Song Yuan, who appears to be an ordinary programmer but is actually a top hacker, was abandoned by his girlfriend of five years, Lin Xueyao, on the eve of his wedding. She turned around and fell into the arms of Bai Yueguang Xiao Nianchen. However, Song Yuan had a relationship with Gu Shiyu, the president of the Gu Group, by chance. In order to deal with the dilemma between his parents and the wedding, Song Yuan proposed a flash marriage to Gu Shiyu, but Gu Shiyu readily agreed because his family was urging them to get married. On the other side, Lin Xueyao was frequently humiliated by Xiao Nianchen. She regretted it endlessly, and eventually ended up being separated from her relatives. Song Yuan and Gu Shiyu advanced and retreated together, overcame all difficulties, and finally achieved a double harvest in career and love, starting a life that truly belonged to each other.
