Can the Sun Be Blue?

On the day I came home late from working overtime, at ten o'clock in the evening, I suddenly received a strange text message from my best friend Song Xu ——"Shu and I regret it. I don't want to marry Jiang Lingge." Jiang Lingge is Song Xu's fiancé, and we are both high school classmates. We got to know each other again seven years later while working. To my surprise, Song Xu had a crush on Jiang Lingge in high school. Now it can be regarded as getting what it wanted. So she won't regret it so easily. I called to find out why, but Song Xu's cell phone couldn't get through. When I rushed to her house anxiously, I received a call from the police. Song Xu committed suicide. I couldn't believe that someone as cheerful as her would commit suicide without warning, so I subconsciously thought of that strange text message. I suspect that Song Xu's death may be related to Jiang Lingge. Decided to ask him for details. But since that day, he disappeared. It was as if the world had evaporated without a trace. Until one day, at ten o'clock in the evening, I saw Jiang Lingge at the door of my house, and I walked towards him. At 10:01, time goes back, With Jiang Lingge within reach, I returned to seven years ago. The three of us in high school. This time, looking at Song Xu's unique eyes when he looked at Jiang Lingge, I lowered my eyes and took a deep, shaky breath. Since time goes back, then, cut off the unnecessary involvement, Will there be changes in the future? But later, whenever I thought I could change the future, The hand of fate has moved back to its original position again. [Two cycles, two rescues. ] ——"Shu Yu, can the sun be blue?" "Of course."
