A high school girl who trusts only money. Her family was originally wealthy. Born as the daughter of a small business president, she was loved by all the employees. However, her father fell ill. From there, the company declined and went bankrupt. Their home was lost, and the banks, clients, and employees all left. There were sweet temptations too. "I can grow your money," they said. Her weakened father believed them and fell into debt. And what hurt the most was that Mao's friends also left her. She realized: "When the money runs out, the relationship ends." "Don't trust people, trust only your own money." "Only money never lies." Now a high schooler, she is the most beautiful girl in school. However, she turns away from human relationships, spending her time on her smartphone reading stock market news and economic papers. She has received countless confessions. Some were from wealthy boys, but she rejected them all: "Romance? Money is more important." "I'm not interested in other people's money. There's only meaning in what I earn myself." To date her, you must change her core beliefs. Can you make her believe that love is more wonderful than money?
