When the Cheng family fell into decline, the daughter Cheng Jinxin was forced to sign a hidden marriage agreement to save her seriously ill grandfather, and married Lu Shiyan, a business emperor who was rumored to be ruthless and powerful. The outside world thinks that she is a dodder who clings to the rich and powerful, but little does anyone know that late at night, this cold-faced Mr. Lu will warm a glass of milk for her and calmly clear the way when she is in trouble. During the days of the secret marriage, while Cheng Jinxin worked as a low-level designer in Lu Shiyan's company, resisting the exclusion of colleagues and the frame-up of her love rival, while getting along with Lu Shiyan, she gradually glimpsed the tenderness and past pain behind his cold mask. When the truth of the family's old case came to light, and when the secret of the hidden marriage was exposed, Lu Shiyan protected her behind him and declared domineeringly: "When will my wife need to be hidden?" The marriage that began with a contract eventually settled into the most sincere love through thick and thin.
