Ye Fanxing, a senior high school girl, was unexpectedly reborn on the eve of the college entrance examination. She was originally a top student at the Junior Experimental Middle School in H City. She had excellent grades and attracted much attention. Ye Fanxing and Shen Yan grew up together and were inseparable playmates. Unfortunately, Ye Fanxing's father died in a car accident early in his life, leaving her and her mother in poor health. Shen Yan's father has always taken good care of Ye Fanxing's mother and daughter. Therefore, Ye Fanxing and Shen Yan have spent time in the same kindergarten, elementary school, junior high school and high school since childhood. The two are a match made in heaven in the eyes of everyone, and their academic performance has always been among the best.
They had agreed to enter Beijing University together and pursue higher academic goals together. However, everything began to change since a girl named Lin Qiange transferred to their class in their senior year of high school. Lin Qiange always seems to be able to easily attract Shen Yan's attention. Whenever she encounters difficulties or needs help, Shen Yan always leaves Ye Fanxing behind to take care of Lin Qiange without hesitation.
Stimulated by Lin Qiange, Ye Fanxing felt extremely lost and desperate, and finally chose to commit suicide by cutting his wrists. When she was filled with regret, she called Shen Yan, hoping to get his comfort and help. However, it was Lin Qiange who answered the phone. Not only did she not lend a helping hand, she instead told Ye Fanxing that her car accident was not an accident, but someone did it deliberately. This series of blows and betrayals made Ye Fanxing determined to change his destiny after his rebirth and never let tragedy happen again.
