Lin Shuyue has three goals in life: to eat well, to wear warm clothes, and to save money for her brother's medical treatment. For this reason, during the day she worked as a scorned handyman in a foreign trade company, and at night she worked as a poor girl in the alley who helped people sew and wash. Until that day, for the "huge sum" of three gold bars, she took on a job - pretending to be the "Seventh Miss" of the Bai family, a wealthy family in Shanghai, to attend a three-day cruise ship banquet. The start is hell. The real ladies talked about Paris Haute Couture and Van Cleef & Arpels, but Lin Shuyue only knew about fabric shrinkage and which rice shop was the cheapest. The noble gentlemen were talking about cigars, horse racing, and current politics. Lin Shuyue just wanted to ask if the buffet on the ship could be packed. Seeing that she was about to die on the spot, she thought out of her wits and set up a personality for herself: a simple little white flower who had just been found from the countryside, was ignorant of the world, but was deeply loved. The people were established, but trouble also came. Lu Shiqian, the legendary young marshal who was decisive in killing and feared by everyone, took a keen interest in her, a "country bumpkin". He always appeared on the verge of Lin Shuyue's secrets being exposed, staring at her with his eyes that could see everything, half-smiling but not smiling: "Miss Bai Qi, do you know how to make an abacus?" Lin Shuyue (leaning back in horror. Jpg): I, I was helping my sixth sister count how many pieces of jewelry she has! Lu Shiqian (meaningful): Oh? Why don't you help me calculate how many guns I have in my arsenal? Lin Shuyue:... Help! The risks of this job are beyond the limit! QAQ thought that they would be able to take the money and run away in three days, hiding their merit and fame. Who would have thought that the real daughter of the Bai family would never return?
