The heroine Wen Yuyuan, who has always been independent, refused to go abroad and persuaded her parents to stay in China after learning that her parents were about to take her, a sophomore in high school, and her younger sister who had just turned one year old to settle abroad. The reason is that she is used to life in China, but actually she doesn't want to be controlled by her parents anymore. She sees herself as mature and wants to live the independent life she has always longed for. However, not long after her parents left, the family received an uninvited guest: her cousin, Ling Yun, who was 5 years older than her. Wen Yuyuan was not familiar with this cousin because he did not live in the same city and only saw him once or twice a year. He only heard that he was very good. He came to live at her house because, on the one hand, he happened to be in his first year of graduate school in City C, and on the other hand, his parents were always worried about a high school girl living alone. However, what they didn't know was that Ling Yuan's arrival disrupted all Wen Yuyuan's ideas...
Purpose: It mainly tells the story of a rebellious adolescent girl who gradually grows up under the doting and strict discipline and care of her handsome academic brother, and finally gets admitted to her ideal university.
