Reincarnated as the Villain's Sister

In her previous life, Lu Qingyan was a quiet, obedient high school girl known for her good grades and fragile health. But the one person she loved the most was her older brother—gentle, brilliant, and burdened by the world. No one noticed his silent suffering… until it was too late. The day he took his own life, she shattered. Months later, while saving a child from an oncoming car, Lu Qingyan dies and awakens inside a familiar story: the school novel "A Thorn in the Crown", one she read during her lowest days. Only now, she’s not herself—she’s Lu Qingyan, the hot-headed, notorious younger sister of the story’s villain, Lu Mingxuan, the school’s most feared delinquent. But to her, he isn’t just some fictional character. He looks exactly like her brother. The same weary eyes. The same lonely back. The same silent cry for help no one else hears. Vowing to protect him this time, even if it means dragging her brother out of gang fights, squaring off against entitled rich kids, or defying the other villain himself—Gu Yunchen, the school’s cold and brilliant golden boy... and Lu Mingxuan's sworn rival. In the original novel, Gu Yunchen was one of the big villains—the cunning half-brother of the male lead. Now, he’s front and center... and watching her a little too closely.
