On the day Li Xiu received the certificate, he was betrayed by his fiancée Liu Ruyan, who broke the appointment to take care of Bai Yueguang and Xiao Muchen. Unexpectedly, he faked a marriage with Fu Xiuyu, the president of the Fu Group, and counterattacked all the way with the wealth and hacking skills rewarded by the system: he was quickly promoted in the Fu Group, defeated Liu Ruyan and his family's entanglement, and exposed Xiao Muchen's hypocrisy. In the process, Li Xiu and Fu Xiuyu gradually developed a true love from their contract marriage, and also gained recognition from the Fu family, resolving family tests and business crises. In the end, Li Xiu completely got rid of the past, and he and Fu Xiuyu became successful. They had a good career and love, and severely trampled on those who once despised him.
