The Setting Sun of Youth

Is it true that the person who loves you first will leave first? Youth is like a shooting star that breaks through the night, shining and fleeting. I thought I could catch the meteor. I thought I could control the trajectory and speed of the meteor. But no, I can't catch you or youth. It was well known that year that everyone knew that Tang Xu loved Xia Nuan, except Xia Nuan. Later, many things changed rapidly, catching everyone off guard. Tang Xu doesn't love Xia Nuan anymore, so no one knows, only Xia Nuan knows.
