On the first day of school, Lin Xingchen was coldly warned by student council president Gu Huaizhi: "You're blocking my light." Then she discovered that this arrogant campus heartthrob was actually her fiance, and he had amnesia, too. To pay off her grandmother's debts, she signed a dating contract and played the part of a loving couple at school. He fed her, stood up for her, and stayed by her side all night when she had a fever. She kept reminding herself that it was all an act, never knowing that his amnesia was fake. Winning her back for real was the true plan.
