For Lin'er, every summer vacation in the past always passed so quickly. She always felt as if someone had quietly set the clock during the summer vacation.
But the summer vacation after her senior year of high school was very, very long for her. It was so long that she couldn't tell how long the last summer vacation was in her heart. It was so long that it was fixed in that summer. Her summer vacation clock had stopped turning. After graduating from her senior year of high school, she had no chance to spend the summer vacation like a student.
But for some people, this summer vacation is short, so short that there are still many words left unsaid, so short that they want to go back to the last day of this summer vacation and take back those words that have been regretted for ten years.
