The Su family, one of the wealthiest families in the country, is on the brink of collapse. Their only lifeline is a marriage alliance with the even more powerful Shen family. Shen Yuheng, the cold and ruthless head of the Shen family, has named his bride: Su Wanyi, the Su family's only daughter, who already has a beloved boyfriend, Gu Ze.
Shen Yuheng, head of the Shen Group, claims he is offering financial support, but insists on marrying Su Wanyi. In truth, he is hiding a dark secret buried for ten years, involving a fire, lost memories, and a stolen identity.
As the marriage goes on, Su Wanyi gradually realizes she is like a canary trapped in a gilded cage. Shen Yuheng has been watching her closely, even manipulating her life, for years. She fights back at every turn, trying to uncover the truth behind strange code names like "Returning Bird" and "Project Mockingbird," only to discover that her entire life has been a carefully rewritten lie.
