Record by Measure

What is regret? Maybe it's because I'm powerless after trying my best, or maybe I can't keep the people I want to keep, or I can't remember the things I want to remember. But if a butterfly cannot fly across the sea, who can bear to blame it? But fate never pities those who hesitate. Some people broke their oaths, some missed their return date; some were buried in the wind and snow, while some still walked with balance. The seven balances have fallen, and all living beings are playing chess. It was like this five hundred years ago, and it will be like this five hundred years from now. The introduction is too weak, please move to the main text ~
