As a top business trader, the heroine, tired of the intrigues of businessmen, changed her name to an "ordinary personal housekeeper" and lurked in the Lu family, a wealthy family on the verge of bankruptcy. On the surface, she is a meek, respectful and omnipotent perfect housekeeper, but secretly she uses the "tyrant" side of her multiple personalities to shake things up in the capital market, clean up the worms within the group, and engage in high IQ games with insidious and cunning commercial spies (villains). As an unpopular family prodigal, the male protagonist wanted to live a carefree life, but unexpectedly discovered the true identity of his housekeeper. The two went from testing each other to joining forces. In the end, the female protagonist tore off the disguise, completed a desperate counterattack in front of all the big guys in the business world, and rebuilt the business empire.
