Su Wantang, the daughter of a wealthy merchant in the south of the Yangtze River, was sent to the palace as an Omega by her father as a concubine. In the Alpha-dominated Zhou Dynasty palace, she relied on her calm and witty character and keen pheromone perception to deal with the difficulties and frame-ups of the Alpha concubines in each palace, and was promoted step by step from a concubine to a noble concubine. In the process, she had an emotional entanglement with the suspicious and powerful Alpha Emperor Xiao Jingheng, using his power to consolidate her position while maintaining her independence; at the same time, she exposed various conspiracies against her in the palace (such as concubines framing her, family exploitation, and foreshadowing of old cases), and finally became the master of the harem, realizing the cool point of "controlling her destiny without relying on Alpha."
