Under her best friend's ploys, she almost kills him and is ultimately sentenced to prison, where she dies of depression.

Qin Ran grew up in the countryside. She disappeared for one year and lost a year of high school.

One year later, she was taken to Yuncheng by her biological mother to attend school.

Everyone of status in the capital has received a warning from Cheng family’s Junye: Junye’s wife is from the countryside; she doesn’t understand the circle, doesn’t understand the current circumstances, doesn’t understand the financial markets. Her character is very… in short, please excuse me.
