On the first day of military training for Yunya High School freshmen in 2004, Xia Yiwei's disappearance shocked the whole school. My mother is dead, my father doesn't love me, my grandpa doesn't love me, my stepmother treats me harshly...
Because of two identical MP4s and Qiao Xue's calculations, Song Yu and Yao Ruolin became the Iron Triad. Xia Yiwei's math scores were always ranked last in the entire grade and she was a joke to the whole school. However, Luo Xiaotian, the talented boy who scored perfect marks on the math test in his grade, agreed to give her extra lessons. The eldest son of the Tong family, who returned to China for a while, was also deeply attracted by Xia Yiwei's natural temperament... So, the indifferent genius science boy, the proud and perverse rich daughter, and the rich young man who was spoiled by his family and became lawless, slowly approached each other in the youthful season.
Everything should have gone as it should, but what I didn't expect was that Xia Yiwei's first love had a car accident.
At this point, everyone's fate begins to go off the rails...
