This was a dream I had a long time ago. In the dream, I saw a young man in a brown suit walking out of the revolving door. His hair was soft and his complexion was white. The sunlight cast a layer of gold on his face and shoulders. He was so clean and beautiful, but I couldn't tell whether he was a boy or a girl. Now I write this story about him and give it to my dear Xiaowu classmate to commemorate the days when we "rotten" together.
