At Ying De University, Li Zhen befriended Dong Shan Cai, who was also middle class student. Li Zhen angered the F4's leader Dao Ming Si, after she tripped and accidentally throwing some trash on him. Her apologies were rejected. Her friend, Shan Cai stepped in and defended Li Zhen, transferring the anger to herself. Li Zhen started to avoid Shan Cai, when she received a red notice from the F4.
Once the other students started bullying Shan Cai less, Li Zhen was able to speak to her in public again. She was invited to Teng Tang Jing's birthday party, but had nothing to wear. Shan Cai gave her a dress that Si had given her. At the party, Si was annoyed at Li Zhen wearing it and insulted her. She promptly left the party, after the encounter.
Li Zhen went out dancing with classmates, Shan Cai, Bai He, Qian Hui, and Chen Qing He. By the end of the night, Li Zhen appeared to be intoxicated and Shan Cai askes Qing He to take her home. She later revealed that she pretended to be drunk at the time. After Qing He dropped her off, she went back and followed Shan Cai. She took pictures of Shan Cai and Thomas going into a motel and spread them around school. Si felt betrayed by Shan Cai and got drunk. He mistook Li Zhen for Shan Cai and kissed her. Li Zhen then brought him to hotel and revealed her feelings for him. He rejected her and told her never to mention the incident again.
Si obtained the address of the person who took the photos, which lead to Li Zhen. Shan Cai refused to believe that it was Li Zhen. However, Li Zhen confessed to the whole thing and expressed jealousy toward Shan Cai. Shan Cai apologized for being the source of Li Zhen's hate and gave back a toy bear Li Zhen had gifted her. The next day, Li Zhen dropped out of Ying De and transferred to a different school. Li Zhen placed the bear with a new message in Shan Cai's locker, before leaving.
She had long, black hair, similar to Shan Cai's. Li Zhen had an oval-shaped face and dark brown eyes. At school, Li Zhen wore comfortable, everyday clothing to school.
Personality and traits

Along with Shan Cai, Li Zhen was one of Ying De's few lower-class students and was ignored by the school's rich students. Li Zhen appeared to be loyal to Shan Cai, despite sometimes avoiding her after Shan Cai received a red card. However, Li Zhen later revealed that she had been jealous of Shan Cai's likability as well as Si's affection for her.
