Construction worker Zhang Zhexiu (Wu Zhihao) is a kind-hearted man, but in order to support the three nephews left behind by his deceased older brother and sister-in-law, he has to appear tough, rough, and stingy, taking on all kinds of jobs related or unrelated to construction to earn more money. Zhao Anna (Han Yise), who lost her parents at a young age but inherited a fortune, is very proud and arrogant, and there are basically no things in the world that can catch her eye; even her husband Park Bili (Jin Shengmin) is treated like a servant by her. Zhang Zhexiu encounters Zhao Anna three times and loses money each time, vowing to find a chance to get it back. After Park Bili declares that he can no longer tolerate Zhao Anna, she sits alone drinking on a luxury yacht during a rainy night and accidentally falls into the sea. As her body cannot be found, Park Bili assumes Zhao Anna is dead and cannot hide his excitement, but Zhao Anna is rescued and taken to a hospital, albeit with amnesia. In the hospital, Zhang Zhexiu discovers the amnesiac Zhao Anna, and just as he is about to hire a nanny to take care of his three nephews, he gets an idea and tricks Zhao Anna into thinking they are in a romantic relationship, calling her 'Luo Sangshi' and bringing her back home.
