Chen Qili is my college classmate. He has severe obsessive-compulsive disorder. We have the same living environment but different lifestyles. He is lonely and proud, and is ridiculed by others for being nicknamed "Triangle Monkey" all day long. He fantasizes every moment about a passage that belongs to him and allows him to run endlessly. He also had his own love, but when faced with the world, he seemed fragile. How difficult and difficult his life and love were over the years, how gorgeous and vigorous, and how it made people laugh.
