Ningxia (Jiang Mengjie) uses the pseudonym "Xiao Hongdou" on the Internet and meets a man named "Shudong". The two chat very speculatively and develop a sincere friendship. Xiao Hongdou also becomes Shudong's savior by chance. In fact, Shudong's true identity is Ningxia's boss Zhao Danqiao (Dennis Wu). After learning the truth, Ningxia, who has already had a secret crush on Shudong, decides to bury this feeling silently in her heart. Ningxia finds her cousin Ning Xin (Lv Jiarong), hoping that the latter can meet Shudong on her behalf. At the same time, Zhao Danqiao gradually falls in love with the kind and gentle Ningxia, and the two who love each other finally come together. However, at this juncture, Ning Xin tries to destroy the relationship between him and Ningxia because she covets Zhao Danqiao's rich family background.
