling for Sophie. 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.

Mark Dalton engaged in charity work and financially supported Carla Fulton, who was in poverty. Carla mistakenly believed that she held a special place in Mark's heart and gradually became arrogant. Five years later, after graduating from university, Carla, in an attempt to show off, lied that Mark was her brother and brought her classmates to intern at his company. Mark, busy with the company's IPO, delegated the task of arranging the internships to his subordinates. The subordinates did not dare to stop her, allowing her to act recklessly within the company. She fired the technical team and declared herself the chairperson. When Mark was negotiating a partnership with Saturn Group, Carla's outrageous behavior caused the deal to fall through, and Mark was so furious that he fainted and was hospitalized. Carla continued her reckless actions, pushing the company to the brink of bankruptcy, and even planned to sell it. After Mark regained consciousness, he exposed her lies. Resentful, Carla teamed up with a rival company to sabotage Mark's projects. In the end, Mark uncovered the conspiracy, Carla was arrested, and the company successfully went public with the support of Saturn Group.
