A cold contract marriage forcibly intertwined two completely different worlds. Ling Mohan, the ruthless leader of the Ling Group, bears the responsibility of the family and childhood trauma, and believes in profit first. In order to solve the inheritance crisis, he needs an absolutely controllable "wife". Su Wanqing, a beautiful and tough ordinary girl, resolutely signed a marriage contract to protect her seriously ill relative and became his nominal wife. Living under the same roof, she abided by her duties and tried hard to maintain distance, but as they got along day and night, she quietly penetrated his frozen heart with her inadvertent tenderness and tenacity. He was used to controlling everything, but for the first time he lost control because of her, and a strong desire for possession and protection arose spontaneously. However, the difference in identity, the uneasiness and suspicion in the past, and Ling Mohan's inherent domineering and poor expression have made this relationship difficult to move forward amidst misunderstandings and struggles. When the contract expired and the truth emerged, the scarred Su Wanqing decided to leave, reinvent herself, and shine. At that time, Ling Mohan, who was condescending, had already fallen deeply in love and couldn't extricate himself. Suddenly he woke up and embarked on a journey of chasing his wife that was inevitable and step-by-step. At the same time, the gentle and protective doctor Gu Chenfeng gives Su Wanqing rare warmth, the paranoid and crazy daughter Bai Weiwei sets up many obstacles, and the secret trauma of the past is gradually revealed... This is a love game that begins with a transaction. Watch how the cold-hearted CEO surrenders to love and learns respect and true love; how the contracted wife emerges from her cocoon and becomes a butterfly, winning dignity and independence. In the end, can they overcome many obstacles, heal each other's scars, and compose an urban love song about love and redemption together?
