Reborn in his senior year of high school, Chen Huaian unexpectedly captures footage of Lin Nianchu, the aloof school beauty, stealing bread from his family's supermarket. In his previous life, he let her leave, only to learn the next day that she had died in a car accident. This time, he forces her to stay, using the recording as leverage to gradually enter her impoverished yet resilient life. From insisting that she accept a schoolbag and stationery to arranging for her to work part-time at the supermarket, he gradually uncovers the secrets of how she quietly helped him with classroom duties and voted for him. The young man who once had eyes only for his unattainable first love finally awakens, begins studying with all his might, and vows to protect the kindhearted girl who has been plagued by misfortune but never lost her goodness.
