Xia Yuyan, a 27-year-old girl who came from the United States, was robbed by a gang of speedsters as soon as she got off the plane. She suffered a head injury in a car accident, resulting in temporary blindness and temporary amnesia. After being admitted to the Affiliated Hospital of J University, the attending physician An He gradually fell in love with her and actively helped her restore her memory... An and her best friend and colleague Yang Xi had a childhood sweetheart and first love, Qiao Muxia. In the third year of junior high school, he was taken to the United States due to a sudden family change and was never heard from again. However, Yang Xi... He couldn't forget it. After waiting for 12 years, he suddenly met Xia Yuyan, who looked like Mu Xia. Although Yuyan's family clearly stated Xia Yuyan's identity and stated that she had lived in the United States since she was a child, Yang Xi always felt that Yuyan was Mu Xia, so he began to take Yuyan to search for memories.
When Yu Yan finally regained her memory and remembered that she was Mu Xia, Yang Xi decided to give up Yu Yan and marry Zhao Jier, who had been following him, because he could not prove that Yu Yan was Mu Xia and for the sake of his friend An He. In order not to disturb Yang Xi's peaceful life, Mu Xia pretended that she had not recovered her memory and flew back to the United States. Zhao Jinger did not attend the wedding after discovering that Yu Yan was Qiao Muxia, and left a letter asking Yang Xi to go to the United States to find Qiao Muxia. After knowing Mu Xia's true identity, An He also gave up his feelings for Mu Xia and supported Yang Xi to go to the United States to find Mu Xia...
