Su Nian is the "perfect template" in everyone's eyes - a partner at a top law firm, a wealthy wife-to-be, and a winner in life. She lives in a golden cage built with flowers and applause, until an anonymous text message reveals the truth: her fiancé is monitoring everything about her with a listening device.
At the same time, a down-and-out former detective named Lu Chen broke into her life. He is ruffian, mysterious, and bottomless, and claims to help her find out the truth.
But when the truth was peeled back layer by layer, Su Nian discovered that what she faced was far more than a control-freak fiancé - it was a conspiracy that had been carefully planned for many years, and she herself was just a domesticated pawn on the chessboard.
The cage door has been opened. Should she continue to be a canary being watched, or should she tear apart this perfect scam with her own hands?
