Qiao Ran, the ignored daughter of the Qiao family, has been practicing medicine away from home for many years. One day, she saves Lin Yue, the eldest son of the Lin family, in an accident, but in the process, she gets injured. Because the Qiao family refuses to treat her, she misses the best chance for rescue. The excessive blood loss leads to brain hypoxia, causing her to lose the memories from the time of the injury. Three months later, a recovered Lin Yue comes to find his benefactor to express his gratitude, only to be deceived by Qiao Shishi, the second daughter of the Qiao family, who pretends to be the one he saved and becomes his fiancée. However, as Lin Yue spends more time with her, he gradually realizes that it is Qiao Ran who is the person he has been looking for.
