Shen Luning, a painfully shy woman who has never dated anyone, receives an ultimatum from her mother: bring a boyfriend home, or she’ll post a marriage notice at her school.
In desperation, she signs a three-month dating contract with Lu Zhiheng, the most aloof and unapproachable campus heartthrob.
She thinks it’s just a mutually beneficial arrangement. Only later does she realize she’s the only one who’s fallen into character, he never stopped playing his part.
