School 20 15 What is the relationship between Gao En Xing and Zheng Xiuren?

First of all, I learned from my mother that Xiuren and Yinsheng are friends, but why is Yinsheng so afraid of Xiuren?

Moreover, judging from the short message sent by Xiuren, the relationship between Yin Sheng and Xiuren should be good. The theme of this drama is school violence, so we can boldly guess that Xiuren died of school violence, and Eun-sung, as her friend, didn't lend a helping hand, or witnessed some truth but didn't dare to say it, which led Xiuren to become a victim of school violence. So after Xiuren's death, Yin Sheng always had a thorn in his heart and felt sorry for Xiuren.

Xiuren incident is similar to bullying Enfei now, but the result will be different, because with Kong and Enxing, Enfei will eventually get rid of the torture.

Before, they were good friends, but later Zheng Xiuren was bullied by her classmates. Gao Enxing is afraid that if she shows that they are good friends, she will be like Xiuren and then ignore her like everyone else. As a result, Xiuren got sick and no one found out, so she died. And after she died, no classmates remembered her, and then Xiuren's sister (intern teacher) avenged her.
