When her brother gets into trouble and injures another girl, Ying Xian meets with the girl's older brother Fu Cheng (Hao Fu Shen) to discuss the situation. While Fu Cheng, being from a humble background, is put off by Ying Xian's way of handling things, he accepts her job offer as her bodyguard in order to earn money to pay for his sister's medical bills.
