Reborn: I Keep Having to Rein In My Brother's Urge to Fight

In Lin Ran's previous life, her family's tragedy began when her older brother, Lin Muhan, got into a fight with local thugs during his senior year of high school. His leg was left permanently crippled, and after that, the Lin family's business went into a steep decline for one reason after another. Her parents died one after the other, and Lin Muhan became listless and despondent. Lin Ran had no choice but to shoulder the burden of supporting the family, taking on all kinds of odd jobs to make money... One day, she returns to the age of fifteen, before the tragedy has taken place. She resolves to keep an eye on her brother at all times and stop him from getting into fights, so he won't get hurt. She also plans to use her memories of her previous life to help her father prepare in advance and change the Lin family's tragic fate. Lately, Lin Muhan has found things a little strange. Every time he's about to get into a fight, his little sister appears. She's practically haunting him. He suspects there's a mole in his circle working for her... From then on, Lin Ran is either studying or on her way to stop her brother from fighting. At first, Lin Ran is devoted to her studies, with nothing in her eyes but school and family. She never expected to meet someone who would care for her so deeply...
