A deafening thunder woke Lin Fan from his sleep. A storm was forming on a summer night. The boy was groping in the dark. The desk lamp was lit. Under the warm yellow light, the boy's pretty face was full of tears. The summer vacation of the third grade of junior high school is a rare holiday for any graduate. Lin Fan had long praised her with friends for spending two crazy months in the Internet cafe in Haikou. However, in recent days, Lin Fan seemed to have a strange disease. He was always drowsy and couldn't sleep enough. He always had the same dream.
