Sung Suzy (played by Kim Ji-yeon) held a paintball gun and talked to herself about the unpleasantness of transferring to another school.Song Zaixin also reflected on her behavior of secretly filming others and realized that doing so was wrong.They happily confessed their faults and each other's faults, but they didn't feel betrayed at all. Instead, they had a great time.At this time, Kim Da-yeon received instructions from Baek Ha-lin (played by Zhang Da-ah), asking her to seize Pyo Ji-ae as a F.Shim Eun-jung stepped forward to stop Kim Da-yeon, but was unfortunately injured, causing everyone to fall into panic.The school learned that the situation was serious, and the principal was extremely nervous. Bai Xialin's mother immediately came to the school and asked the school to keep the matter secret, which made the situation worse.Kim Da-yeon was anxious about Baek Char-lin's silence, and Goo Seol-ha advised her not to hope that Baek Char-lin would come out to help her face her violent father.Seeing the serious situation, Gao Yinxing (played by Ding Xiatan) suggested that Bai Xialin cancel the game, but Bai Xialin insisted.She actually asked that the game must continue because she was a victim in the game when she was a child, but Myung Ja-en (played by Yoo Da-bin) did not lend a helping hand at the time.She is now obsessed with taking revenge on Ming Zien for her original indifference in the game.Go Eun-sung tried to win over Ye-rin, who was also in the A-level, to punish Kim Da-yeon, but Ye-rin was unwilling to get involved.The head teacher called everyone together in the evening and asked everyone not to talk too much about the matter.Sung Suzy realized that this was just a "cover-up" because Shim Eun-jung was injured, but this was not a fact that the head teacher could cover up.So Sung Suzy countered, believing that a school violence committee should be convened.When Ye Lin learned that Shim Eun Jung might never be able to continue being an athlete, she felt angry at Kim Da Yeon's arrogance and domineering behavior.Sung Suzy understands the fact that someone was covering for Kim Da Yeon's past violent behavior.Baek Charlin suddenly announced that she would punish Kim Da-yeon. Sung Suzy understood that this was Baek Charlin's behavior of not giving up the game even if she died. Even if Kim Da-yeon had to be sacrificed, she must abide by the rules and authority of the Pyramid Game.Ming Zien began to feel that she was the cause of injuries to those around her, which plunged her into pain and fear.Back at school, Sung Suzy began to take action, leaving anonymous messages to everyone asking if they were willing to take action together.Seo Do-ah (played by Shin Seul-gi) is dissatisfied with the adults blocking the news that Shim Eun-jung was injured. She thinks that such a cover-up will only make it more strange. After all, the whole school has already spread the news that Shim Eun-jung was violently injured by Kim Da-yeon.Bai XiaLin's father was intolerable to her personality problems. He didn't even want to deal with the evidence of his corruption that Bai XiaLin had in hand.He insisted that Bai Xialin study abroad, but Bai Xialin understood that for her father, the bomb at home was not evidence of his corruption, but Bai Xialin herself.Therefore, Charlene Bai will never leave this home.Kim Da-yeon was forced to drop out of school, which also meant admitting that she had committed school violence.Sung Suzy discovered that Myung Jaeun began to feel "guilty", so she stopped going to school and even became indifferent to Sung Suzy.After the midterm exam, Gao Yinxing found that she was being taken advantage of by Bai Xialin, because almost all the questions Bai Xialin gave her in advance were not in the exam.Sung Suzy learned from Zhao Shenghe that Ming Zien deliberately kept a distance because of Bai Xialin's threats, so Baek Xialin began to target Sung Suzy, trying to make her a perpetrator of school violence.This made Ming Zien blame herself even more, and she didn't want to let Cheng Xiuzhi suffer because of herself.Now Cheng Xiuzhi decided to give Myung Ja-eun some time to think alone, while she continued to look for more partners to join in destroying Baek Charin's pyramid.She asked everyone why they didn't tell everyone about the problem with this game earlier. In fact, everyone knew that they were also at fault. After all, everyone was a bystander. As long as it was not F-level, everyone felt that they were safe.Sung Suzy believes that the current 13 people can invalidate the game as long as they give up the game on the day of the game.On the day of voting, Sung Suzy prepared everything. Even Zhao Shenghe came to the school, but he did not expect that Yelin would be rushed to the hospital.
