Youth is an endless song.
That year, she loved him and he loved him too, ignorantly, young and sincere. However, what they had to face was reality. Years later, she asked him if we fell into the water, would he save me or her. He said, save her. She smiled.
That year, he regarded her as his best friend and watched her find her love, but found that he couldn't be happy for her. He wished her well. When he heard that they broke up and she left, he was very angry, but he didn't know that her departure was also because of him. Years passed and she came back. They were still friends, but they couldn't overcome the estrangement in their bones after so many years.
Youth, I just hope this song can be sung forever.
