Sometimes missed time can be made up for, but it is impossible for those who have missed it to say that they can start over again. And rebirth looks even more pathetic. Those who cannot let go will always live in pain. Those who let go may enjoy the moment, but who can guarantee that they will not regret it when they dream back at midnight and when their lives come to an end. In life, outsiders always say in an understatement: "Let it go," but insiders can only shake their heads and smile. Only those inside understand the past that cannot be let go. Even if you are reborn, some things cannot be let go. It won't change.
