Reborn through a twist of fate, Su Zelin returns to his past just before the college entrance exam—determined to change his regrettable treatment of Qin Shiqing, his childhood sweetheart. Haunted by the fear of repeating his past mistakes and unable to trust his own jerk nature, he hatches a scheme: providing her with exam answers to guarantee her admission to Tsinghua or Peking University while he enrolls elsewhere. In his mind, creating distance between them will protect her from his worst impulses. The plan seems foolproof until reality strikes two months later. Su Zelin's careful strategy crumbles when he discovers Qin Shiqing's acceptance letter—not from Tsinghua or Peking University, but from Zhejiang University. Frustration boils over as he demands: "Qin Shiqing, why didn't you get into Tsinghua or Peking University?" Her embarrassed confession cuts through his irritation: "I misjudged my performance." What was supposed to be a painless separation has become anything but.
