Jie Yuhua and Huo Xiuxiu have known each other for fifty years. As I get older, there are still some things that cannot be said, cannot be said, or dare not be said. There is always a feeling above friendship, but there is never a chance to turn into love. Stay together for a lifetime without being involved in each other, miss each other for a lifetime without falling in love. When the paper was half burned in the evening, I realized that I had already fallen in love, but I never knew it, couldn't know it, and didn't dare to know it.
