Guan Mengmeng, a Chinese girl with e-commerce dreams, traveled to the Kingdom of Mambo only to have her ambitions shattered by a boyfriend's betrayal. A twist of fate led her into a "contract marriage" with Crown Prince Song Pai, who was grappling with a succession crisis. Seizing this opportunity, Guan Mengmeng restarted her career in the royal court with modern e-commerce thinking, unaware that Song Pai had already begun to secretly admire her. As they joined hands to promote goods from both countries, the pair fought against the traditional forces led by the second prince and uncovered numerous conspiracies. Bound by a century-old karmic fate linked to a snake-shaped pendant, their fake relationship blossomed into genuine love while they fought side by side. In the end, they achieved success in both business and true love.
