An unexpected cocktail party forced the lives of business elite Chen Bing and designer Su Wan to intertwine - Su Wan became pregnant. Faced with the pressure from his family to get married and the responsibility for his children, Chen Bing proposed to sign a "contract marriage" and promised to provide Su Wan with material security, but drew a clear line between "not talking about feelings".
Married life begins with alienation: he is the resolute Mr. Chen, and she is the cautious Mrs. Chen. The two of them maintain a superficial peace like roommates. But getting along day and night during pregnancy gradually loosened the cold contract: he would silently note down her taboos and give her warm water when she had morning sickness; he would stand up for her when she was being challenged and publicly declare her identity; he would quietly leave a cup of hot milk when she stayed up late to change the design.
When "responsibility" slowly turns into "concern", when "alienation" turns into "dependence", Jiang Ruotong's provocation, the media turmoil, and the exposure of the contract become the touchstone of their relationship. Chen Bing finally understood that he cared about Su Wan beyond the contract; Su Wan also saw clearly that this man, who was cold on the outside and warm on the inside, had already lived in her heart.
From "unexpected pregnancy" to "contract marriage", from "respecting each other like ice" to "deep love forever", Chen Bing and Su Wan used time to prove that some marriages may start by chance, but true love will eventually arrive as scheduled with each other's protection.
