The ten sons of the Lu family in Beijing are all single, which makes the old lady in charge Shen Manjun anxious. Once when she got lost in an old street and was in danger, she was rescued by Su Nianqing, a gentle and tough little flower shop owner, and she fell in love with this "uncut jade" with pure character. According to the birth date calculation, Su Nianqing is the perfect match who can prosper her husband and family, and avert the catastrophe in the fate of her eldest grandson, Lu Tingzhou!
The old lady threatened to go on a hunger strike and even threatened to risk her life on the marriage, forcing Lu Tingzhou and Su Nianqing to get the certificate. This business emperor with a net worth of hundreds of billions, in order to find out his true feelings, concealed his identity and presented himself as an "ordinary employee", and concluded a contract marriage with Su Nianqing, who was eager to escape the difficult situation of being dependent on others.
The two-bedroom cohabitation life is a misplaced collision between a wealthy man and an ordinary girl: he is used to calling the shots, but he has to learn to plan the daily necessities; she is well versed in the fireworks of the market, but does not understand his edge hidden in the ordinary; he clumsily learns to cook home-cooked dishes, and she secretly leaves a lamp to warm porridge for him who comes home late; he secretly clears the obstacles of the flower shop, and she melts his heart that has been frozen for many years with her warmth.
A contract that began with calculation and escape has quietly deteriorated amidst the running-in of getting along day and night and mutual support in times of crisis.
