Lin Wei (the heroine), a girl from the countryside, has been suffering from the pain of not being favored and being dependent on others since she was a child, but she was admitted to the Chemistry Department of Beijing University with her perseverance. During the military training at the university, she fainted due to lack of physical strength, and was rescued by Wei Ran (the male protagonist), a sunny school boy in the same department, and the two became friends. Wei Ran's gentle protection and unremitting pursuit broke Lin Wei's inner inferiority barrier. Even with the obstruction of school beauty Qin Lan and the gap in status, they still walked through the romantic college years together. After graduation, the two joined the same pharmaceutical company. Just when happiness was within easy reach, Wei Ran's family forcibly separated them because of their family differences, and Wei Ran was forced to go to the United States. Lin Wei turned his grief into motivation and focused on the research and development of new drugs. During this period, he rejected the affectionate confession of his alumnus Li Ze (second male). Three years later, Wei Ran went through many twists and turns to convince his family and returned with Lin Wei's promise to see the aurora. The two overcame many obstacles and made a lifelong vow under the aurora, continuing a warm love song that began in youth and ended in ecstasy.
