Factory worker Lin Xiaoman has flour fish-making skills that surpass the entire factory. After getting drunk at a celebration banquet and entering the wrong room, she wakes up and mistakes group chairman Lu Ming for a male escort, dashingly leaving behind 800 yuan before walking away, completely unaware that the two had secretly obtained their marriage certificate that very drunken night. By a twist of fate, she moves into the Lu family villa, believing she is just working as a fake girlfriend to earn money, only to accidentally uncover the marriage certificate and reveal a heaven-shaking secret. Scheming socialite Zhao Manlin closes in step by step, factory villains set up successive stumbling blocks, and former colleagues frame her. After becoming pregnant, Lin Xiaoman is repeatedly plotted against, experiencing misunderstanding, betrayal, and departure. Relying on her craft, Lin Xiaoman makes a comeback against the wind, tears apart conspiracies, and secures intangible cultural heritage recognition for flour fish.
