Clinic nurse Su Tang and anesthesiologist Lu Yan fell in love for two years. A misunderstanding led her to believe he did not want children, so she kept her pregnancy a secret and left quietly, enduring eight months of pregnancy alone. At 36 weeks, Su Tang's water broke, and she was rushed to the emergency room, unexpectedly discovering that the anesthesiologist in charge was none other than Lu Yan. Their newborn daughter looked just like him, unraveling the truth of the past misunderstanding—Lu Yan had originally only been advising his cousin to raise more cats. Having searched bitterly for Su Tang for half of a year, he took the initiative to shoulder his responsibility, and their elders mediated between them. The two unknotted their hearts, learned to be honest with each other, and raised their daughter Lu Nianjiang together, living together to build a warm and complete small family.
