Lin Xi, a "scumbag" in the second year of high school, is actually the forum technology master "Zero". Due to class conflicts, he had a grudge with Jiang Yu, the number one in his grade. In order to raise money for her best friend's grandmother's surgery, she was forced to team up with Jiang Yu to participate in a programming competition. She used her status as a bad student as a cover, but she communicated tacitly with Jiang Yu, the forum moderator "River" online as "Zero". As the competition progressed, Lin Xi's creativity and technology repeatedly shocked Jiangyu, and he gradually discovered that this "student scumbag" overlapped with his online confidant. During the code confrontation, the two tested the disguise and the truth. While uncovering the double-sided life, they also wrote passion and growth in their youth.
