In order to raise money for her younger brother's surgery, Su Ruoqiu, a customer service agent at a social animal company, accepted the outrageous commission of a "three-month contract marriage" with Gu Yanzhi, the rumored "cold-faced king of hell", the president of the Gu family. The two went from being a "acting couple" who disliked each other to revealing their true personalities in "pretending to be in love" - Su Ruoqiu's venomous tongue and tongue-in-cheek attacks on the CEO, while Gu Yanzhi's appearance of being aloof but secretly poking fun at his wife. In dealing with the family's marriage push, workplace oolongs, old acquaintances and other turbulent events, they gradually evolved from a contractual relationship to a two-way sincerity.
