Her Reversal Script

The sunlight at four o'clock in the afternoon slanted through the glass curtain wall of the Science Building of Linzhou University, casting diamond-shaped light spots on the marble floor of the corridor. There were fine dust floating in the air. The students filed out of the just-concluded "Introduction to Advanced Mathematics" open class. Talking and laughing, the sound of backpack zippers, and the sound of footsteps mixed into the most common afternoon noise on campus. Su Wan stood by the window in the corridor on the third floor, unconsciously rubbing the edge of the envelope with her fingers. The letter was very thick, and the light blue paper was specially chosen by her because it was said to make people feel calm. The back of the envelope was filled with tiny calculations written in very light pencil - this was her habit when she was nervous, as if those numbers and symbols could build a barrier to separate her pounding heartbeat. "Will he really accept it?" This thought came up for the hundredth time, and she pressed it down hard.
