Episode 5

Sung Soo-ji (played by Kim Ji-yeon) is distraught, and she knows that some changes must be made.She thought that if she could convince Yelin to become F, she might be able to attack the power of the pyramid, reveal everyone's true attitude towards Yelin, and see if they would really bully her.However, Yelin was unwilling to put all her bets on Sung Suzy, so she declined the proposal.At this time, people in the group discovered that Zhou Chengyi (played by Yin Kerer) decided to commit suicide because she was F.Sung Suzy immediately realized that this was Baek Charin (played by Zhang Duya) and used Zhou Chengyi to frame herself.Bai Xialin even hinted that Cheng Suzy said that all this was her mistake, suggesting that Cheng Suzy found an excuse for Zhou Chengyi and threatened her, making her choose to commit suicide.All of this was Bai Xialin's psychological manipulation, which made Cheng Xiuzhi feel that she was completely insane.On the other side, Teacher Yoon told Sung Suzy’s father that Sung Suzy was a victim of campus violence in Happy Class.The parents were shocked when they heard this, but what happened at the scene was that everyone was blaming Sung Suzy for threatening Zhou Chengyi, and Sung Suzy's father also saw this scene.This made Sung Suzy realize that Baek Charin's "it's not over yet" meant that she was going to frame her.Baek Charin took advantage of this opportunity to seize Sung Suzy's weakness, and even acted like a peacemaker in front of everyone, improving her status in everyone's mind.Sung Suzy must accept punishment. Da Yeon proposed to confiscate Sung Suzy’s voting rights in the 15th Pyramid Game. This was almost a fatal blow to the D-level alliance.Sung Suzy felt that she had to take action and began to ask Zhou Chengyi what she was threatened with.She said that she did not remember bullying Zhou Chengyi at all, and she would not admit it unless there was evidence.Sung Suzy even directly confronted Da Yeon, saying that if she thought she almost killed Zhou Chengyi, what about those classmates who wanted to commit suicide because of Da Yeon's bullying? Baek Charin suggested voting and using the game's ecology to control everyone's decisions.Because no one dared not follow her suggestion.Outside the classroom, Seo Do-a's (Shin Seul-gi) father expressed his approval of children's non-violent ways of solving problems, but Teacher Yin thought this was simply a public execution.Teacher Yin originally wanted to go in and save Cheng Xiuzhi, but was threatened by Baek Charin's mother.After the voting ended, Sung Suzy confirmed that she had lost the right to vote next time, but Yerin mentioned that she could still get votes this way.Cheng Xiuzhi knew that she was doomed, but she felt that Bai Xialin seemed to have a trick up her sleeve.She felt that everything was not over yet, and she couldn't help but wonder how Bai Charlene knew her next move and who to approach.At the same time, Teacher Yin was reprimanded by the principal for being disorderly, but she believed that someone in the school was acquiescing to this kind of campus violence.Sung Suzy realized that she had to bring in more people and could no longer use threats.She decided to use her sincerity to persuade others, just like Ming Zien (played by Yoo Da Bin), who used her sincerity to persuade Ji Ai not to betray her.Baek Charin has decided to make Myung Ja-eun F, but Sung Suzy seems to have found a way to destroy the pyramid, which is to slowly disintegrate Baek Charin's image through the important role of Yelin.Yelin immediately told the class that Bai Xialin violated the rules of the game by letting parents know about the existence of Pyramid Game during the observation day.Although no one dared to say anything wrong with Bai Xialin verbally, after voting anonymously, everyone dared to express their thoughts on Bai Xialin's violation.Next is the plan to get rid of F, but before that, Yelin must become A-level.Through the voting of the D-class alliance, Yelin can indeed squeeze out Baek Charin, and it can also use Yelin's popularity and image to make the whole class fight against Baek Charin.However, it was suddenly revealed that Yelin's debut was made possible by her parents' connections and money.Bai Xialin said that the photo in the report looked like it was taken in a classroom. In fact, the angle of the photo came from Zhou Chengyi.Teacher Yin entered the classroom and said that she set up the camera. In order to understand this strange class, Teacher Yin finally resigned angrily, but she hoped that Cheng Xiuzhi would not lose.Sung Suzy now understands that Myung Ja-eun betrayed everyone, so she asks Pyo Ji-ae to leave the D-class alliance.Ming Zien comforted Cheng Xiuzhi and said that at least she had changed herself, and she also understood that Zhi Ai and Zhou Chengyi were friends, so she spoke softly.Myung Ja-eun knew that Sung Suzy wanted to become F and the evidence would be captured by the camera, but now that there is no camera, Sung Suzy decided to implement plan C to at least prevent Myung Ja-eun from becoming F.After voting, the classes really began to be shuffled, Ye Lin became A, Myung Ja Eun and Sung Suzy were both D, Da Yeon became B, and Go Eun Sung (played by Jung Ha Dam) was promoted to A level, and Yoon Rui Won and Shim Eun Jung both became Dclass.
