Due to health reasons, Jiang Yunhe stepped behind the scenes and let her younger brother, Jiang Xingchen, manage the company. A week ago, when her brother suddenly had to go on a business trip, she entered the company as the president's secretary, secretly taking charge of everything. Unexpectedly, Lin Qingqian, a newly hired intern, showed up carrying her brother's dog and claimed she was pregnant with the boss's child and was his wife-to-be. Using the dog as her authority, she threw her weight around the company, imposing rules on the employees. She even went to the boss's home and acted like its mistress. In reality, however, Jiang Xingchen did not even know who she was. After discovering the truth, Jiang Yunhe used her intelligence to expose the accomplices behind the scheme and protect the company. Lin Qingqian received the punishment she deserved, and everything finally returned to normal.
