After I Scored Zero in the College Entrance Examination, My Stepsister Collapsed

In the Jiangcheng College Entrance Examination, I scored zero, while my stepsister ranked among the top students! My parents called me useless, and she pretended to comfort me, but she didn't know that I had seen her hiding the corner of my answer sheet. Stealing my notes, cutting off my pen refills, and replacing my answer sheets, do you really think I'm a weakling? U disk video and school gate surveillance, I have double ironclad evidence! If you dare to ruin my future, I will ruin your reputation beyond repair!
