Five Chairs in the Classroom

Li Qianqian, D in mathematics, failed four subjects, ranking 36/43. 170,140 Pounds. Introverted and doesn't like to talk. Ask her and everything is "okay". I get up after being called three times at 6:20 every day. School ends at 17:50 and lights out at 22:00. I wake up at 6:00 on weekends, curl up in bed and watch my iPad. She likes Kudo Shinichi. "I don't like to escape. I like to face it." She likes to read mystery novels. "Forensic doctors are not gods, they just look a little more carefully than others." But she spent all her "carefulness" on reading comics and novels. Homework depends on searching for answers. Exams depend on luck. Mom asked "how was your day" – "okay". Dad asked, "Is there anything you want to tell me?" - "No." Then she had a dream. The year in the dream is 2046. She has no education. No skills. There is no social security. Squatting on the roadside waiting for the day's work. And sitting in the Xinchuangyuan office building was her crush - he didn't see her through the glass. She woke up. 3:14 Am. The D on the paper is still there. She fell asleep again - but the dream did not let her go. My younger sister, Li Qianqian, turned off the lights every night and said to her through the 1.5-Meter darkness: "Sister, can you solve the problem as if you were solving a crime? The condition is the evidence, and the answer is the murderer." My mother wrote a letter but did not send it: "We won't guess what you are thinking. If you close the door, we can't get in. If you open a crack, we will know that you are there." That night, she pushed the door open a crack. This is 2026. She still had time.
