The 32-year-old concubine Su Wan was once a resolute public relations queen in the workplace. However, because she saw through the nihility of the life of the "Prince King", she took the initiative to work as a salesperson in Party A's company - working from 9 to 5 to fish, maintaining a "fishing but not fishing" attitude toward high-quality men who pursue her. Until the company's newly recruited post-00s intern Gu Yan, who has a naughty face but hides eight hundred thoughts, not only accurately catches her vicious tongue, but also fills in all the loopholes in her "ruining life": helping her make excuses for being late, fending off her ex-boyfriend's entanglement, and even using hip-hop club activities to rekindle her passion for life. When Su Wan found that she was gradually relying on her brother who was six years younger, the hidden crisis was quietly approaching: Ma Baonan's ex-husband wanted to take back the real estate that was given to her during the divorce, her hypocritical best friend plagiarized her plan and got her way, and even the financial elites she once "raised" were secretly tripped up by jealousy... But when she was in the most embarrassing situation, Gu Yan held up her household registration book and said: "Sister is not a queen, but a beacon for me alone."
