The birthmark of the Big Dipper behind his ear is the cursor of destiny, and the physical formula on the back of the candy wrapper is the unspeakable star language. She hid her inferiority complex in her butterfly bones and used a stargazing diary to record every close moment - the shooting stars on Chunshu Street on a snowy night, the pencil-grey smile on his palm, and the melted mint candies in the infirmary.
