In 2037, Qi Yang is betrayed by his brother Su Ming. His beloved Tian Wei, his childhood sweetheart, and his longtime friends Luo Bing and Luo Shuang all meet tragic ends, and he dies with hatred in his heart. By chance, he is reborn on the first day of the 2017 school year at Jiangcheng Vocational School and binds himself to the “Misaligned Timelines System.” He learns that 15 key misalignment events are hidden in the current timeline. Worse still, a reborn person possesses a “World-Ending System” and is targeting a subsidiary timeline, seeking to destroy the main timeline once and for all. Qi Yang doesn't yet know that person is Su Ming.
The System's missions are to correct the misalignments, expose the saboteur, and protect those around him. On his first day of school, Qi Yang uses the System and his memories of his previous life to save Tian Wei from being harassed, taking the first step toward changing their fate. From then on, he carefully plots his way through vocational school, using his foresight to show off and face-slap troublemakers. As he and Tian Wei weather hardships together, their feelings grow, though their romance soon turns angsty. Later, he will also meet the genius hacker Zheng Shanshan, the billionaire's daughter Dao Yilan, corporate president Li Keke, and the well-connected policewoman Deng Jia. Together, they will face the coming crises. In the end, can Qi Yang uncover Su Ming's conspiracy, correct every misalignment, protect those he cares about, and make his second life a happy one?
