First, the story of mathematician Descartes runs through the whole play. As we all know, this story of Descartes actually runs through the whole play. Even in the last episode, Zhang Dongsheng told Zhu Chaoyang before he died? You can believe in fairy tales. Before the sentence was finished, Zhang Dongsheng was killed. It can be said that Zhang Dongsheng has been killed by the police on purpose, so Zhu Chaoyang, the only survivor, can make up these lies at will, so this story has a fairy tale side and of course a betrayal side.
Secondly, Descartes' story implies Zhu Chaoyang's betrayal in the play. On the betrayal side, Zhu Chaoyang betrayed Pupu and Yan Liang, and he always wanted to uproot them. When the two of them were not eradicated one day, Zhu Chaoyang was very worried. He was worried that his life would be disrupted and his employees would collapse, so Zhu Chaoyang was really dark. Descartes' story just proves this side of betrayal.
Thirdly, the story of Descartes mathematician is to tell you that there are two sides to this ending, and which side you believe is which side. Descartes, a mathematician, is repeatedly mentioned in this play to let everyone know that the ending of this story has two sides. Which one do you want to believe is the ending? If you are willing to believe in fairy tales, the ending must be happy. If you are willing to believe in betrayal, the whole play will be gloomy.
To sum up, I can find that the online drama Hidden Corner always mentions the mathematician Descartes, but it implies that the ending is actually two-sided. What do you think about this? You can talk about it in the comments section and discuss it together.
