Is Gao Enxing in the TV series "who you-School 20 15" dead?

According to my repeated inspection, since the school episode 20 15 1, when Gao Enxing went to the toilet, a person's shadow and shoes appeared. Just as everyone was about to take a group photo together, Li Shizhen rushed over and looked at the toilet with a bad face. Later, when taking photos, she saw that her shoes were the shoes that were taken into the toilet to turn off the lights. Therefore, she is probably the murderer. Li Shizhen is probably jealous of their friendship, hatred, so would make such a move.

Another possibility is Zheng Xiuren. In the play, the name Zheng Xiuren has been mentioned all the time, but no one knows what the truth of Zheng Xiuren's death is. There are always mysterious people who send messages to Gao En to mention Zheng Xiuren. Zheng Xiuren's death must have something to do with Gao Enxing. According to Gao Enxing's mother's sudden face change when she saw Zheng Xiuren's mother, it can be seen that the person who has been bullying Gao Enxing is probably related to Zheng Xiuren.

The last one that everyone inferred may be Min Zhun, the class monitor. Monitor Min Zhun's father is the policeman in charge of the school. Monitor has always been the second in the class because of Gao Enxing's existence, and his mother attaches great importance to his achievements. In order not to disappoint his mother and satisfy his vanity, he has been stalking and threatening Gao Enxing. Therefore, the monitor is probably a pervert.
