After being squeezed dry by a heartless company, 25-year-old Lu Chen, a finance master's graduate from a top-tier university, suddenly sees the light: instead of being a corporate wage slave, why not go back to a wealthy family and take it easy?
At his parents' suggestion, he becomes a servant at the Gu family villa. His meals and lodging are covered, and there's no overtime. His daily routine consists of watering flowers and washing vegetables.
But the Gu family's four daughters are all forces to be reckoned with.
The eldest, an icy female CEO, treats his master's thesis as a business case study.
The second sister, who had a crush on him for three years in middle school, reunites with him and confesses using a painting she made in high school.
The sharp-tongued lawyer third sister casually digs into his entire background.
And the pretty, lively high schooler fourth sister treats him as her most interesting new toy.
Lu Chen had planned to lie flat, but soon discovers that undercurrents are swirling through the Gu family's mansion.
When the Gu family faces a crisis, he stops staying silent. Drawing on his knowledge and broad perspective, he rises from servant to the power behind the throne, and gradually realizes that his bond with the four young ladies has long gone beyond that of master and servant.
