In order to repay his father's sky-high medical expenses, Su Nian'an, a top student in the finance department of a top university, reached an agreement with the grandmother of Gu Yanchen, the president of the Gu Group, and moved into Gu Yanchen's cold mansion. In front of others, she is a "harmless little sun" with an overly sweet smile; behind the scenes, she is a "calm complainer" who madly complains about her boss to her best friends. This double-sided personality allows her to maintain her sober self while playing the role of "good sister". Gu Yanchen is a typical giant in words and a dwarf in actions. He uses his poisonous tongue as armor, but unconsciously reveals clumsy tenderness and protection in his actions. In fact, he is a "tsundere hedgehog" who longs for warmth in his heart but shows clumsy care in his actions. In the "pseudo-orthopedic" life of the two people under the same roof, they went from mutual dislike to ambiguous attraction. Su Nian'an is not a silly girl waiting to be rescued, but a master of "pretending to be a pig and eating a tiger" with high IQ and EQ, and full of hidden skills. She constantly fights back with her own strength in the workplace, making her the ultimate "slap in the face" villain. As the relationship between the two upgraded from an employment relationship to a secret comrade-in-arms, their ambiguous feelings gradually heated up as they fought side by side. However, an elaborate frame-up caused by jealousy made Gu Yanchen choose to be suspicious, causing the relationship between the two to break. Can Su Nian'an, who left the Gu family, reunite with Gu Yanchen and turn a show that started with money into a two-way journey that ends in love?
