Is this the virtue of a lady in the 21st century? She is quick to hit people, throw out a few swear words from time to time, and likes to tease people. Under the "good education" of her parents since she was a child, the heroine Han Leiyan has developed into a person who can fight, swear, and sometimes is very cunning and teases people, but most of the time she hides her true nature. What kind of trouble will such a genuine "lady" cause when she appears in Class 17 of Senior High School?
