There really were geniuses who would only need to cast their eyes over their textbook once, at the start of school, and they wouldn't need to pay attention during class.

Looking nervous and a little shy, Qing'er fidgeted in her seat. She wondered what Gong Fan's note meant. Could it be that Gong Fan liked her too?
