Su Tang, a smart girl who grew up in a loving middle-class family, has a reckless but smart and cute personality. On the day of the interview, she accidentally broke into the president's office wearing casual clothes and bumped into Lu Yanci, the president of Lu Group. This elite CEO, who came from a traditional wealthy family and was groomed to be the heir since childhood, looks cool, calm, self-disciplined and elegant, but his rhythm is unexpectedly disrupted by Su Tang's frankness.
After joining the company, Su Tang was shocked to realize that he was actually the assistant to the president. In the president's office, where elites gathered and the atmosphere was oppressive, she faced various situations: spilling coffee, breaking her skirt, and frequently getting into trouble, but she could always give a brilliant performance at critical moments with her sharp mind. Faced with doubts from colleagues, she struggled to adapt to the rhythm of "involution"; while Lu Yanci seemed to dislike her rashness, but he would calmly help her out and even prepare a dress manual thoughtfully.
In the hilarious interactions, President Bingshan was gradually melted by the enthusiasm of the reckless assistant, and Su Tang also got into Lu Yanci's heart as they got along day and night. How will this unexpected encounter compose a heart-warming love song amidst sweetness and laughter?
