This is a story about Yunxi and Xiaoyezi. In Bianhuahua, I believe there is love between them. That's why Yunxi let go. Xiao Yezi chose to die for his brother and also so that Yunxi could come out. It's just that the hatred is so strong that even Xiao Yezi himself won't admit it. I like the ending in the book. Both of them have no desire to live, and death is the best destination. This story is to let them understand their own hearts and go to hell together.
