Yu Xingchui, a social animal who inherited a house worth tens of millions of dollars, accidentally became a neighbor of his boss Liu Yu'an, and began a workplace and neighborhood life of fighting wits and courage with Liu Yu'an. In the process, the two happy enemies secretly fell in love. At this time, Liu Yu'an's mother Yang Xu, who had disappeared for many years, came to the door, and she was the one who arranged for Yu Xingchui to live in this house behind the scenes. Yang Xu told Yu Xingchui that her father jumped from the high-rise building that Liu Yu'an was in charge of, but it left a huge shadow on Liu Yu'an. Yu Xingchui, who learned the truth, understood Yang Xu's good intentions, helped Liu Yu'an get out of the haze, and finally the two came together.
