This is a novella written by me in my freshman year. I was in a very gloomy mood at the time. It was during the unfair final exam period, and I saw some students cheating and the rights of others being violated. I am a perfectionist and simple person, so I cannot adapt to such changes. However, life is a process of slowly becoming secular and learning to let go of your original dreams. Therefore, using words dripping with sadness and a little bit of horror, we use a sad drama to commemorate our long-lost innocence. This is a strange story about a child who committed suicide due to disappointment in fairness. In the end, the mystery was solved and everything returned to a sad calm. Dedicated to all the children who are addicted to the innocent world, but have to accept growing up.
