Han Xingmian, an energetic girl from a martial arts family, is naturally low-frequency hearing-impaired! When taking on a mission, she mistakes Zhou Ci, the blind and reclusive president of the Zhou family, for 'Little Cat Zhou', kicks open the iron door, and directly carries him away in a princess carry. She happily lands a monthly salary of 200,000 to take the job of coaxing the president to become cheerful. The low-bass president happens to hit her hearing blind spot, leading to hilarious miscommunication throughout. With her martial arts skills protecting her master, she fiercely rebukes harsh relatives and even barbecues the president's prized ornamental fish into grilled fish. While his stepbrother secretly seizes power and closes in step by step, amidst the goofy daily life there is a mutual healing, and the two hide a fateful bond from their youth encounter.
