Female student Su Xiaoman returned to China for development, but on the way back home, she fell in love at first sight with the IT genius Wu Yue who was carrying hatred. The seeds of love and revenge sprouted in their hearts at the same time. At the same time, the highly anticipated brain data ushered in a new season of recruitment. Su Xiaoman accidentally participated in the reality show "Geek Maniac" and was determined to develop an APP independently. Wu Yue also entered the brain data as he wished and became colleagues with Su Xiaoman, the second-generation rich Lin Shaoting, and the technical geek Zhang Jiang.
