In the glamorous Los Angeles City, the top wealthy families Gu and Lin maintain a seemingly harmonious marriage covenant. A sudden change puts the "fake daughter" Lin Wei (formerly known as Su Xiaoya), who was carefully cultivated by the Lin family and used as a marriage pawn, into a desperate situation - her true identity is actually an orphan who was taken in by mistake in the hospital back then. Su Man, who is a real bloodline of the Lin family and lives in the market, is struggling in the quagmire of life.
In order to save the Lin family, which was on the verge of bankruptcy, and to protect the humble longing for "family" in her heart, Lin Wei was forced to accept the absurd deal proposed by the Lin family: as "Lin Wei", she would marry Gu Chengze, the cold-blooded and iron-blooded heir of the Gu Group, instead of Su Man, the real daughter who hates wealthy marriages.
On their wedding night, facing Gu Chengze's insightful yet playful gaze, Lin Wei knew that what she had stepped into was not a magnificent palace, but a cage filled with thorns and lies. Under the cold terms of the contract marriage, there are Gu Chengze's unfathomable temptations and vaguely burning attention. She works step by step, trying hard to play the role of "Lin Wei", struggling to deal with the complicated power struggle of the Gu family and the greedy demands of the Lin family.
At the same time, the real daughter Su Man, who suddenly learned of her life experience, returned to the upper class of Luo City under the "arrangement" of the Lin family, full of unwillingness, resentment and hostility towards the "dove occupying the magpie's nest". Her goal is clear: to regain everything that belongs to her - identity, wealth, status, and the dazzling man Gu Chengze who should have belonged to her. Two girls whose destinies were mismatched faced each other head-on at the center of the whirlpool of a wealthy family.
