Secretary Zhong Yi and her boss, Jin Chen, had an accidental one-night stand after drinking. Afterward, she took expired emergency contraception and unexpectedly became pregnant. Zhong Yi wanted to handle it alone, but Jin Chen stopped her, and the two registered their marriage. Zhong Yi had a difficult background: her mother was once deceived by her biological father, Bai Beishan, and saddled with huge debts. Her ex-boyfriend and half-sister, Bai Jinse, appeared successively to create twists and turns. Online malicious rumors severely damaged Zhong Yi, but Jin Chen protected his wife with all his might, joining forces with Zhong Yi and her mother to expose Bai Beishan's commercial fraud and years of misdeeds. After going through misunderstandings and hardships, Jiang Yi let go of his obsession and reconciled with Bai Jinse. Zhong Yi successfully finished her MBA, and the two publicly announced their status as husband and wife, embracing a stable and happy life hand in hand.
