Three years ago, Su Nian was an unwanted and abandoned daughter of the Su family, who was given to the critically ill business tycoon Lu Yanzhou as a "lucky gift". The wedding was as deserted as a funeral, the groom was unconscious throughout, and everyone was waiting to see her kicked out. Three years later, she returned quietly with her genius son Xing Xing. Unexpectedly, the cute baby pointed at the cover of a financial magazine and exclaimed: "Mommy, this uncle looks like my father before he lost his memory!" At that time, the Lu Group was on the verge of bankruptcy, and all the ladies in the city were waiting to see Su Nian's joke. Unexpectedly, Xingxing held the tablet computer and invested a sum of money to buy 51% of Lu's shares. He announced in a sweet voice: "Uncle, you will be a bodyguard for me and mommy from now on!" After Lu Yanzhou woke up, he lost part of his memory and had no memory of having a wife and children. But facing this little boy whose features and eyes looked exactly like his own, and who was incredibly smart, the dusty softness in his heart was severely hit. On one side is Su Nian's cold and distant "the past has been changed", on the other side is the star-studded "Daddy, chase mommy". The former cold CEO had to put down his body and clumsily learn to cook, pick up and drop off from kindergarten, play with Lego, and start a long road to chase his wife. And Su Nian, looking at the man who once didn't even look at her, was willing to lie on the carpet to find Lego parts for his son, the defense in her heart began to collapse inch by inch. Sweet and cute baby, the two powers join forces; the cute baby assists, and the CEO is busy chasing his wife. It turns out that all the shortcomings of fate are for this moment of perfect reunion.
