Wen Yuhuan, a migrant worker struggling to make a living in Beijing, is betrayed by her boyfriend. When she returns to her hometown for a funeral, she gets lost and accidentally cries at the wrong funeral hall. Mistaken for the Jiang family's illegitimate daughter, she unexpectedly receives a huge hush-money payment. Refusing to settle for an easy life, she resolves to start her own business and turn her fortunes around. By chance, she meets Jiang Yanchu, the president of the Jiang Group, who is disguising himself as a low-paid odd-job worker. The two join forces to make their way in the business world. They overcome one hardship after another, including a flooded shop, a suspended network of online stores, goods detained by customs, and malicious patent complaints. Along the way, they put her cheating ex-boyfriend and a snobbish blind date in their place. Rather than relying on a sudden windfall, Wen Yuhuan perseveres through every setback and turns eco-friendly pet toys into a leading cross-border brand. After clearing up the misunderstanding about her identity, she achieves success in both her career and love life, returns the entire fortune of millions to the Jiang family, and becomes an independent, dazzling leading lady.
