Chen Yu was once cheerful, sunny, and full of energy. As a branch deputy general manager at a securities investment firm, he had a bright future ahead of him. But losing his job ten years ago sent his life into a steep decline. After that, he could only take scattered night shifts. Unable to accept his failure, he gradually sank into delusions. One day, convinced that someone was trying to steal his ideas, Chen Yu smashed his phone in a fit of rage. Then, like a cornered beast, he frantically searched his room, certain that a tiny black spot on the wall was a surveillance camera, and attacked it with a chair. When a neighbor came to ask what was going on, Chen Yu assumed they were part of the conspiracy. The helpless neighbor called the police. When the officers arrived, Chen Yu saw them as enemies too and fought back violently before they finally subdued him and took him to the police station. There, Chen Yu rambled incoherently, insisting he had been framed and had a grand plan to save the world. The police contacted his friend Xiao Li and notified the hospital. Doctors diagnosed Chen Yu with severe delusional disorder and said he needed inpatient treatment, revealing the tragic life of a man who had been driven to escape reality and sink deeper into delusion by the blow of losing his job.
