Yang Chengxi is a freshman. When she first started school, she met An Zehong, a sophomore who was the president of the student union. An Zehong developed feelings for Yang Chengxi. Yang Chengxi, who was unaware of this, mistook her admiration for Qiao Zhexuan, a classmate from the same club, for liking her. An Zehong's ex-girlfriend is named Ling Xuemeng. They had a relationship for three years, from the first year to the third year of high school. When it was time to take the college entrance examination, Ling Xuemeng insisted on studying abroad. Between going abroad and An Zehong, Ling Xuemeng chose the former. After the two broke up, Ling Xuemeng thought An Zehong was just acting like a child and ignored him. What she didn't expect was that An Zehong was serious. Ling Xuemeng, who was an exchange student in her junior year, came to Fengfan University as an exchange student. But she found that everything was not what she thought, everything had changed. She was mentally unbalanced and blamed all the faults on Yang Chengxi. She pretended to be very magnanimous and was very nice to Yang Chengxi. She wanted to use her to get An Zehong. If she didn't get it, she would destroy Yang Chengxi. What she didn't expect was that Yang Chengxi was very kind to her even without Yang Chengxi.
