In the Twilight That I Don't Know

My name is Cen Mu. I am among the top five in the city in the high school entrance examination and was admitted to the best high school in Zhejiang Province. I had a crush on a girl named Cheng Yuyan, who was also in the same class. I thought the most nervous thing about me on the first day of school was meeting her. But what I didn't know was - there was another girl sitting in the classroom. Her name is Shen Qinghan. She has very fair skin and freckles on the bridge of her nose. She looks ordinary. So ordinary that when I saw her bumping into someone at the school gate, I only glanced at her and looked away. What I didn't even know was that she knew me. Know me since three years ago. And I know nothing about her. The story of Class 1 and Class 3 begins here.
