My name is Chen Mo. I'm a senior in high school, ranked dead last in the entire school. Three years ago, I ranked 3rd in my grade. Then I was hospitalized, and when I came out, I was completely ruined. Everyone thought I was a lost cause. Until the day I stood on the rooftop, a voice appeared in my head: "I am the 38-year-old you. The you from a parallel universe."He taught me how to memorize vocabulary, solve problems, and how to shut up everyone who looked down on me. In one month, I jumped from rank 1,187 to rank 198. The whole class accused me of cheating. I said, "Whatever."But no one knew there was a second person in my head. Her name is Lin Xiaoman. With a high ponytail, she sits on the classroom windowsill, swinging her legs and talking to me. No one else can see her. She is an illusion I created with my special power—so I wouldn't be alone, so I could survive until the day I was cured. I know she's fake. She knows it too. But I still fell in love with her.What I can't accept even more is this: once I'm cured, she will disappear. My mom doesn't exist on this timeline. I've already been dragged into a world no one told me about. Is this reincarnation, or a curse??
