Xu Zhou and I were in love for seven years. I thought we would end up together. But after taking a phone call at our engagement banquet, he left me behind. The voice on the other end belonged to a woman. He said she had loved him for years and was about to die in a car accident. She wanted to see him one last time. He said she was just a substitute, and that he had only ever loved me. He didn’t know that, in my eyes, he had become just a substitute too.
