The female protagonist, Xiao Xi, has three elder brothers who all receive a phone call saying that their sister has been found and is getting married at the Imperial Court Hotel today. They all want to be the first to see their sister. The eldest brother has invested tens of billions of funds into the company of Xiao Xi's fiancé, Su Yifan. Xiao Xi's adoptive father comes to the hotel to attend the wedding but is harassed by the security guard at the entrance and is not allowed to enter. Fortunately, Xiao Xi comes to pick up her adoptive father and takes him into the hotel.

The four siblings promise to take good care of their adoptive father in the future. Xiao Xi returns home and is spoiled by her three overprotective brothers. At the exhibition and project bidding meeting, the despicable second male and female leads appear again to seek attention, only to be humiliated by Xiao Xi and her brothers.
