Pure college student Zhong Yu wakes up to find a five-year-old daughter mysteriously dropped from the sky, and the child's mother turns out to be Qiao Qingwu, the cold and abstinence-driven female president of his company! Facing this cute baby who time-traveled back from eight years in the future, the two are forced to start a cohabiting child-rearing life of 'pretending to be unfamiliar in public and sleeping together in private'. From initially looking at each other with mutual disdain to gradually falling in love with the daughter's divine assists, the aloof female president transforms into a clingy little wife, while Zhong Yu becomes a fierce protector of his wife. Amidst the chaotic yet lively daily routine, the family of three pre-reads a future of sweet and happy married life. Turns out, they were destined for each other all along.
