This is a simple and beautiful story, at least in our eyes.
Maybe the words are childish, maybe the words are jerky, but this is our joint efforts, recording our lives, our efforts and gains.
Because this is our time machine, traveling through time but leaving indelible traces.
Maybe, we may become engineers, we may become bosses, we may also become good wives, mothers, fathers and husbands.
But these are things in the future, far, far away from us now, but time always passes by in a blink of an eye, leaving us melancholy and reminiscing.
Therefore, the story of retaining time appeared like this. I swear by our code name, you can't retain your youth, but you can retain us!
