The Su Group went bankrupt, and Su Qingleng, the once unattainable daughter, fell from the altar. In order to pay her father's high medical bills, she was forced to fulfill her childhood engagement and marry Lu Ran, an intern who seemed to be a carefree man but was actually an outstanding medical practitioner. After the marriage, Lu Ran carefully warmed Su Qingleng's frozen heart with sunshine and humor. However, Su Qingleng's arrogance and self-esteem prevented her from accepting the love calmly. In addition, the rich second-generation villain who was jealous of Lu Ran's talent obstructed her, creating a series of misunderstandings about Lu Ran's professional ethics. During a major medical accident incident, Lu Ran held back to protect Su Qingleng, but was misunderstood by Su Qingleng as cowardly and incompetent, and angrily threw out the divorce agreement. Lu Ran was determined to let go, but Su Qingleng later learned the truth, filled with regret, and began a long road to pursue her husband (in the second half, the male protagonist also began to pursue the female protagonist again, and the two sides were extremely involved). In the end, the two of them untied their knots in a life-and-death rescue.
